SNP Testing Services Overview

Single nucleotide polymorphism (SNP) testing is used for annual monitoring of the genetic background of rats and mice, detection of gene mutations or genetic contaminations and batch testing of rat and mouse mutants.

Why GemPharmatech

One-stop solution: We provide a one-stop solution for SNP testing from primer design to result reporting.

Rich experience: Since establishing the high-throughput testing platform, we have cumulatively tested more than 100,000 data points.

Stable genetic testing panel: We have successfully developed SNP panels applicable to genetic testing and speed congenics for 13 inbred mouse strains.

SNP Testing Services

SNP testing refers to the conversion, transversion, insertion, and deletion of a single base arising from the mutation of a single nucleotide with a mutation frequency greater than 1% in a population. As a third-generation genetic molecular marker, the SNP labeling technique possesses numerous advantages in genetic quality monitoring as compared with other genetic markers, including wide distribution, good genetic stability, impressive representativeness, and easier implementation of high-throughput and automatic monitoring. As a result, it has been widely applied in agriculture, pharmaceutical, life science, and other research fields.

We can perform SNP testing using KASP (Kompetitive Allele Specific PCR) for the following purposes:

1. Annual monitoring of genetic background of rats and mice: Annual genetic testing for laboratory animals is an essential approach to evaluate and ensure the quality of laboratory animals, especially for which regular genetic background monitoring is necessary.
2. Testing for genetic mutation and contamination in rats and mice: This test should be performed when a new phenotype is identified or when a mismatched rat/mouse is suspected during a study.
3. Batch testing of rat and mouse mutants: SNP testing can be used for precise genotyping of InDels (insertions and deletions).

   X: HEX Channel Y: FAM Channel
   Red dots：FAM/FAM, Blue dots: HEX/HEX, Black dots: blank control.

4. High-throughput KASP based on available SNP loci information is utilized for precise allele genotyping of specified SNPs and InDels in diverse genome samples (including complicated genomic DNA samples), employing fluorescence detection with high sensitivity. In terms of technological principle, it is identical to Taqman assay (the gold standard) and produces consistent accuracy. Unlike traditional Taqman assays, however, amplification of the general fluorescence primer is available for assay at all loci based on the unique ARM PCR approach, rather than requiring a probe or primer generated for each target. We have optimized PCR methods to address the needs of high-throughput reactions at various loci. While the accuracy of KASP is comparable to the gold standard Taqman test, it is more economical and has better loci adaptability.

Genetic Integrity

[/vc_column_text][vc_column_text]

Breeding System

In recent years, as the biomedical industry has flourished, the resources of laboratory rodent strains have expanded, and the demand for quality laboratory rodents has increased. A critical concern for laboratory animal providers is to avoid genetic drifting and genetic contamination in order to deliver high-quality and reliable laboratory animals to researchers.

GemPharmatech has developed a strict breeding management system that ensures the genetic quality of various mouse strains is consistent with international standards and maintains genetic stability in long-term breeding and commercial production. This system was developed based on our many years of experience in breeding laboratory animals.

The central premise of breeding all inbred and pure strains of mice is that the animals’ homozygosity and genetic purity must be maintained, and all strains must have detailed records of strain breeding and pedigree charts. Our breeding management system strictly controls and reduces genetic contamination and drift during the breeding process, providing researchers with high-quality animals that have consistent and genetically stable features.

Our mouse population structure is a compact pyramid, with production lines consisting of a foundation group, a pedigree expansion group, and a production group.[/vc_column_text][vc_column_text]

	Foundation group: sibling pairs, up to three generations are maintained simultaneously; cryopreservation of genetic material and resuscitation after 10 generations of continuous breeding; annual SNP monitoring.       Pedigree expansion group: all sibling pairings are within 2 generations, up to 5 generations of common ancestors, annual SNP monitoring with statistical assessment.
	Product group:  all sibling pairings are within 2 generations, up to 5-10 generations of common ancestors, annual SNP monitoring with statistical assessment.

We ensure continuous and uninterrupted breeding of a large number of mouse strains for at least 50 years by employing this system. The population has only passed down two generations, reducing the risk of genetic variation and drift during breeding.

Genetic Monitoring Systems

GemPharmatech uses single nucleotide polymorphisms (SNPs) to track the genetics of live breeding colonies at each of our facilities.

GemPharmatech chose 19 autosomes and 1 X chromosome for various inbred strains, selected monitoring loci on each chromosome at approximately equal distances, and targeted some strain-specific genetic loci by consulting academic papers to construct a library of nearly one thousand specific SNP monitoring loci. On this premise, we have built a panel of 96 SNPs for each inbred or isogenic inbred line, which is adequate to distinguish all the in-house inbred strains and to ensure the genetic stability of each line.

GemPharmatech conducts annual genetic monitoring of the foundation groups of select lines and the production groups of select lines. In addition, we sample inbred background lines each year to ensure the stable genetic background for all newly engineered mouse strains.[/vc_column_text][/vc_tta_section][vc_tta_section title=”Animal Health” tab_id=”1677454144610-d26ce63f-f3af”][vc_column_text css=”.vc_custom_1677458290715{padding-top: 60px !important;padding-bottom: 60px !important;background-image: url(https://atlantis2.elsbiz.website/wp-content/uploads/2023/02/title-banner.jpg?id=81004) !important;}”]

• All staff must enter with access cards, adhere strictly to the personnel entry and exit procedure, wear disposable protective clothing (shoes, gloves, hair caps, masks, and a complete set of PPE (disposable protective clothing, shoes, gloves, hair caps and masks), and shower before entering the production area.
• To reduce the risk of cross-contamination, all staff members must restrict the use of facilities and rooms.

Breeding Management

Breeding Facilities

The GemPharmatech facility is a barrier environment, and SPF mice are housed in centrally ventilated IVC cages and proprietary IVU cages.

Feed

Co60 irradiated and sterilized vacuum-packed pellet feed is obtained from qualified suppliers, and third-party test reports are provided annually, including testing for nutrient content, heavy metals, pesticide residues, and microbes.

The storage warehouse is controlled for temperature, humidity, and pests. The feed is positioned off the wall and the floor and each batch of feed is sampled and tested for sterility before being used in the facility. Mice are fed ad libitum. Feeding containers are replaced every one to two weeks.

Bedding and nesting materials

Corn cob bedding and shavings bedding are procured from qualified suppliers, and third-party test reports are included. Testing on hygiene, chemical contamination, and microbes are conducted annually. Each batch of bedding material is inspected for particle size, color, odor, and contaminants and is stored away from walls and floors. The bedding material is autoclaved before entering the facility.

Drinking water

In order to provide mice with clean water, GemPharmatech utilizes the Edstrom Automatic Drinking Water System with RO reverse osmosis and chlorine treatment. The drinking water is routinely tested for sterility.

Disinfection

The GemPharmatech facility is equipped with several sets of advanced production support equipment. We have high-capacity sterilizing equipment, a multi-floor hydrogen peroxide fumigation and disinfection system, and an automated production line for centralized bedding processing, cleaning, and refilling. Before entering the facility, all materials are sterilized, and all rooms and items are disinfected.

Animal health monitoring

GemPharmatech employs a monitoring system to assure the microbiological quality , decontaminated offspring, environmental (dust) monitoring of breeding mice. The test samples include sentinel mice and breeding stock mice. The test consists of 48 items. In addition, animals are sampled quarterly and sent to third-party testing institutions for monitoring.

Each side of the rack contains a sentinel mouse cage to determine the microbiological status of the animals. The sentinel mouse cage is positioned closest to the air outlet. Healthy female mice(4-6 weeks old) are used for at least eight weeks in a cage with 100% dirty bedding. Monitoring sentinel mice quarterly includes bacterial, viral, parasitic, and necropsy testing.

In addition to standard microbiological surveillance, our staff observes the health of the animals daily, and any aberrant mice are referred to the examining veterinarian for clinical diagnosis, ensuring the mouse’s health and welfare.[/vc_column_text][vc_column_text][/vc_column_text][/vc_tta_section][vc_tta_section title=”Animal Welfare” tab_id=”1677455385119-2a926812-e758″][vc_column_text css=”.vc_custom_1677458597616{padding-top: 60px !important;padding-bottom: 60px !important;background-image: url(https://atlantis2.elsbiz.website/wp-content/uploads/2023/02/title-banner.jpg?id=81004) !important;}”]
