Overview of Human LOR(Loricrin) ELISA Kit

Product name:	Human LOR(Loricrin) ELISA Kit
Reactivity:	Human
Alternative Names:	LRN ; MGC111513
Assay Type:	Sandwich
Sensitivity:	0.055 ng/mL
Standard:	10 ng/mL
Range:	0.16-10 ng/mL
Sample Type:	Tissue homogenates, cell lysates and other biological fluids
Assay Length:	3.5h
Research Area:	Infection immunity;
Test principle:	The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Loricrin(LOR). Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Loricrin(LOR). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Loricrin(LOR), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in colour. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the colour change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Loricrin(LOR) in the samples is then determined by comparing the OD of the samples to the standard curve.

[accordion title= “Precision“]

Intra-assay Precision (Precision within an assay)： CV%<8% Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision. Inter-assay Precision (Precision between assays)： CV%<10% Three samples of known concentration were tested in forty separate assays to assess inter-assay precision. [/accordion] [accordion title= "Recovery“]

Matrices listed below were spiked with a certain level of recombinant LOR and the recovery rates were calculated by comparing the measured value to the expected amount of LOR in samples.

Matrix	Recovery range	Average
serum(n=5)	80-93%	86%
EDTA plasma(n=5)	94-105%	98%
Heparin plasma(n=5)	95-107%	101%

[accordion title=”Linearity“]

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of LOR and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
