Drug Names
Generic Name: Human Lymphocyte activation gene-3 (LAG-3/CD223) ELISA Kit
Purpose
Our Human Lymphocyte activation gene-3 (LAG-3/CD223) ELISA kit is to assay LAG-3/CD223 levels in Human serum, plasma, culture media or any biological fluid.
Principle
This ELISA kit uses Sandwich-ELISA as the method. The Microelisa stripplate provided in this kit has been pre-coated with an antibody specific to LAG-3/CD223. Standards or samples are added to the appropriate Microelisa stripplate wells and combined to the specific antibody. Then a Horseradish Peroxidase (HRP)-conjugated antibody specific for LAG-3/CD223 is added to each Microelisa stripplate well and incubated. Free components are washed away. The TMB substrate solution is added to each well. Only those wells that contain LAG-3/CD223 and HRP conjugated LAG-3/CD223 antibody will appear blue in color and then turn yellow after the addition of the stop solution. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm. The OD value is proportional to the concentration of LAG-3/CD223. You can calculate the concentration of LAG-3/CD223 in the samples by comparing the OD of the samples to the standard curve.
