Human FGL1 (Fibrinogen Like Protein 1) Microsample ELISA Kit

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 Human FGL1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human FGL1. 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 Human FGL1, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human FGL1 in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 1.56-100 ng/mL. Sensitivity: 0.53 ng/mL. Assay Type: Sandwich. Standard: 100 ng/mL. Sample Type: splasma. Assay duration: 3.5h. Protein Function: Immune suppressive molecule that inhibits antigen-specific T-cell activation by acting as a major ligand of LAG3 (PubMed:30580966). Responsible for LAG3 T-cell inhibitory function (PubMed:30580966). Binds LAG3 independently from MHC class II (MHC-II) (PubMed:30580966). Secreted by, and promotes growth of, hepatocytes (PubMed:11470158, PubMed:19880967) [The Uniprot Consortium]
