Product Information
KE00258 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The human FLRG ELISA kit is to be used to detect and quantify protein levels of endogenous human FLRG. The assay recognizes human FLRG. An antibody specific for human FLRG has been pre-coated onto the microwells. The human FLRG protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody of biotinylated specific for human FLRG is added to detect the captured human FLRG protein. For signal development, Streptavidin-HRP is added, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.

Background Information
Follistatin-like 3 (FSTL3), also called follistatin-related protein or follistatin-related gene (FLRG) protein, is a highly conserved monomer secreted glycoprotein located on chromosome 19p13.3. The FSTL3 gene is the target of a novel chromosomal rearrangement discovered by Hayette et al in 1998 in B cells of patients with chronic lymphocytic leukemia. FSTL3 can modulate target gene expression via members of the transforming growth factor β (TGF-β) superfamily. Recent literatures have revealed that FSTL3 regulates multiple biological processes, including cell differentiation, aging, obesity development, arteriosclerosis development, and tumor progression.
