Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate TLN2 in samples. An antibody specific for TLN2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTLN2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TLN2 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TLN2 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:TLN2 encodes a protein related to talin 1, a cytoskeletal protein that plays a significant role in the assembly of actin filaments and in spreading and migration of various cell types, including fibroblasts and osteoclasts. This protein has a different pattern of expression compared to talin 1 but, like talin 1, is thought to associate with unique transmembrane receptors to form novel linkages between extracellular matrices and the actin cytoskeleton.
The deduced 2,532-amino acid protein contains a FERM domain. In TLN1, the FERM domain binds the cytodomains of beta-1 and beta-3 integrins, as well as to F-actin and other proteins. TLN2 shares 74% identity with TLN1, and the N- and C-terminal regions of TLN2 are highly conserved across species.
