Description
Principle of the Assay: Mouse ALK-1/ACVRL1 ELISA Kit was based on standard sandwich enzyme-linked immunesorbent assay technology. A monoclonal antibody from mouse specific for ALK-1/ACVRL1 has been precoated onto 96-well plates. Standards(Expression system for standard: NSO; Immunogen sequence: D23-P119) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for ALK-1/ACVRL1 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Mouse ALK-1/ACVRL1 amount of sample captured in plate.
Background/Introduction: Serine/threonine-protein kinase receptor R3 is an enzyme that in humans is encoded by the ACVRL1 gene. It is also known as activin receptor-like kinase 1, or ALK1. This gene encodes a type I cellsurface receptor for the TGF-beta superfamily of ligands. It shares with other type I receptors a high degree of similarity in serine-threonine kinase subdomains, a glycine- and serine-rich region (called the GS domain) preceding the kinase domain, and a short C-terminal tail. The encoded protein shares similar domain structures with other closely related ALK or activin receptor-like kinase proteins that form a subfamily of receptor serine/threonine kinases. Mutations in this gene are associated with hemorrhagic telangiectasia type 2, also known as Rendu-Osler-Weber syndrome 2
