This CD44 protein is has a purity of more than 90% and endotoxin content of less than 1.0 EU/ug. It is a biologically active protein. Its activity has been determined through a functional ELISA in which the anti-CD44 antibody can bind to this CD44 protein with the EC₅₀ of 2.865-5.099 ng/ml. This CD44 protein is a biotinylated protein and is suitable for ELISA, Western blot, surface plasma resonance, and other relevant assays. It is available now and can reach your experimental bench faster.

CD44 participates in various physiological processes, including cell proliferation, adhesion, migration, hematopoiesis, and lymphocyte activation, homing, and extravasation. It is implicated in numerous diseases such as cancer, arthritis, interstitial lung disease (ILD), vascular disease, wound healing, and infections by pathogens.

Target Background

Function

Cell-surface receptor that plays a role in cell-cell interactions, cell adhesion and migration, helping them to sense and respond to changes in the tissue microenvironment. Participates thereby in a wide variety of cellular functions including the activation, recirculation and homing of T-lymphocytes, hematopoiesis, inflammation and response to bacterial infection. Engages, through its ectodomain, extracellular matrix components such as hyaluronan/HA, collagen, growth factors, cytokines or proteases and serves as a platform for signal transduction by assembling, via its cytoplasmic domain, protein complexes containing receptor kinases and membrane proteases. Such effectors include PKN2, the RhoGTPases RAC1 and RHOA, Rho-kinases and phospholipase C that coordinate signaling pathways promoting calcium mobilization and actin-mediated cytoskeleton reorganization essential for cell migration and adhesion.
