ELISA Kits from Uscn


Uscn have a vast range of ELISA kits. This blog gives you a little more information about a few of their top sellers.

ELISA Kit for Connective Tissue Growth Factor (CTGF)

CTGF is a cysteine-rich, matrix-associated, heparin-binding protein. In vitro, CTGF mirrors some of the effects of TGF beta on skin fibroblasts, such as stimulation of extracellular matrix production, chemotaxis, proliferation and integrin expression. CTGF can promote endothelial cell growth, migration, adhesion and survival and is thus implicated in endothelial cell function and angiogenesis.

CTGF binds to perlecan, a proteoglycan which has been localised in synovium, cartilage and numerous other tissues. CTGF has been implicated in extracellular matrix remodelling in wound healing, scleroderma and other fibrotic processes, as it is capable of up regulating both matrix metalloproteinases and their inhibitors.

Product Code: E90010Hu

ELISA Kit for Platelet Activating Factor (PAF)

PAF is a potent phospholipid activator and mediator of many leukocyte functions, including platelet aggregation, inflammation, and anaphylaxis. It is produced in response to specific stimuli by a variety of cell types, including neutrophils, basophils, platelets, and endothelial cells. Several molecular species of platelet-activating factor have been identified which vary in the length of the O-alkyl side chain. It is an important mediator of bronchoconstriction. It causes platelets to aggregate and blood vessels to dilate. Thus it is important to the process of hemostasis. At a concentration of 10-12M, PAF causes life threatening inflammation of the airways to induce asthma like symptoms. Toxins such as fragments of destroyed bacteria induce the synthesis of PAF, which causes a drop in blood pressure and reduced volume of blood pumped by the heart, which leads to shock and maybe death.

Product Code: E90526Hu

ELISA Kit for Fibroblast Growth Factor 23 (FGF23)

FGF23 is located on chromosome 12 and is composed of three exons. Mutations in FGF23 that render the protein resistant to proteolytic cleavage leads to increased activity of FGF23 and the renal phosphate loss found in the human disease autosomal dominant hypophosphatemic rickets. FGF23 is also overproduced by some types of tumours, causing tumour-produced osteomalacia. Loss of FGF23 activity is thought to lead to increased phosphate levels and the clinical syndrome of familial tumour calcinosis. This gene was identified by its mutations associated with autosomal dominant hypophosphatemic rickets. Prior to discovery in 2000, it was hypothesized that a protein existed which performed the function of FGF23. This putative protein was known as phosphatonin.

Product Code: E90746Hu
