Clone Host Grade Applications
Monoclonal Mouse Affinity Purified B
Thrombospondin is a protein from platelet a-granules. It is made up of three identical subunits bound by interchain disulfides. It is secreted at sites of platelet activation and aggregation and is involved in the processes of chemotaxis, adhesion, proliferation and differentiation of leukocytes, fibroblasts, smooth muscle and endothelial cells.
Catalog #T5100-21X
ApplicationsSuitable for use in Electron Microscopy and Western Blot. Not suitable for Immunohistochemistry. Other applications not tested.
Recommended DilutionsWestern Blot: 1-2ug/ml for 2 hours at RT. Detects ~450kD band (non-reducing) or 170-180kD band (reducing)
Optimal dilution to be determined by the researcher.
Cellular LocalizationSecretory granules, Golgi complex, endoplasmic reticulum, extracellular matrix

PurityPurified by Protein G affinity chromatography.
ImmunogenReduced and alkylated puri ed human TSP (fully denatured) from the supernatant of thrombin-activated platelets. Epitope: Calcium-binding domain of TSP (C-terminal 50kD piece of the 120kD fragment).
SpecificityRecognizes human Thrombospondin 1. Reacts with 140kD and 120kD fragments in digest of Ca2+-replete TSP which are absent from digest in EDTA. Its binding to TSP is enhanced by EDTA i.e. at low [Ca2+]. Does not crossreact with fibronectin, fibrinogen, TSP-2 and von Willebrand factor. Species Crossreactivity: mouse, rat, bovine, porcine, equine, canine and sheep.
