Relevance
Thrombospondin is a regulator of many biological processes including cell growth, adhesion, migration, platelet aggregation, and fibrin deposition and lysis. It interacts with a number of plasma proteins such as fibrinogen and plasminogen and co-polymerizes with fibrin in clot formation. Thrombospondin also has multiple binding sites that interact with molecules such as fibronectin, collagens, laminin and heparan sulphate proteoglycans as well as binding growth factors such as TGF-beta1. Thrombospondin exerts an anti-adhesive effect which leads to cell rounding and detachment. -

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol and sodium azide ab267388.
Thrombospondin 1 was immunoprecipitated from 0.35 mg mouse platelets whole cell lysate 10µg with ab267388 at 1/30 dilution (2µg in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab267388 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366) was used at 1/5000 dilution.
Lane 1: Mouse platelets whole cell lysate 10µg.
Lane 2: ab267388 IP in mouse platelets whole cell lysate.
Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab267388 in mouse platelets whole cell lysate.
Blocking and dilution buffer and concentration: 5% NFDM/TBST.
Exposure time: 8 seconds.
