Description
The Ha1/29 monoclonal antibody specifically binds to intergrin α2 chain (CD49b or VLA-2 α chain), the 160-kDa transmembrane glycoprotein that non-covalently associates with the intergrin β1 subunit (CD29) to form the intergrin α2β1 complex known as VLA-2. VLA-2, a receptor for collagen and laminin, is expressed on activated lymphocytes, epithelial cells, and platelets. It has been reported that Ha1/29 antibody can block VLA-2 binding to collagen and laminin. Ha1/29 antibody also reacts with mouse CD49b.
This antibody is routinely tested by flow cytometric analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.

FITC, fluorescein isothiocyanate, is a fluorochrome with a molecular weight of 389 Da. FITC is sensitive to pH changes and photobleaching. Due to nearly identical excitation and emission properties but different spillover characteristics, FITC and Alexa Fluor® 488 cannot be used simultaneously. FITC is relatively dim and should be reserved for highly expressed markers whenever possible.

Preparation and Storage
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
The antibody was conjugated with FITC under optimum conditions, and unreacted FITC was removed.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
