Description
The Ha31/8 monoclonal antibody specifically binds to the 180-kDa integrin α1 chain (CD49a), which is a transmembrane glycoprotein that non-covalently associates with the integrin β1 subunit (CD29) to form the α1β1 (complex known as VLA-1). VLA-1 has been reported to be expressed on activated T cells, monocytes, smooth muscle cells, and endothelial cells. It is a receptor for collagen and laminin. The Ha31/8 monoclonal antibody is specific for both rat and mouse CD49a. It has been reported that Ha31/8 antibody can block VLA-1-mediated binding of rat cells to collagen.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.

4. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
5. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

7. Although hamster immunoglobulin isotypes have not been well defined, BD Biosciences Pharmingen has grouped Armenian and Syrian hamster IgG monoclonal antibodies according to their reactivity with a panel of mouse anti-hamster IgG mAbs. A table of the hamster IgG groups, Reactivity of Mouse Anti-Hamster Ig mAbs, may be viewed at http://www.bdbiosciences.com/documents/hamster_chart_11x17.pdf.
8. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
9. An isotype control should be used at the same concentration as the antibody of interest.
