Description
The HMα5-1 antibody specifically recognizes the α5 subunit of the integrin α5β1 fibronectin receptor (CD49e/CD29, VLA-5) on mouse thymocytes and a variety of mouse cell lines, including pre-B and non-lymphoid cells, but not on mouse splenic or lymph node cells. It also detects rat CD49e on the RBL2H3 basophilic leukemia cell line,peritoneal mast cells, and endothelium, but not on splenocytes. It has been reported that soluble mAb HMα5-1 partially inhibits in vitro binding of a mouse cell line and of rat mast cells to fibronectin and inhibits the enhanced degranulation of IgE-sensitized rat RBL cells induced on fibronectin-coated plates. It has also been observed that plate-bound HMα5-1 antibody enhances the degranulation of IgEsensitized rat RBL-2H3 cells and that subcutaneous injection of HMα5-1 mAb into rats, along with anti-CD49d and anti-CD61 antibodies, inhibits experimentally induced passive cutaneous anaphylaxis.
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
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 the dye under optimum conditions that minimize unconjugated dye and antibody.

4. 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.
5. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
6. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
7. Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.

9. An isotype control should be used at the same concentration as the antibody of interest.
