PE Hamster Anti-Mouse CD49b

BD Pharmingen™ PE Hamster Anti-Mouse CD49b

Name: PE Hamster Anti-Mouse CD49b
Brand: BD Pharmingen™
SKU: 558759

Clone HMα2

(RUO)

Two-color analysis of CD49b expression on spleen leukocytes. BALB/c splenocytes were simultaneously stained with PE-conjugated mAb HMα2 mAb (right panel) and FITC-conjugated mAb M1/70 (anti-mouse CD11b, Cat. No. 557396/553310, both panels). Flow cytometry was performed on a BD FACScan™ Flow Cytometry System.

Product Notices

Since applications vary, each investigator should titrate the reagent to obtain optimal results.

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.
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.

Antibody Details

HMα2

The HMα2 antibody reacts with integrin α2 chain (CD49b), the 150-kDa transmembrane glycoprotein that non-covalently associates with the integrin β1 subunit (CD29) to form the integrin α2β1 complex known as VLA-2. VLA-2, a receptor for collagen and laminin, is expressed on some splenic CD4+ T lymphocytes and NK-T cells, intestinal intraepithelial and lamina propria lymphocytes, splenic NK cells, epithelial cells, and platelets; but it is not on thymocytes or Peyer's-patch or lymphnode lymphocytes. The expression of VLA-2 is upregulated on lymphocytes in response to mitogens. The HMα2 antibody has been reported to partially block the interaction of T-cell blasts, but not NK cells, with collagen. Purified HMα2 mAb blocks the staining of splenic NK cells by the anti-CD49b/Pan-NK Cells mAb DX5 (Cat. No. 553858, for the PE conjugate). Therefore, mAb HMα2 may be used like the DX5 mAb for identification of NK cells.

Format Details

R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
