Purified Mouse Anti-Pig CD8b

CD8 expression on peripheral blood lymphocytes. Yorkshire pig whole blood was stained with purified 295/33-25 monoclonal antibody followed by FITC-conjugated anti-mouse IgG2a mAb R19-15 (Cat. No. 553390), then PE-conjugated mAb 74-12-4 (anti-pig CD4a, Cat. No. 559586). Erythrocytes were lysed (BD PharmLyse™, Cat. No. 555899), non-viable leukocytes were excluded by staining with 7-AAD (BD Via-Probe™, Cat. No. 555816/555815), and lymphocytes were gated according to scatter profile. Flow cytometry was performed on a BD FACSCalibur™ Flow Cytometry System.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  3. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.
  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.

295/33-25

The 295/33-25 monoclonal antibody specifically binds to an epitope on the CD8α chain, a 35 kDa antigen expressed on thymocytes, peripheral T lymphocytes, and NK cells. The CD8 molecule can exist as a 70 kDa homodimer, composed of α chains, or heterodimer, composed of an α and a β chain. Two peripheral CD8+ T-cell populations can be distinguished in the pig: CD8-bright CD4-negative CTL effectors/precursors and CD8-dull CD4-positive T-helper lymphocytes. Pig NK cells express CD8 (dull staining), CD2, MHC class II, LFA-1, and asialo-GM1; but not CD3, CD4, CD5, or CD6. mAb 295/33-25 was clustered as anti-CD8b at the First International Swine CD workshop.

Purified
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
