Anti-Mouse CD8a (53-6.7) In Vivo Antibody - Low Endotoxin

Product Specifications

Background

CD8, a.k.a Lyt-2, Ly-2, or T8, consists of disulfide-linked A and β chains that form the A(CD8a)/β(CD8b) heterodimer and A/A homodimer. CD8a is a 34 kD protein that belongs to the immunoglobulin family. The CD8 A/β heterodimer is expressed on the surface of most thymocytes and a subset of mature TCR A/β T cells.

CAS Number

9007-83-4

Storage Conditions

Anti-CD8a In Vivo Antibody - Low Endotoxin (53-6.7) is stable for at least one week when stored sterile at 2-8°C. For long term storage aseptically aliquot in working volumes without diluting and store at –80°C. Avoid Repeated Freeze Thaw Cycles.

Formulation

0.01 M phosphate buffered saline (PBS) pH 7.2, 150 mM NaCl with no carrier protein, potassium or preservatives added.

Antigen Distribution

Present on the surface of most thymocytes and a subpopulation of mature T-lymphocytes which include most T suppressor/cytotoxic cells. CD8 participates in T-cell activation through its association with the T-cell receptor complex and protein tyrosine kinase lck.

Aggregation

Aggregation level ≤ 5%

Applications Notes

Immunoprecipitation: Rat Anti-Mouse CD8a (Clone 53-6.7) precipitates 44 kDa and 33 kDa proteins. Each investigator should determine their own optimal working dilution for specific applications.
