CD8A Antibody

• Catalog Number: orb386200
• Category: Antibodies
• Description: CD8 is a cell surface receptor expressed either as a heterodimer with the CD8 beta chain (CD8 alpha/beta) or as a homodimer (CD8 alpha/alpha). A majority of thymocytes and a subpopulation of mature T cells and NK cells express CD8a. CD8 binds to MHC class 1 and through its association with protein tyrosine kinase p56lck plays a role in T cell development and activation of mature T cells. For mature T-cells, CD4 and CD8 are mutually exclusive, so anti-CD8, generally used in conjunction with anti-CD4. It is a useful marker for distinguishing helper/inducer T-lymphocytes, and most peripheral T-cell lymphomas are CD4+/CD8-. Anaplastic large cell lymphoma is usually CD4+ and CD8-, and in T-lymphoblastic lymphoma/leukemia, CD4 and CD8 are often co-expressed. CD8 is also found in littoral cell angioma of the spleen.
• Clonality: Recombinant

• Conjugation: Unconjugated
• Reactivity: Human
• Immunogen: Recombinant full-length human CD8a protein was used as immunogen for this recombinant CD8 antibody.
• UniProt ID: P01732
• Tested applications: IHC-P
• Dilution range: Immunohistochemistry (FFPE): 0.5-1ug/ml for 30 min at RT
• Application notes: The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the recombinant CD8 antibody to be titered up or down for optimal performance.1. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.

IHC testing of FFPE human lymphoma with recombinant CD8 antibody (clone C8/1779R). Required HIER: boil tissue sections in 10mM citrate buffer, pH6, for 10-20 min followed by cooling at RT for 20 min.

SDS-PAGE analysis of purified, BSA-free recombinant CD8 antibody (clone C8/1779R) as confirmation of integrity and purity.
