Bulk Anti-Human CD8 (UCHT-4) Antibody

Product Specifications

Background

Anti-CD8 may be used in studies of immunoregulation and T-lymphocyte mediated suppression, autoimmune disorders, immunodeficiency states and acute lymphoblastic leukemia and lymphoma.

Specifications

Anti-CD8 In Vivo Antibody - Low Endotoxin (UCHT-4) recognizes Human CD8. Anti-Human CD8 recognizes a T-cell glycoprotein cell surface complex (Mr 32 kDa) which defines the cytotoxic/suppressor population of mature T-lymphocytes. The CD8 complex interacts with class I MHC molecules resulting in increased adhesion between CD8+ T-lymphocytes and their target cells. Binding of the CD8 antigen to Class I MHC molecules enhances T-cell activation. The cytoplasmic portion of the CD8 antigen is associated with a protein tyrosine kinase (p56lck).

Formulation

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

Antigen Distribution

The CD8 antigen is expressed on approximately 19-48% of normal human peripheral blood lymphocytes and > 90% of normal thymocytes. It is also present on a subset of NK cells. Subjects infected with HIV have been shown to exhibit increased levels of CD8+ lymphocytes with a continual decrease in CD4+ lymphocytes.

Aggregation

Aggregation level ≤ 5%

Applications Notes

Each investigator should determine their own optimal working dilution for specific applications.
