Formulation

This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added.

Product Preparation

Functional grade preclinical antibodies are manufactured in an animal free facility using only In vitro protein free cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.

Storage and Handling

Functional grade preclinical antibodies may be stored sterile as received at 2-8°C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -80°C. Avoid Repeated Freeze Thaw Cycles.

Description

Specificity

Clone 53-5.8 recognizes an epitope on mouse CD8b.2.

Antigen Distribution

CD8b.2 is expressed on the majority of thymocytes and cytotoxic T cell subsets.

Background

CD8 is made up of disulfide-linked α and β chains that form the α(CD8a)/β(CD8b) heterodimer and α/α homodimer. CD8 is part of the Ig superfamily that expresses primarily as CD8a homodimers. CD8a is a 32-34 kD type I glycoprotein that can also form heterodimers with CD8b. CD8 is an antigen co-receptor on T cells that mediates efficient cell to cell interactions within the immune system. CD8 coupled with the T cell receptor on the T lymphocyte recognizes an antigen displayed by an antigen presenting cell (APC) in the context of class I MHC molecules. The CD8 co-receptor also plays a role in T cell signaling by interacting with Lck (lymphocyte-specific protein tyrosine kinase) which leads to the activation of transcription factors that affect the expression of certain genes.
