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.

Pathogen Testing

To protect mouse colonies from infection by pathogens and to assure that experimental preclinical data is not affected by such pathogens, all of Leinco’s Purified Functional PLATINUM™ antibodies are tested and guaranteed to be negative for all pathogens in the IDEXX IMPACT I Mouse Profile.

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 OKT4 recognizes Human CD4. This clone recognizes a different epitope than the RPA-T4 monoclonal antibody, and these antibodies do not interfere with each other.

Antigen Distribution

CD4 is expressed on most thymocytes, a subset of T cells, and monocytes/macrophages, and may be detected in thymus, lymph nodes, tonsils, and spleen, and also in specific regions of the brain, gut, and other non-lymphoid tissues.

Background

CD4 is a 55 kD single-chain type I transmembrane glycoprotein and a member of the Ig superfamily. It is involved in the recognition of MHC class II molecules. Furthermore, CD4 is the primary receptor for HIV. CD4 initiates the early phase of T-cell activation via its association with the T-cell receptor complex and protein tyrosine kinase, Lck. In addition, CD4 functions as a mediator of direct neuronal damage in infectious and immune-mediated diseases of the central nervous system.
