Introduction

CD4 is a cell-surface glycoprotein found on the mature helper T cells and immature thymocytes, as well as on monocytes and macrophages. (Some cytotoxic T cells have CD4 protein as well.) Normally, about 65% of T cells in the blood are CD4+ (have CD4 protein protruding from their membrane). A mature T cell with either have CD4 or CD8, but not both. During one stage of development T cells develop CD4 and CD8 receptors, but they eventually are differentiated in the thymus and become more specialized.

Description

sCD4 Human Recombinant produced in Baculovirus is a single, glycosylated polypeptide chain containing 365 amino acids and having a non glycosilated molecular mass of 45 kDa. As a result of glycosilation the sCD4 migrates as a 46 kDa protein on standard SDS-PAGE. Detected By Western Imunno Blots anti CD4 monoclonal antibody.
The sCD4 is purified by proprietary chromatographic techniques.

Source

Baculovirus.

Physical Appearance

Sterile Filtered colorless solution.

Formulation

The solution contains 10mM sodium phosphate buffer pH-7.0, 300mM NaCl and 0.01% tween-80.

Stability

sCD4 Human Recombinant although stable at 4°C for 1 week, should be stored desiccated below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Purity

Greater than 90.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
