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

CD4 produced in Sf9 Insect cells is a single, glycosylated polypeptide chain containing 377 amino acids (26-396a.a.) and having a molecular mass of 42.1kDa (Molecular size on SDS-PAGE will appear at approximately 40-57kDa).CD4 is expressed with a 6 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.

Source

Physical Appearance

Sterilefiltered colorless solution.

Formulation

CD4 a protein solution (0.25mg/ml) contains phosphate buffered saline (pH7.4) and 10% glycerol.

Stability

Store at 4°C if entire vial will be used within 2-4 weeks.Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.
