Stability and Storage

12 months from date of receipt at -20°C to -70°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for almost 6 months (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

BACKGROUND

CD4 is a monomeric glycoprotein expressed on approximately 60% of peripheral blood T lymphocytes. CD4 (T4), a glycoprotein expressed largely on the surface of cells in the immune system, serves as the receptor for the human immunodeficiency virus, HIV. HIV infection leads to a progressive reduction of the number of T cells possessing CD4 receptors. CD4 is a co-receptor that assists the T cell receptor (TCR) to activate its T cell following an interaction with an antigen-presenting cell. The CD4 molecule plays an important role in the development of CD4+T lymphocytes and it also acts as a coreceptor to enhance responses mediated via the TCR and also subserves as the receptor for the human immunodeficiency viruses.

Data

SDS-PAGE

Bioactivity

Active Recombinant Mouse CD4 Protein was determined by SDS-PAGE with Coomassie Blue, showing band at 42-55 kDa.

Immobilized Mouse CD4, His Tag at 3 μg/mL (100 μL/well) can bind Anti-CD4 with a linear range of 0.06-0.94 ng/mL.
