Recombinant Human Cluster Of Differentiation 4 （CD4）
Purified No Carrier Protein
（CD4mut, L3T4, Ly-4, CD4 Antigen）
Prod. No.: C1317
Source Sf 21 Insect Cells
Pkg. Size: 1 mg, 50 µg
Storage: -20°C to -70°C Detailed storage instructions below.

Description
Background:
CD4 （cluster of differentiation 4） is a glycoprotein expressed on the surface of T helper cells, regulatory T cells, monocytes, macrophages, ａnd dendritic cells. CD4 interacts with class II molecules of the major histocompatibility complex （MHC） enhancing the signal for T-cell activation.1

Molecular Weight
The predicted molecular weight of Recombinant Human Soluble CD4 is Mr 40 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 45 - 48 kDa.
State of Matter
Lyophilized
Formulation
This recombinant protein was 0.2 µm filtered ａnd lyophilized from modified Dulbecco’s phosphate buffered saline （1X PBS） pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.
Purity
>90% by SDS-PAGE ａnd analyzed by silver stain.
Storage ａnd Stability
This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
