T-cell surface glycoprotein CD4 is also known as T-cell surface antigen T4/Leu-3. CD4 contains three Ig-like C2-type (immunoglobulin-like) domains and one Ig-like V-type (immunoglobulin-like) domain. CD4 is accessory protein for MHC class-II antigen/T-cell receptor interaction. CD4 induces the aggregation of lipid rafts. CD4 is a primary receptor used by HIV-1 to gain entry into host T cells. HIV infection leads to a progressive reduction of the number of T cells possessing CD4 receptors. Therefore, medical professionals refer to the CD4 count to decide when to begin treatment for HIV-infected patients.

Recombinant Human CD4, Fc Tag (MALS verified) (CD4-H5259) is expressed from human 293 cells (HEK293). It contains AA Lys 26 - Pro 396 (Accession # AAH25782).
Predicted N-terminus: Lys 26

Molecular Characterization
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 67.5 kDa. The protein migrates as 70-80 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Less than 1.0 EU per μg by the LAL method.

>95% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.

Lyophilized from 0.22 μm filtered solution in Tris, Glycine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

See Certificate of Analysis for details of reconstitution instruction and specific concentration.
