Product Overview
Recombinant Feline sCD4 protein (Met1-Leu413, Lys20Glu, Ser84Cys, Val103Ile, Asn115Asp, Ser142Thr, Ser169Gly & insertions of SerThr between Thr148 and Ser149) with a C-terminal 6×His tag was expressed in Mouse myeloma cell line.
Description
This gene encodes the CD4 membrane glycoprotein of T lymphocytes. The CD4 antigen acts as a coreceptor with the T-cell receptor on the T lymphocyte to recognize antigens displayed by an antigen presenting cell in the context of class II MHC molecules. The CD4 antigen is also a primary receptor for entry of the human immunodeficiency virus through interactions with the HIV Env gp120 subunit. This gene is expressed not only in T lymphocytes, but also in B cells, macrophages, granulocytes, as well as in various regions of the brain. The protein functions to initiate or augment the early phase of T-cell activation, and may function as an important mediator of indirect neuronal damage in infectious and immune-mediated diseases of the central nervous system. Multiple alternatively spliced transcript variants encoding different isoforms have been identified in this gene.

Form
Lyophilized from a 0.2 μm filtered solution in PBS.
Met1-Leu413, Lys20Glu, Ser84Cys, Val103Ile, Asn115Asp, Ser142Thr, Ser169Gly & insertions of SerThr between Thr148 and Ser149
Bio-activity
Measured by the ability of the immobilized protein to support the adhesion of NIH-3T3 mouse embryonic fibroblast cells. The ED50 for this effect is 0.1-0.5 μg/mL after a 1 hour incubation at 37 centigrade. Optimal dilutions should be determined by each laboratory for each application.
Endotoxin
<0.01 EU/μg of the protein by the LAL method.
Purity
>95%, by SDS-PAGE under reducing conditions and visualized by silver stain.
Storage
Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70 centigrade as supplied. 1 month, 2 to 8 centigrade under sterile conditions after reconstitution. 3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
