Human CD4/LEU3 Protein (CD4-HM204) Summary

Product Description	Recombinant Human CD4/LEU3 Protein is expressed from HEK293 with hFc at the C-Terminus.It contains Lys26-Trp390.
Product Background	CD4, also known as L3T4, T4, and W3/25, is an approximately 55 kDa type I transmembrane glycoprotein that is expressed predominantly on thymocytes and a subset of mature T lymphocytes. It is a standard phenotype marker for the identification of T cell populations.Integral membrane glycoprotein that plays an essential role in the immune response and serves multiple functions in responses against both external and internal offenses. In T-cells, functions primarily as a coreceptor for MHC class II molecule:peptide complex.
Product Category	Recombinant Protein / Antibody discovery / CAR-T targets

Human CD4/LEU3 Protein (CD4-HM204) Specifications/Details

Protein	CD4/LEU3
Synonyms	CD4 antigen (p55); CD4 molecule; CD4 receptor; CD4; CD4mut; EU3
Accession	P01730
Species	Human
Biotinylated	no
Amino Acid Range	Lys26-Trp390
Molecular Weight	The protein has a predicted MW of 67.5 kDa. Due to glycosylation, the protein migrates to 70-80 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human CD4 at 1ug/ml (100ul/Well) on the plate. Dose response curve for Biotinylated Anti-CD4 Antibody, hFc Tag with the EC50 of 15.4ng/ml determined by ELISA (QC Test). See testing image for detail.
Product Tag	C-hFc
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1 EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS, 100mM L-arginine (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
