Name : Human CD38 Protein
Product Source :
Recombinant Human CD38 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Val43-Ile300.[Accession | P28907-1]
Molecular Weight :
The protein has a predicted MW of 30.7 kDa. Due to glycosylation, the protein migrates to 45-58 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3-6 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Human CD38 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human CD38 is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Human CD38, His Tag at 1μg/ml (100μl/Well) on the plate. Dose response curve for Anti-CD38 Antibody, hFc Tag with the EC50 of 3.7ng/ml determined by ELISA (QC Test). SPR Data Anti-CD38 Antibody captured on Protein A chip, can bind Human CD38, His Tag with an affinity constant of 0.23μM as determined in a SPR assay (Biacore T200).
Background :
CD38 (cluster of differentiation 38), also known as cyclic ADP ribose hydrolase, is a transmembrane glycoprotein found on the surface of some immune cells including plasma cells, activated or immature T and B cells, monocytes, and natural killer cells. CD38 participates in cell adhesion, signal transduction and calcium signaling.
Synonyms :
ADPRC 1; T10; CD38; ADP-ribosyl cyclase 1; cADPr hydrolase 1; CD38 molecule; EC 2.4.99.20; EC 3.2.2.6
