Active Recombinant Human CD38 Protein, LIgG2b Fc-tagged, low endotoxin

• Cat.No.: CD38-361H
• Product Overview: Recombinant Human CD38 Protein, LIgG2b Fc-tagged, low endotoxin is expressed from human 293 cells (HEK293). It contains AA Val 43 - Ile 300 (Accession # P28907-1). Predicted N-terminus: Val 43. This protein carries a llama IgG2b Fc tag at the C-terminus. The protein has a calculated MW of 57.7 kDa. The protein migrates as 66-90 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

• Bio-activity: Recombinant Human CD38 Protein, LIgG2b Fc-tagged, low endotoxin at 1 μg/mL (100 μL/well) can bind Anti-CD38 MAb, Human IgG1 with a linear range of 0.4-6 ng/mL (QC tested).
• Molecular Mass: 57.7 kDa
• Protein length: Val 43 - Ile 300
• Endotoxin: Less than 0.01 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• Notes: Please avoid repeated freeze-thaw cycles.
• Stability: No activity loss is observed after storage at:
  4-8 centigrade for 12 months in lyophilized state;
  -70 centigrade for 3 months under sterile conditions after reconstitution.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
