| 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. |

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. |
