> 90% as determined by SDS-PAGE. |
| Storage: |
Store under sterile conditions at -20°C to -80°C. Avoid repeated freeze-thaw cycles. |
| Reconstitution: |
Use distilled water to dissolve the protein to a concentration above 100 μg/mL. Aliquot the solution into single-use vials and freeze. |
| Molecular Mass: |
The recombinant CD19 consists of 283 amino acids and predicts a molecular mass of 31.6 kDa. |
| Stability: |
Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. |
| Endotoxin: |
Less than 1.0 EU per μg as determined by the LAL method. |
| Notes: |
Research Use Only. Not for use in clinical procedures. Aoid repeated freeze-thaw cycles. |
