Cat#: | RP-4065H |
Product Name: | Recombinant Human IL3 Protein, Sf9 |
Synonym: | MCGF (Mast cell growth factor), Multi-CSF, HCGF, P-cell stimulation factor, IL-3, MGC79398, MGC79399. |
Description: | Interleukin-3 Protein produced in insect cells is a single, glycosylated polypeptide chain containing 133 amino acids and having a molecular mass of 15000 Dalton. The IL-3 CSF is fused to a C-terminal His-tag (6x His) and purified by proprietary chromatographic techniques. |
Source: | Insect Cells. |
AA Sequence: | The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Pro-Ala-Pro-Thr. |
Purity: | Greater than 95.0% as determined by(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. |
Bioactivity: | The ED50 as determined by the dose-dependant stimulation of TF-1 cells is < 0.1 ng/ml, corresponding to a Specific Activity of 10,000,000IU/mg. |
Formulation: | Lyophilized from a concentrated (1mg/ml) solution in water containing 0.5X PBS pH-7.4. |
Stability: | Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃ |
Reconstitution: | It is recommended to reconstitute the lyophilized Interleukin-3 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
Storage: | Lyophilized Interleukin-3 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL3 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. |
