Overview
- Species: Human
- Keywords: Cytokines
- Product Type: Interleukin
- Donor / Source:Escherichia Coli.
- Formulation:IL-1 β was lyophilized from a concentrated (1mg/ml) sterile solution containing 50mM Phosphate buffer pH=7.1 and 150mM NaCl.
- Purity:Greater than 98.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
- Amino acid sequence:The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Pro-Val-Arg-Ser.
- Solubility:It is recommended to reconstitute the lyophilized Interleukin-1β in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
- Stability:Lyophilized Interleukin-1β although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL-1 β 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.
