IL 1 alpha Protein

• Catalog Number: orb429398
• Category: Tools
• Description: Recombinant of IL 1 alpha protein
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Purity: Greater than 98.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
• Solubility (25°C): It is recommended to reconstitute the lyophilized Interleukin 1a in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
• Protein Sequence: The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Pro-His-Ser-Phe
• Source: Escherichia Coli
• Biological Activity: The ED50 as determined by the dose-dependant stimulation of murine D10S cells is < 0.005 ng/ml, corresponding to a Specific Activity of 200,000,000IU/mg.
• Storage: Stability: Lyophilized Interleukin-1a although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL1A 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
• Buffer/Preservatives: The protein was lyophilized from a concentrated (1mg/ml) sterile solution containing 50mM Tris-HCl, pH=8.
• Alternative names: Hematopoietin-1, Lymphocyte-activating factor (LAF
• Note: For research use only
• Application notes: Cytokines And Growth Factors
• Expiration Date: 12 months from date of receipt.
