Product Description
Recombinant Human Inteleukin-1 Beta 2ug
Description - Leukin-1 beta Human Recombinant produced in
E.Coli is a non-glycosylated, Polypeptide chain containing 153
amino acids and having a molecular mass of 17000 Dalton.
The IL-1b is purified by proprietary chromatographic techniques.
Synonyms - Catabolin, Lymphocyte-activating factor (LAF),
Endogenous Pyrogen (EP), Leukocyte Endogenous Mediator (LEM),
Mononuclear Cell Factor (MCF), IL1F2, IL-1 beta.
Appearance - Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation - The protein was lyophilized from a concentrated (1mg/ml)
sterile solution containing 50mM Phosphate buffer pH=7.1 and 150mM NaCl.
Solubility - It is recommended to reconstitute the lyophilized
Interleukin-1β in sterile 18MO-cm H2O not less than 100µg/ml,
which can then be further diluted to other aqueous solutions.
Stability - Lyophilized Interleukin-1b although stable at room
temperature for 3 weeks, should be stored desiccated below -18 C.
Upon reconstitution IL1b 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 avoid freeze-thaw cycles.
Purity - Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC
(b) Analysis by SDS-PAGE
