Product Description
Recombinant Human IL-1 Receptor Antagonist 50ug
Description - IL1 ra Human Recombinant produced in E.Coli is a non-glycosylated,
N-terminal methionyl form of the human naturally-occurring
polypeptide chain containing 153 amino acids and having a molecular
mass of 17000 Dalton. The IL1ra is purified by proprietary chromatographic techniques.
Appearance - Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation - Lyophilized protein with no additives.
Solubility - It is recommended to reconstitute the lyophilized Interleukin
1ra in sterile 18Mω-cm H2O not less than 100µg/ml, which can
then be further diluted to other aqueous solutions.
Stability - Lyophilized Interleukin 1ra although stable at room temperature for
3 weeks, should be stored desiccated below -18 C. Upon reconstitution
IL-1ra 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).
Purity - Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis byn SDS-PAGE.
