IL-1RA Protein

Description:
|Introduction Interleukin-1 ra is a me|Met-Arg-Pro-Ser-Gly. Predicted molecular mass: 17258 Dalton. The ED50 as determined by the dose-dependant inhibition of IL-1 stimulation of D10S cells was found to be 0.5 ug/ml, corresponding to a Specific Activity of 2.0 x 106 IU/mg. Purity: > 95% by RP-HPLC and reducing SDS-|Lyophilized from a 0.2 um filtered solution of 50 mM Tris-HCl, 200 mM NaCl, pH 7.5. Reconstitution: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 ug/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. Shipping: The product is shipped at a|Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70°C as supplied. 1 month, 2 to 8°C under sterile conditions after reconstitution. 3 months, -20 to -70°C under sterile conditions after reconstitution. |Other IL-1RA Proteins: Reco|IL-1ra Monoclonal Antibody |IL-1RA ELISA Kits: Human IL-1RA ELISA Kit
