||Recombinant Human IL4 (P05112-1) mature form (His 25-Ser 153), fused with with an initial Met, was produced in E. coli.
||Lyophilized from sterile 20mM MES, 200mM NaCl, pH 6.0
||The recombinant human IL4 consisting of 130 amino acids and migrates with an apparent molecular mass of 15 kDa as predicted.
||< 1.0 eu per μg of the protein as determined by the LAL method.
||Samples are stable for up to twelve months from date of receipt at -70oC.
||Store it under sterile conditions at -20oC~-70oC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
||It is recommended that sterile water be added to the vial to prepare a stock solution. Centrifuge the vial at 4oC before opening to recover the entire contents.
