The Recombinant Human IL-3, Animal-Free Protein from R&D Systems is derived from E. coli. The Recombinant Human IL-3, Animal-Free Protein has been validated for the following applications: Bioactivity.

IL-3

Proteins and Enzymes

Lyophilized from a 0.2 ╡m filtered solution in PBS.

Unconjugated

>97%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie« Blue Staining.

Human

15 kDa

IL3

Measured in a cell proliferation assay using TF-1 human erythroleukemic cells. Kitamura, T. et al . (1989) J. Cell Physiol. 140 :323. The ED50 for this effect is 0.02-0.1 ng/mL. The specific activity of recombinant human IL-3 is 1.7 x 106 IU/mg, which is calibrated against the human IL-3 WHO International Standard (NIBSC code: 91/510).

<0.10 EU per 1 ╡g of the protein by the LAL method.
