Growth factors & cytokines

Recombinant growth factors and cytokines, low-endotoxin, lot-traced.

Recombinant growth factors, cytokines, chemokines and morphogens, expressed in E. coli, HEK293 or CHO depending on which system gives the correct fold and post-translational state. Every product page names the expression host, the amino-acid range, and the observed mass by SDS-PAGE.

Bioactivity is published as an ED50 with the assay that produced it. Endotoxin is measured by LAL before fill/finish. Proteins are sterile-filtered and lyophilized in their stated buffer, with carrier-free and BSA-carrier details printed on each product page.

Growth factors ship on cold packs by default; the shipping class and lot-specific storage guidance are printed on every product page.
