What does IS stand for?

You can recognize our engineered cytokines by the acronym “IS” in the product name. IS stands for improved sequence. Currently we offer human IL-2, FGF-2, Oncostatin M, PDGF-BB, VEGF, and mouse IL-3 as variants with an improved sequence. These engineered variants guarantee high stability, better solubility during reconstitution and high activity in culture.
