Interleukins

IL superfamily is a large group of cytokines, including proteins known as interleukins and interleukin receptors. Members of this superfamily play pivotal roles in diverse biological processes such as immunity, inflammation, and hematopoiesis. Subgroups within the interleukin superfamily include the IL-1, IL-6, IL-10, IL-12, and IL-17 subfamilies, along with additional interleukins and receptors.

Recombinant human BMP-4 protein (Qk038) image

Bioactivity of recombinant BMP-4 protein was determined by a luciferase assay. Qkine E. coli expressed BMP-4 (Qk038, green) has a higher bioactivity (EC50 = 19.4 pM) than alternative BMP-4 expressing in mammalian cells (Supplier A, blue, EC50=133.5 pM) or E. coli (Supplier B, black, EC50 = 43.9 pM).

All our proteins are equally or more bioactive than those from other dominant suppliers

At Qkine, we test and validate the biological activity of all our growth factors against other suppliers’ proteins to ensure that we provide you with the highest level of biological activity.

Bioactivity comparison between leading suppliers shows Qk038 animal origin-free BMP-4 (expressed in E. coli) has a higher bioactivity than microbial and mammalian expressed BMP-4 from alternative suppliers.

All our proteins adhere to the Nine-point Qkine Quality Commitment
