Active Recombinant Human S100A8 (Met1-Glu93) and S100A9 (Thr2-Pro114) Heterodimer Protein

• Cat.No.: S100A8/S100A9-13H
• Product Overview: Recombinant human S100A8 (Met1-Glu93) and S100A9 (Thr2-Pro114) Heterodimer protein without tag was expressed in E. coli.

Specification

• Description: The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. This protein may function in the inhibition of casein kinase and as a cytokine. Altered expression of this protein is associated with the disease cystic fibrosis. Multiple transcript variants encoding different isoforms have been found for this gene.
