S100 calcium binding protein A8 (S100-A8), also kown as Cystic fibrosis antigen, Migration inhibitory factor-related protein 8 60B8AG, CAGA, CFAG, CGLA, CP-10, L1Ag, MA387, MIF, MRP8, NIF and P8, 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. Most S100 proteins are disulfide-linked homodimer, and is normally present in cells derived from the neural crest, chondrocytes, macrophages, dendritic cells, etc. S100A8 plays a role in various functions of myeloid cells by forming a heterocomplex with S100A9. S100A8 and S100A9 are known to be overexpressed in certain species of carcinomas. S100A8 may function in the inhibition of casein kinase and as a cytokine. Altered expression of this protein is associated with the disease cystic fibrosis.[1] S100A8 plays an important role in differentiation of thyroid carcinoma possibly by forming a complex with S100A9. S100A8 and S100A9 may also play a key role in inflammation-associated cancer. [2]

Recombinant human S100A8 Protein (rhS100A8), Met 1-Glu 93 (Accession # AAH05928)was expressed in E.coli cell.

Molecular Characterization
rhS100A8 contains no tag and has a calculated MW of 10.8 kDa. In DTT-reduced SDS-PAGE, rhS100A6 protein migrates as predicted.

Less than 1.0 EU per μg of the rhS100A8 by the LAL method.

>95% as determined by SDS-PAGE.

Lyophilized from 0.22 μm filtered solution in PBS, pH 7.4. Normally Mannitol or Trehalose are added as protectants before lyophilization.

See Certificate of Analysis for details of reconstitution instruction and specific concentration.

Avoid repeated freeze-thaw cycles.
No activity loss was observed after storage at:
In lyophilized state for 1 year (4°C-8°C); After reconstitution under sterile conditions for 1 month (4°C-8°C) or 3 months (-20°C to -70°C).
