Background

S100-A9, also known as Calgranulin B, belongs to the S100 family containing EF-hand type Ca2+-binding proteins. It is involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation, and associated with the disease cystic fibrosis. S100A9 has been implicated in the abnormal differentiation of myeloid cells in the stroma of cancer. This protein may function in the inhibition of casein kinase. Recombinant S100A9 protein, fused to His-tag at C-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.

FAQs for S100A9 Recombinant Protein (NBP1-44500). (Showing 1 - 2 of 2 FAQs).

1. Have any of your S100A9 antibodies been tested for use in neutralization, or blocking assays, on human samples?
   • Unfortunately at this time we have not tested, or received customer feedback on our S100A9 antibodies for use in blocking or neutralizing assays. If you were planning on testing any of our S100A9 antibodies for neutralizing or blocking capabilities, we would recommend our Innovator’s Reward Program. Under the terms of this program we would be happy to provide a credit for a free vial in exchange for new data on this previously untested or reported application. Please submit this data in the form of an online review. Additional <a href="http://www.novusbio.com/support/innovators-reward.html" target="_self">Innovators Reward Program</a> information can be found using this link.
2. We would like to stain paraffin embedded human intestinal tissue for Calprotectin. One question will be which cells express the majority of Calprotectin - invading neutrophils vs epithelium for example. The antibody list you provide is quite extensive. Which antibody would you recommend for our purpose? Which tissue would you recommend as positive control.
   • Nine of our antibodies to Calprotectin have been validated for IHC-P with human tissue, and you can see all of these products. A number of our IHC images were generated using human spleen samples, and as such this may be a good choice of a positive control tissue. We do sell a human spleen slide product, which is suitable for IHC-P. Unfortunately I do not have an in-depth knowledge of Calprotectin, however the image shown for our antibody with catalogue number NBP1-02826 demonstrates clear staining of neutrophils. The following paper also suggests that the protein is abundant in neutrophils: PMID 11435495.
