Background
Human S100A9 (also MRP-14, Calgranulin-B, and p14) is a 14 kDa member of the S100 family of EF-hand calcium-binding proteins. It is 114 amino acids (aa) in length and contains short sequential modules. There is an N-terminal helical region, followed by a calcium-binding EF-hand domain, two more helical regions, a second EF-hand domain, and three additional helical regions. S100A9 will noncovalently heterodimerize with S100A8. In the presence of calcium, this heterodimer will form a heterotetramer. S100A9 is expressed in granulocytes, monocytes, and macrophages during acute and chronic inflammation. Human S100A9 shares 62% and 57% aa identity with rat and mouse S100A9, respectively.
FAQs for S100A9 (DY2065). (Showing 1 - 2 of 2 FAQs).
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.

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.
