S100A9 Antibody [Unconjugated]

Western blot shows lysate of mouse lung tissue. PVDF membrane was probed with 0.2 µg/mL of Goat Anti-Mouse S100A9 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2065) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for S100A9 at approximately 14 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

S100A9 was detected in immersion fixed XB2 mouse teratoma keratinocyte cell line using 10 µg/mL Goat Anti-Mouse S100A9 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2065) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; NL001) and counte-rstained with DAPI (blue).

S100A9 was detected in immersion fixed mouse splenocytes using Goat Anti-Mouse S100A9 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2065) at 5 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cell surfaces and cytoplasm. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Background

S100A9, also known as calgranulin B, migration inhibitory factor-related protein 14 (MRP14), belongs to the S100 family of calcium binding proteins of the EF-hand type. It is highly expressed in myeloid cells and other cell types including keratinocytes, epithelial cells and endothelial cells. S100A9 is a cytosolic protein that can also be released into the extracellular milieu. It is associated with various inflammatory diseases.

FAQs for S100A9 Antibody (AF2065). (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.
