Antibody DetailsProduct DetailsReactivity Species Mouse Host Species Rat Immunogen E. coli-Derived Recombinant Mouse CCL28 Endotoxin Level <0.1 EU/µg as determined by the LAL method Formulation This monoclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco's phosphate buffered saline (1X PBS) pH 7.2 - 7.3 containing 5.0% w/v trehalose with no calcium, magnesium or preservatives present. Storage and Handling The lyophilized antibody can be stored desiccated at -20°C to -70°C for up to twelve months. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid repeated freeze thaw cycles. No detectable loss of activity was observed after six months. Country of Origin USA Shipping Next Day Ambient RRIDAB_2828497 Applications and Recommended Usage? Quality Tested by Leinco Western Blotting: To detect Mouse CCL28 this monoclonal antibody can be used at a concentration of 1-2 µg/ml. This monoclonal antibody should be used in conjunction with compatible second-step reagents such as PN:R377 and a chromogenic substrate such as PN:T343. The detection limit for Mouse CCL28 is 20 ng/lane under either reducing or non-reducing conditions. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used. Other Applications Reported In Literature ? Neutralization: This antibody is useful for neutralization of Mouse CCL28 bioactivity. The antibody dose required to neutralize 50% (ND50) of the biological activity of Mouse CCL28 (at 2 ng/ml) is 2.5 - 5 µg/ml. Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change. DescriptionSpecificity Rat Anti-Mouse CCL28 (Clone 134306) recognizes an epitope on Mouse CCL28. This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype. Background CCL28, also known as mucosae-associated epithelial chemokine (MEC), CCK1 and SCYA28, is a chemokine. CCL28 regulates the chemotaxis of cells that express the chemokine receptors CCR3 and CCR10. CCL28 is expressed by columnar epithelial cells in the gut, lung, breast and the salivary glands and drives the mucosal homing of T and B lymphocytes that express CCR10, and the migration of eosinophils expressing CCR3.1,2,3 CCL28 is constitutively expressed in the colon, but its levels can be increased by pro-inflammatory cytokines and certain bacterial products implying a role in effector cell recruitment to sites of epithelial injury.3 CCL28 is a key regulator of IgA antibody-secreting cells (ASCs) accumulation in the mammary gland and thus controls the passive transfer of IgA antibodies from mother to infant.4 Antigen DetailsProtein PubMed NCBI Gene Bank ID UniProt.org References & Citations1.
