| Description | This product is a recombinant Mouse antibody provided by CreativeBiolabs. The antibody is specific for Interleukin 21. It can be used for Interleukin 21 detection in Western Blot, Enzyme-Linked Immunosorbent Assay, Immunofluorescence, Flow Cytometry and Neutralization Assay. It was expressed in mammalian cells (293F or CHO) with antibody encoding genes and purified by affinity chromatography. Each lot of this antibody is quality control tested by SDS-PAGE and SEC-HPLC analysis. For highly sensitive assays, we recommend the ultrapurified form of the product, which has a lower endotoxin limit than standard antibody, less than 1 EU/mg or even 0.1 EU/mg. |
