Anti-CD121b antibodies enable researchers to detect and measure the CD121b antigen in biological samples. This target is a reported synonym of the IL1R2 gene, which encodes interleukin 1 receptor type 2. This protein is known to function in immune response pathways, among other biological roles. The human version of CD121b has a canonical amino acid length of 398 residues and a protein mass of 45.4 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane and is secreted of cells. This target antigen may also be known as CDw121b. Western Blot is the most common application for the CD121b antibodies listed below. ELISA and Immunohistochemistry are also common applications.
