The Toso ELISA kits listed below utilize specific antibodies for the plate-based assay of Toso in various samples. Toso is another term for the FCMR gene, which encodes the protein, Fc mu receptor in humans. It has been reported that Toso plays a role in the regulation of apoptosis, among other functions. Structurally, the FCMR protein is 390 amino acid residues in length and 43.1 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is known to be a secreted protein. In terms of tissue specificity, it is reported to be expressed in lymph nodes, peripheral blood leukocytes, lung, thymus and kidneys. Other names for this target antigen include FAIM3, FAIM3, and FcmuR. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
