Anti-LARK antibodies enable researchers to detect and measure the LARK antigen in biological samples. This target is a reported synonym of the RBM4 gene, which encodes RNA binding motif protein 4. This protein is known to function in carbohydrate metabolism and homeostasis and RNA splicing, among other biological roles. The human version of LARK has a canonical amino acid length of 364 residues and a protein mass of 40.3 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include RBM4A and ZCCHC21. Indicated applications for LARK antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
