Anti-MAPK 4 antibodies enable researchers to detect and measure the MAPK 4 antigen in biological samples. This target is a reported synonym of the MAPK4 gene, which encodes mitogen-activated protein kinase 4. This protein is known to function in the cell cycle and intracellular signal transduction, among other biological roles. The human version of MAPK 4 has a canonical amino acid length of 587 residues and a protein mass of 65.9 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells. Other names for this target antigen include ERK-4, ERK4, and PRKM4. Indicated applications for MAPK 4 antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
