Anti-MKK1 antibodies enable researchers to detect and measure the MKK1 antigen in biological samples. This target is a reported synonym of the MAP2K1 gene, which encodes mitogen-activated protein kinase kinase 1. This protein is known to function in Bergmann glial cell differentiation and chemotaxis, among other biological roles. The human version of MKK1 has a canonical amino acid length of 393 residues and a protein mass of 43.4 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane, nucleus, and cytoplasm of cells and notably expressed in many tissues, such as the appendix, urinary bladder, and adrenal gland. Other names for this target antigen include CFC3, MAPKK1, and MEK1. Western Blot is the most common application for the MKK1 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
