Anti-GRB4 antibodies enable researchers to detect and measure the GRB4 antigen in biological samples. This target is a reported synonym of the NCK2 gene, which encodes NCK adaptor protein 2. This protein is known to function in cell migration and the regulation of cell proliferation, among other biological roles. The human version of GRB4 has a canonical amino acid length of 380 residues and a protein mass of 42.9 kilodaltons. It is reported to be localized in the ER and cytoplasm of cells and widely expressed in many tissue types. Indicated applications for GRB4 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
