Anti-p19INK4d antibodies enable researchers to detect and measure the p19INK4d antigen in biological samples. This target is a reported synonym of the CDKN2D gene, which encodes cyclin dependent kinase inhibitor 2D. This protein is known to function in the cell cycle and the regulation of cell growth, among other biological roles. The human version of p19INK4d has a canonical amino acid length of 166 residues and a protein mass of 17.7 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells and notably expressed in the testis, nasopharynx, lymph node, fallopian tube, and bone marrow. Other names for this target antigen include INK4D, p19, and p19-INK4D. Immunohistochemistry is the most common application for the p19INK4d antibodies listed below. ELISA and Western Blot are also common applications.
