Anti-Ke2 antibodies enable researchers to detect and measure the Ke2 antigen in biological samples. This target is a reported synonym of the PFDN6 gene, which encodes prefoldin subunit 6. This protein is known to function in protein folding and protein stabilization, among other biological roles. The human version of Ke2 has a canonical amino acid length of 129 residues and a protein mass of 14.6 kilodaltons. It is reported to be widely expressed in many tissue types. Ke2 is a member of the Prefoldin subunit beta protein family.
