<unk>  is a synonym for the dimeric form of the pyruvate kinase isoenzyme type<unk>  <unk> -PK).<unk>  is a key enzyme within<unk>  metabolism and can be used in stool (fecal) samples for the screening of colorectal<unk> s (= bowel cancer) and in EDTA plasma samples for the follow-up of various cancers.<unk>  is not an organ-specific<unk>  marker, such as PSA. As a biomarker the amount of<unk>  in stool and EDTA-plasma reflects the specific metabolic status of the<unk> s.
Sandwich ELISA’s based on two monoclonal antibodies which specifically recognize<unk>  (the dimeric form of<unk> -PK) are available for the quantification of<unk>  in stool and EDTA-plasma samples respectively.
