Used for the quantitative measurement of Glycine Decarboxylase (GLDC) activity in human biological samples such as serum, plasma, and tissue lysates. This ELISA kit enables researchers to assess GLDC enzyme function, which plays a critical role in glycine metabolism and one-carbon pathways. It is widely applied in metabolic disease research, particularly in studies related to glycine encephalopathy (non-ketotic hyperglycinemia) and certain cancers where GLDC expression is dysregulated. The assay supports early diagnosis, monitoring of disease progression, and evaluation of therapeutic interventions targeting metabolic pathways. Its high sensitivity and specificity make it suitable for both clinical laboratories and biomedical research settings.
