This gene encodes the folylpolyglutamate synthetase enzyme. This enzyme has a central role in establishing and maintaining both cytosolic and mitochondrial folylpolyglutamate concentrations and, therefore, is essential for folate homeostasis and the survival of proliferating cells. This enzyme catalyzes the ATP-dependent addition of glutamate moieties to folate and folate derivatives. Alternative splicing results in transcript variants encoding different isoforms.Store at -20°C or lower. Aliquot to avoid repeated freezing and thawing. *   http://www.creative-diagnostics.com/Anti-FPGS-PAb-189299-147.htm
