Sialic acids are important for cell-cell recognition and cell-pathogen interactions. They can be found on gangliosides localized to plasma membranes, where sialylated sugar chains protrude out of cells, serving as specific antigens in immune reactions and ligands for receptors in cell adhesion.1 N-acetylneuraminic acid (NeuAc) and its hydroxylated form, N-glycolyneuraminic acid (NeuGc), are the two major variants of sialic acid found in most mammals.2Though NeuGc is found in most mammals, its presence in humans is limited due to a partial truncation of the CMP-NeuAc hydroxylase gene that renders the biosynthetic enzyme inactive.3 Therefore, human cells are not capable of synthesizing their own NeuGc-sialoconjugates.4 Despite zero to minimal amounts of NeuGc being found in healthy human tissues, higher levels of NeuGc have been detected in a variety of tumors and are associated with their progression and metastasis.5,6 For example, abnormal expression of N-glycolyl GM3, a NeuGc-containing ganglioside, is found mostly on the surface of malignant tumors.7 Thus, the presence of these tumor-associated antigens provides a basis for early (and potentially pre-malignant) immunological localization and diagnosis. Matreya’s scientists have developed a high-quality standard for N-glycolyl GM3 detection to advance this research quantitative isolation and analysis
