 Cellular expression of glycoproteins can be evaluated by various molecular biology methods, which include RNA and protein measurements.However, cellular expression of gangliosides, which are sialic acid-containing glycosphingolipids, can not be evaluated by these methods.Instead, it can be measured using anti-glycan antibodies, and despite the large collection of such antibodies in a community resource database, they are not always available for each ganglioside.
