Application

D-(+)-Galactose (D-Gal) is a component with glucose of the disaccharide lactose. Galactose may be used in studies on galactose metabolism as the substrate for indentificaiton, differentiation and characterization of enzymes such as galactose oxidase(s) (GO), galactose permease(s), galactose kinase(s), and galactose phosphorylase(s). D-Gal is used in the study of Maillard glycation and its consequences in vivo.

Other Notes

Specifically inhibits agglutination of mouse spleen lymphocytes by soybean agglutinin

Transformation of mouse-spleen lymphocytes in the presence of soybean agglutinin is markedly enhanced after their treatment with neuraminidase (EC 3.2.1.18). Incubation of the cells with the enzyme also facilitates their agglutination by the lectin. The soybean agglutinin-induced agglutination and transformation

Entamoeba histolytica (Eh) is an extracellular protozoan parasite of the human colon, which occasionally breaches the intestinal barrier. Eradicating ameba that invades is essential for host survival. A defining but uncharacterized feature of amebic invasion is direct contact between ameba

Glycosylation of biopharmaceuticals can mediate cell specific delivery by targeting carbohydrate receptors. Additionally, glycosylation can improve the physico-chemical (drug-like) properties of peptide based drug candidates. The main purpose of this study was to examine if glycosylation of the peptide enkephalin

Constitutively active MYC and reactivated telomerase often coexist in cancers. While reactivation of telomerase is thought to be essential for replicative immortality, MYC, in conjunction with cofactors, confers several growth advantages to cancer cells. It is known that the reactivation

Multifunctional nanocomplexes (NCs) consisting of urocanic acid-modified galactosylated trimethyl chitosan (UA-GT) conjugates as polymeric vectors, poly(allylamine hydrochloride)-citraconic anhydride (PAH-Cit) as charge-reversible crosslinkers, and vascular endothelial growth factor (VEGF) siRNA as therapeutic genes, were rationally designed to simultaneously overcome the extracellular
