[alpha]-(2 --> 3)- and [alpha]-(2 --> 6)-Sialyltransferase activities present in three variants of Ehrlich tumor cells: identification of the products derived from N-acetyllactosamine and [beta]--Gal-(1 --> 3)-[alpha] GalNAc-(1 --> O)-Bn
(Elsevier, 1994-11-01)
We compared several sialyltransferase activities related to synthesis of O-linked and N-linked sialylglycoproteins in Ehrlich ascites tumor cells that grow normally in murine ascites, but are not adherent nor grow in tissue ...
Control of gene expression at the level of translation initiation
(Elsevier, 1994-10)
Protein synthesis is controlled at the level of translation initiation. Cells rapidly respond to environmental changes by disassembly of polysomes and recruitment of specific mRNAs from inactive ribonucleoprotein particles ...
Synthesis of N-acetyllactosamine containing a -[6-3H]galactopyranosyl group
(Elsevier, 1984-07-01)
A simple and convenient method for the introduction of radiolabel onto C-6' of N-acetyllactosamine is described. 1-N-Benzyl-3-O-[beta]--galactopyranosyl--arabinosylamine (1) was synthesized from 3-O-[beta]--galactopyrano ...
N,N'-diacetylchitobionic N-alkylamides: Synthesis, and interaction with two 2-acetamido-2-deoxy--glucose-binding lectins
(Elsevier, 1981-10-16)
Condensation of N,N'-diacetylchitobiono-1,5-lactone, obtained by oxidation of N,N'-diacetylchitobiose, with n-alkylamines gave N,N'-diacetylchitobionic N-alkylamides. The interaction of these glycolipids with wheat-germ ...
Immunochemical studies on the combining site of the blood group A-special lima bean lectin
(Elsevier, 1986-08-15)
The combining site of the lima bean (Phaseolus lunatus) lectin (LBL) was studied by quantitative precipitin and precipitin-inhibition assays. The lectin precipitated best with hog gastric mucosa and human ovarian cyst blood ...
The effect of glycosidases on the survival of rat erythrocytes in circulation
(Elsevier, 1988-07-15)
Enzymic removal of sialyl groups from mammalian erythrocytes resulted in their rapid sequestration from circulation subsequent to autologous transfusion. It has been demonstrated by many investigators that the terminal ...
Chemical synthesis of p-nitrophenyl [beta]-sophoroside and p-nitrophenyl [beta]-laminarabioside
(Elsevier, 1969-10)
Condensation of tetra-O-acetyl-[alpha]--glucopyranosyl bromide with p-nitrophenyl 4,6-O-benzylidene-[beta]--glucopyranoside followed by appropriate deblocking reactions gives rise to an approximately equimolar mixture of ...
Carbohydrate-binding properties of an immobilized [alpha]--galactopyranosyl-binding protein (lectin) from the seeds of Bandeiraea simplicifolia
(Elsevier, 1976-03)
The [alpha]--galactopyranosyl-binding lectin from Bandeiraea simplicifolia has been coupled to cyanogen bromide-activated Sepharose 4B. Using this immobilized system, we have been able to study the interaction of the lectin ...
Synthesis of [alpha]- and [beta]-glycosides containing spin labels, as probes for studies of carbohydrate-protein interaction
(Elsevier, 1981-03-02)
Nitroxide spin-labeled [alpha]--glycopyranosides were synthesized in good yield and in a highly stereoselective manner by reaction of per-O-benzyl-[alpha]--glycopyranosyl bromides with 2,2,6,6-tetramethyl-4-piperidinol ...
