Interaction of pneumococcal S-14 polysaccharide with lectins from Ricinus communis, Triticum vulgaris, and bandeiraea simplicifolia
(Elsevier, 1977-09)
Two purified lectins, namely, wheat-germ agglutinin (from Triticum vulgaris) and the hemagglutinin from Ricinus communis seeds, readily form a precipitate with pneumococcal S-14 polysaccharide, whereas the Bandeiraea ...
A further investigation of the stannic chloride-catalyzed condensation reaction of 1-hexene and 1,2,3,5-tetra-O-acyl-[beta]--ribofuranoses
(Elsevier, 1983-04-16)
The reaction of 1-hexene with either 1-O-acetyl-2,3,5-tri-O-benzoyl-[beta]--ribofuranose (5b) or 1,2,3,5-tetra-O-acetyl-[beta]--ribofuranose (5a) in the presence of stannic chloride leads to the formation of a complex ...
Equilibrium dialysis and carborydrate-binding studies on the 2-acetamido-2-deoxy--glucopyranosyl-binding lectin from bandeiraea simplicifolia seeds
(Elsevier, 1978-03)
The carbohydrate-binding specificity of Bandeiraea simplicifolia lectin II (BS II lectin) has been studied by quantitative precipitin and hapten-inhibition analysis. The BS II lectin precipitated biopolymers having nonreducing ...
[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 ...
Techniques for preparing hydrogel membrane capsules
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1988-12)
Techniques for preparing four kinds of hydrogel membrane capsules are described. In the present process the material being encapsulated remains in its original environment in an aqueous suspension. Also, capsule characteristics ...
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 ...
Effect of calcium chloride treatment on hybridoma cell viability and growth
(Kluwer Academic Publishers; Springer Science+Business Media, 1992-10)
In order to minimize hybridoma cell damage during calcium alginate entrapment, the effect of calcium chloride treatment on hybridoma cell viability and growth was studied in terms of calcium chloride concentration and ...
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 ...
Effect of mechanical agitation on hybridoma cell growth
(Kluwer Academic Publishers; Springer Science+Business Media, 1988-09)
Hybridoma cells (S3H5/γ2bA2) were grown in spinner flasks at different agitation speeds. It was found that cells in stationary and decline phases of growth were sensitive to shear force caused by agitation but cells in ...
