2-Substituted methyl [alpha]--galactopyranosides: Synthesis and binding affinity for the A and B subunits of the Griffonia simplicifolia I isolectins
(Elsevier, 1985-07-01)
The binding affinities of the N-acetyl, N-trifluoroacetyl, N-propionyl, N-formyl, N-benzoyl, N-p-nitrobenzoyl, N-p-aminobenzoyl, and N-methyl derivatives of methyl 2-amino-2-deoxy-[alpha]--galactopyranoside and the 2-O-acetyl, ...
Transtubular bioreactor: A perfusion device for mammalian cell cultivation
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1989-01)
A transtubular mammalian cell perfusion chamber has been developed that allows separate delivery and control of medium and gas flow to the cells. The hydrodynamic and mass transfer characteristics of the reactor are studied ...
Measurement of ammonia and glutamine in cell culture media by gas sensing electrodes
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1989-04)
This paper describes the use of a commercially available off-line gas sensing electrode for determination of ammonia and glutamine in cell culture media. The measurement technique was tested in different media preparations ...
Structure of a water-insoluble -glucan isolated from a streptococcal organism
(Elsevier, 1983-08-16)
The structure of the extracellular polysaccharide (water-insoluble -glucan) from an anaerobic, Gram-positive coccus organism (Streptococcus) has been investigated. Acid hydrolysis of the methylated glucan yielded 2,3,4,6-tetra-, ...
Isolation and characterization of a glycopeptide from human senescent erythrocytes
(Elsevier, 1983-08-16)
A glycopeptide (called "senescence-factor glycopeptide", SF-G) has been isolated from a tryptic digest of human erythrocytes by specific adsorption and elution from immobilized peanut lectin. SF-G was detectable in old but ...
Production and characterization of antisera raised to the manninotrionate group [[alpha]--Galp-(1-->6)-[alpha]--Galp-(1-->6)--gluconate]
(Elsevier, 1989-06-15)
Manninotrionate [[alpha]--Galp-(1-->6)-[alpha]--Galp-(1-->6)--gluconate] was coupled to bovine serum albumin (BSA), and antisera were raised in rabbits to this carbohydrate--protein conjugate. The antisera were studied ...
Effect of anchorage dependency on growth rate and monoclonal antibody production of hybridoma cells
(Kluwer Academic Publishers; Springer Science+Business Media, 1988-05)
Hybridoma cells (S3H5/γ2bA2) are found to grow either in suspension or as attached to the surface of cell culture T flask. Cell growth rates and monoclonal antibody (MAB) production rates of both suspended and attached ...
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 ...
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 ...
