2-acetamido-2-deoxy-[alpha]-D-galactosidases of clostridium perfringens. separation and characterization of an exoglycosidase and an oligosaccharidase
(Elsevier, 1978-03)
Two distinct 2-acetamido-2-deoxy-[alpha]-D-galactosidases have been separated from filtrates of cultured Clostridium perfringens by electrophoresis in 6.5% poly(acryl-amide) gels. One of the enzymes had a mobility of ...
2-acetamido-2-deoxy-[alpha]--galactosidases of clostridium perfringens. Separation and characterization of an exoglycosidase and an oligosaccharidase
(Elsevier, 1978-03)
Two distinct 2-acetamido-2-deoxy-[alpha]--galactosidases have been separated from filtrates of cultured Clostridium perfringens by electrophoresis in 6.5 % poly(acryl-amide)gels. One of the enzymes had a mobility of 0.32-0.36 ...
Excitatory amino acidergic pathways and receptors in the basal ganglia
(Springer-Verlag, 1991-10)
The striatum receives the majority of excitatory amino acidergic input to the basal ganglia from neocortical and allocortical sources. The subthalamic nucleus and the substantia nigra also receive excitatory amino acidergic ...
Chemical permeabilization and in situ removal of daidzein from biologically viable soybean (Glycine max) seeds
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1998-09)
After 24 h of chemical permeabilization with 20% (v/v) methanol at 25 °C, the amount of daidzein released from soybean seeds is 15 to 20% of the amount (0.0423 ± 0.0045 mg/g seed dry wt) obtained by physical grinding. With ...
Cell cycle of Chlorella vulgaris can deviate from the synchronous binary division model
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1997-06)
Conditioned medium from high density Chlorella vugaris cultures was freeze dried extracted into ethanol. The ethanol was volatilized and the resulting powder then introduced with C. vulgaris photoautotrophic cultures which ...
Initiation of poly-N-acetyllactosamine chain biosynthesis occurs preferentially on complex multiantennary asparagine-linked oligosaccharides
(Elsevier, 1990-08-01)
An N-acetyl-[beta]--glucosaminyltransferase activity involved in the initiation of poly-N-acetyllactosamine chain biosynthesis can be solubilized from Ehrlich ascites tumor cell microsomal membranes. The ability of this ...
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 ...
Continuous medium perfusion leads to long-term cell viability and oxygen production in high-density photobioreactors
(Kluwer Academic Publishers; Chapman & Hall, London ; Springer Science+Business Media, 1995-11)
A light-emitting diode-based photobioreactor (LED-based PBR) operated in a continuous perfusion mode with a perfusion rate of 3 to 6 reactor volumes a day supports high-density algal cultures, of cell concentrations up to ...
Protein---carbohydrate interaction : Part XXI. The interaction of concanavalin a with d-fructans
(Elsevier, 1969-06)
The immunochemical techniques of quantitative precipitation and hapten inhibition have been employed in a study of the interaction of concanavalin A with several levans of bacterial and plant origin. Of the polysaccharides ...
Protein---carbohydrate interaction. : Part XXII. A chemically-synthesized d-mannan and the interaction of some synthetic d-mannans with concanavalin A
(Elsevier, 1970-06)
1,6-Anhydro-[beta]--mannopyranose was polymerized in the presence of chloroacetic acid. A high-molecular-weight fraction insoluble in 80% ethanol was isolated and studied. Periodate-oxidation studies showed the polymer to ...
