Interaction of linear manno-oligosaccharides with three mannose-specific bulb lectins. Comparison with mannose/glucose-binding lectins
(Elsevier, 1992-05-22)
Three new mannose-binding lectins, isolated from daffodil (NPA), amaryllis (HHA), and snowdrop (GNA) bulbs, are capable of precipitating with a linear mannopentaose (Man[alpha]1-3Man[alpha]1-3Man[alpha]1-3Man[alpha]1-2Man). ...
Use of Cyclodextrin-Cholesterol Complex as a Primary Standard in Cholesterol Analysis
(Elsevier, 1993-06)
Cholesterol is an analyte commonly measured in various biological fluids. Enzymic procedures have virtually replaced the chemical methods for cholesterol determinations. Standardization of cholesterol assays often involve ...
Interaction of five -mannose-specific lectins with a series of synthetic branched trisaccharides
(Elsevier, 1991-06-25)
The interaction of a series of synthetic, branched trisaccharides with five -mannose-specific lectins was studied by precipitation-inhibition assay. The branched methyl [alpha]--mannotrioside, [alpha]--Manp-(1-->3)-[[ ...
Extraction of aminoglycoside antibiotics with reverse micelles
(John Wiley & Sons, Ltd., 1996-01)
The reverse micelle system of sodium di-2-ethylhexyl phosphate was used to extract aminoglycoside antibiotics, neomycin and gentamicin. The aminoglycosides can be efficiently extracted into a reverse micelle solution, and ...
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 ...
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 ...
New mannose-specific lectins from garlic (Allium sativum) and ramsons (Allium ursinum) bulbs
(Elsevier, 1992-05-22)
Two new mannose-binding lectins were isolated from garlic (Allium sativum, ASA) and ramsons (Allium ursinum, AUA) bulbs, of the family Alliaceae, by affinity chromatography on immobilized mannose. The carbohydrate-binding ...
