Purification of the pancreatic cholecystokinin receptor
(Elsevier, 1989-03)
We have previously shown that the pancreatic cholecystokinin (CCK) receptor can be solubilized in 1% digitonin. In this study, digitonin-solubilized CCK receptors from rat pancreas were purified using sequential affinity ...
Characterization of a transport system for anionic amino acids in human fibroblast lysosomes
(Elsevier, 1989-12-28)
-Aspartate and -glutamate are transported into human fibroblast lysosomes by a single, low Km, Na+-independent transport system, which has been provisionally named lysosomal system d. This system resembles the Na+-dependent ...
Purification, properties, and oxygen reactivity of p-hydroxybenzoate hydroxylase from Pseudomonas aeruginosa
(Elsevier, 1989-12-21)
The monooxygenase, p-hydroxybenzoate hydroxylase (4-hydroxybenzoate, NADPH: oxygen oxidoreductase (3-hydroxylating), EC 1.14.13.2) has been isolated and purified from Pseudomonas aeruginosa. The reaction catalysed is linked ...
Synthesis and reactivity of open-chain and cyclic 2-cyano zinc and copper organometallics
(Elsevier, 1989)
Various open-chain and cyclic [beta]-cyano zinc and copper organometallics can be prepared by the reaction of the corresponding organic halides with zinc and subsequent transmetalation with CuCN [middle dot] 2 LiCl. They ...
Fluorescence yield near edge spectroscopy of [pi]-bonded CO on Fe(100)
(Elsevier, 1989-12-03)
Near edge X-ray absorption fine structure (NEXAFS) spectra of CO adsorbed on the Fe(100) surface are reported. Spectra, obtained by fluorescence yield (FYNES), are presented for each of the four individual CO adsorption ...
A solid-phase enzyme-linked assay for vitamin B 12
(Springer-Verlag, 1989-01)
A new solid-phase enzyme-linked competitive binding assay for vitamin B 12 (cyanocobalamin) is described. The assay is based on the competition between analyte B 12 molecules and a glucose-6-phosphate dehydrogenase-vitamin ...
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 ...
Monomer-addition growth with a slow initiation step: A growth model for silica particles from alkoxides
(Elsevier, 1989-10-01)
A simplified monomer-addition model with a first-order activation step is developed to describe the dynamics of growth of silica particles from alkoxides. In the limit of slow hydrolysis, we obtain expressions for the ...
