Interaction of [alpha]2-macroglobulin with trypsin, chymotrypsin, plasmin, and papain
(Elsevier, 1983-02-15)
The interaction [alpha]2-macroglobulin with four proteinases has been investigated by binding assays and by gel electrophoresis. At pH 7.65 the binding ratios of the proteinase-[alpha]2-macroglobulin complexes were found ...
On-line multichannel Raman spectroscopic detection system for capillary zone electrophoresis
(Elsevier, 1991)
An on-line multichannel Raman spectroscopic detection system for capillary zone electrophoresis using a charge-coupled device as the detector is described. Resonant, near-resonant and non-resonant excitation Raman ...
Percolative versus homogenous energy transport kinetics: time-resolved donor and acceptor fluoresence of isotopic mixed naphthalene crystals
(Elsevier, 1982-04-16)
Tune-resolved spectral studies of the singlet exciton transport threshold in doped naphthalene-perdeuteronaphthalene mixed crystals are presented. While a homogeneous kinetic model adequately explains many of the results, ...
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, ...
The effects of footshock stress on regional brain dopamine metabolism and pituitary [beta]-endorphin release in rats previously sensitized to amphetamine
(Elsevier, 1987-07)
The repeated intermittent administration of amphetamine (AMP) produces an enduring enhancement in the response of dopamine (DA) systems in the brain to a subsequent "challenge" with amphetamine. However, former amphetamine ...
The cluster-tray method for rapid measurement of solute fluxes in adherent cultured cells
(Elsevier, 1981-08)
The use of an inexpensive and simple modification of Costar 24-well cluster trays is described in a rapid and reproducible method for measuring substrate fluxes in adherent cultured eukaryotic cells.
The faradaic admittance of electrochemical processes : III. The frequency dependence
(Elsevier, 1961)
Recent experimental studies have demonstrated the inadequacy of proposed equations for the faradaic admittance, particularly in respect to the frequency dependence. Existing treatments of the faradaic admittance can give ...
Linearized embedding: A new metric matrix algorithm for calculating molecular conformations subject to geometric constraints
(John Wiley & Sons, Inc., 1989-10)
There are many methods in the literature for calculating conformations of a molecule subject to geometric constraints, such as those derived from two-dimensional NMR experiments. One of the most general ones is the EMBED ...
CCK antagonists reveal that CCK-8 and JMV-180 interact with different sites on the rat pancreatic acinar cell CCKA receptor
(Elsevier, 1994)
The ability of CCKA antagonists to inhibit full and partial CCK agonists of the rat pancreatic acinar cell CCKA receptor has been studied. When isolated rat pancreatic acini were superfused with CCK-8 (10 pM-1 nM) or CCK-4 ...
