Modeling of immunosensors under nonequilibrium conditions : II. Experimental determination of performance characteristics
(Elsevier, 1991-08-01)
In an attempt to optimize immunosensors operating with an immobilized antibody as binding protein and an analyte-enzyme conjugate as signal generator that is significantly larger in molecular size than the analyte, in a ...
Charge-coupled device imaging of rapid calcium transients in cultured arterial smooth muscle cells
(Elsevier, 1990)
Transient changes in the concentration of intracellular free calcium are associated with the transduction of primary signals and the subsequent employment of Ca2+ as a second messenger in a multitude of cell types. These ...
The aggregation and dissociation properties of a low molecular weight mannose 6-phosphate receptor from bovine testis
(Elsevier, 1990-11-15)
The aggregation state of low molecular weight mannose 6-phosphate receptor from bovine testis was determined in membrane preparations and in purified soluble preparations. The effect of aggregation on binding of the receptor ...
Callitachykinin I and II, two novel myotropic peptides isolated from the blowfly, Calliphora vomitoria, that have resemblances to tachykinins
(Elsevier, 1994)
Two peptides, related to the locust myotropic peptides locustatachykinin I-IV, were isolated from the blowfly Calliphora vomitoria. Whole, frozen flies were used for extraction with acidified methanol. A cockroach hindgut ...
A model of glucocorticoid receptor unfolding and stabilization by a heat shock protein complex
(Elsevier, 1992-03)
It has recently been reported that incubation of avian progesterone receptors, mouse glucocorticoid receptors, or the viral tyrosine kinase pp60src with rabbit reticulocyte lysate reconstitutes their association with the ...
Purification and carbohydrate-binding specificity of Agrocybe cylindracea lectin
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1997-01)
A lectin was isolated from fruiting bodies of Agrocybe cylindracea by two ion-exchange chromatographies and gel filtration on Toyopearl HW55F. The lectin was homogeneous on polyacrylamide gel electrophoresis and its molecular ...
Synthesis of 4-Amino-1-([beta]-D-ribofuranosyl)pyrrolo[2,3-d]pyridazine; an entry into a novel series of adenosine analogs
(Elsevier, 1991)
The synthesis of a novel adenosine analog, 4-amino-1-([beta]-D-ribofuranosyl)pyrrolo[2,3-d]pyridazine, has been accomplished using pyrrole nucleoside precursors.
Studies of the action of ceramide-like substances ( d - and l -PDMP) on sphingolipid glycosyltransferases and purified lactosylceramide synthase
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1996-06)
We have studied the effects of D -threo-1-phenyl-2-decanoylamino-3-morpholino-1-propanol ( D -PDMP) and its L -enantiomer on glycosphingolipids in cultured normal human kidney proximal tubular cells. We found that D -PDMP ...
Isolation and characterization of a Forssman antigen-binding lectin from velvet bean ( Mucuna derringiana ) seeds
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1994-10)
A Forssman antigen (GalNAcα1-3GalNAcβ1-3Galα1-4Galβ1-4Glcβ1-1Cer)-binding lectin has been purified from velvet bean ( Mucuna derringiana ) seeds by a combination of affinity chromatography and reversed phase HPLC. This ...
