Isolation and characterization of a second lectin (SNA-II) present in elderberry (Sambucus nigra L.) bark
(Elsevier, 1990-03)
A second lectin (SNA-II) has been isolated from elderberry (Sambucus nigra L.) bark by affinity chromatography on immobilized asialo-glycophorin. This lectin is a blood group nonspecific glycoprotein containing 7.8% ...
A quantitative dot-blot immunoassay for integral membrane proteins: Preparation of pancreatic plasma membranes containing apical and basolateral domains
(Elsevier, 1991-01)
Modifications of standard dot-blot immunoassay techniques have been made for the quantitation of integral membrane protein antigens. The modification involves the signal development step, which is performed by using ...
Hadamard transform photothermal deflection desitometry of electrophretically blotted proteins
(Elsevier, 1990)
Hadamard transform spatial multiplexing techniques are applied to laser densitometry in order to prevent the photo-induced degradation of sensitive materials. Photochemical and thermal degradations can often occur in point ...
Discordant changes in plasma ACTH and [beta]-lipotropin/[beta]-endorphin levels in Clshing's disease patients with depression
(Elsevier, 1992-11)
Cushing's Disease is often associated with a depressive syndrome, with mood, vegetative, and cognitive abnormalities of variable severity. In 11 patients with (pituitary ACTH-dependent) Cushing's disease (10 women, 1 man), ...
α- d -Galactosylation of surface fucoglycoconjugate(s) upon stimulation/activation of murine peritoneal macrophages
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1992-04)
Murine resident macrophages express, on their surface, carbohydrate epitopes which undergo changes during their stimulation/activation as monitored by binding of 125 I labelled Evonymus europaea and Griffonia simplicifolia ...
A double-blind, placebo-controlled study of the effect of imipramine on TRH-induced urinary urgency in healthy men
(Elsevier, 1992)
We studied the effect of imipramine (IMI) on thyroid releasing hormone (TRH)-induced urinary urgency as a way of investigating the mechanism of the beneficial effect of IMI on enuresis. In a double-blind study, 12 normal, ...
Regulation of Chemokine Production by the Oxidative Metabolism of L-Arginine in a Human Mixed Lymphocyte Reaction
(Elsevier, 1994-06)
Previous studies have shown that during the development of a mixed lymphocyte reaction (MLR) levels of the chemotactic cytokines IL-8 and MCP-1 (members of the C-X-C and C-C supergene families, respectively) increase in a ...
Antibody-antigen complex formation with immobilized immunoglobulins
(Elsevier, 1992-08-15)
We have investigated the complex formation between an immobilized monoclonal antibody and antigens that differ in size about 50-fold. As a model system, we used an iodinated progesterone derivative and a progesterone-horseradish ...
Carbohydrate-binding specificity of the daffodil (Narcissus pseudonarcissus) and amaryllis (Hippeastrum hybr.) bulb lectins
(Elsevier, 1990-06)
The carbohydrate binding specificity of the daffodil (Narcissus pseudonarcissus; NPA) and amaryllis (Hippeastrum hybr.; HHA) lectins, isolated from extracts of their bulbs by affinity chromatography on immobilized mannose, ...
