Secretin: specific binding to rat brain membranes.
The binding of [125I]secretin to rat brain membranes was investigated. Radiolabeled secretin bound with high affinity (KD = 0.2 nM) to a single class of noninteracting sites. Binding was specific, saturable, and reversible. Regional distribution studies indicated that the specific binding was greatest in the cerebellum, intermediate in the cortex, thalamus, striatum, hippocampus, and hypothalam...
متن کاملBomebesin: specific binding to rat brain membranes.
The binding of a radiolabeled bomebesin analogue to rat brain membranes was studied. [125I-Tyr4]Bombesin bound with high affinity (KD = 3 nM) to a single class of non-interacting sites. Binding was specific, saturable (3.8 pmol of sites/g of wet tissue), and reversible. Regional and subcellular distribution studies showed that the density of sites was 7-fold greater in the hippocampus than the ...
متن کاملSpecific binding of human corticosteroid-binding globulin to cell membranes.
Specific binding sites for corticosteroid-binding globulin were detected on membranes prepared from human prostates. The binding sites are typical of membrane receptors: they are saturable and specific and have high affinity. There was little specific binding at 4 degrees C and 23 degrees C. Maximal specific binding was obtained at 37 degrees C. Scatchard analysis revealed the presence of a sin...
متن کاملVasoactive intestinal polypeptide: specific binding to rat brain membranes.
The binding of radiolabeled vasoactive intestinal polypeptide (VIP) to rat brain membranes was investigated. Specific binding of 125I-labeled VIP was reversible and saturable (Bmax = 2.2 pmol/g of wet tissue). Brain membranes exhibited a high affinity for 125I-labeled VIP (KD = 1 nM) at a single class of noninteracting sites. Binding of 125I-labeled VIP paralleled its immunohistochemical locali...
متن کاملSpecific binding of proinsulin C-peptide to human cell membranes.
Recent reports have demonstrated beneficial effects of proinsulin C-peptide in the diabetic state, including improvements of kidney and nerve function. To examine the background to these effects, C-peptide binding to cell membranes has been studied by using fluorescence correlation spectroscopy. Measurements of ligand-membrane interactions at single-molecule detection sensitivity in 0.2-fl conf...
