Witryna21 kwi 2014 · ( E) Islet perifusion assays on islets from 9-wk-old control ( n = 3) and mutant ( n = 3) littermates show abnormally enhanced insulin secretion in response to a glucose ramp (0–25 mM). The area below the curve was calculated for insulin release tracks and is plotted in the insert. Witryna23 sty 2024 · Batches of 50 mouse islets were stimulated with glucose in presence or absence of 10 nmol/L GLP-1 (7–36)-amide (Bachem, Torrance, CA) as indicated. This assay was performed as reported previously ( 10) with secreted insulin in perifusate fractions determined by radioimmunoassay (kit from Linco Research, St. Charles, MO).
Witryna1 paź 2024 · For islet perifusion assays, ferret islets in a closed small-volume chamber were equilibrated by perfusion with 1.67 mM glucose/KRB at 38.5°C for 30 minutes. The medium used for both static and perifusion assays was identical. First- and second-phase insulin secretion was assessed after a step change to 16.7 mM glucose. WitrynaIslets could be maintained in the perifusion apparatus and continued to respond to glucose for up to 3 h. At minimal financial cost and technical expertise, this apparatus …
