2023
The microplate reader is a multimodal instrument that allows for a variety of experiments to be performed and measured simultaneously. Microplate readers can make absorbance, fluorescence and luminescence measurements. Multiwell plates are integral to the microplate reader and allow for many experiments to be performed at once. Regardless of the assay type, experiments on the plate reader utilize a standard curve to determine the experimental values. This curve uses samples of known...

This video describes the protocol for grafting human pancreatic islets into the anterior chamber of the mouse’s eye to monitor revascularization of human islet grafts in vivo. It also helps to understand the contribution of recipient versus donor cells in promoting the encapsulation and vascularization of the graft.

Pancreatic Islets Isolation through Collagenase Perfusion: An Enzymatic Method to Isolate Pancreatic Islet Cells

2023
Pancreatic islets, also called the Islets of Langerhans, are a cluster of endocrine cells which produces hormones for glucose regulation and other important biological functions. This protocol explains a method for isolating pancreatic islets by first perfusing collagenase via Ampulla of Vater to digest the exocrine pancreatic tissue and a simplified density gradient centrifugation to purify the islets from mice.

In this video, we describe a procedure to infuse pancreatic islet cells into the hepatic portal vein, followed by application of gel foam to successfully prevent bleeding. Postoperative bleeding is a common cause of high mortality during islet transplantation.
FAQs
Retention relies on the physical arrangement of defined microwells, which holds islets in separate, localized positions after they enter the plate. This arrangement keeps the islets from remaining freely dispersed throughout the sample and supports controlled handling. As a result, researchers can work with positioned islets during observation, culture, or subsequent testing.
Defined microwells place individual islets in a more standardized format than dispersed-sample handling alone. Consistent positioning helps researchers compare islet viability, morphology, and glucose-stimulated insulin secretion under the same general plate-based arrangement. This reduces variation associated with locating and handling dispersed islets and supports more reproducible measurements across analyses.
After islets are physically retained, excess medium and smaller debris can be removed while the islets remain localized in their microwells. This separation helps focus observation or testing on the islets rather than on surrounding material. The resulting preparation is suited to controlled assessment of morphology, viability, and insulin secretion.
A basic workflow begins with introducing a pancreatic islet suspension into the microplate so the islets can become positioned within the defined microwell array. Excess medium and smaller debris are then removed while the retained islets remain in place. The localized samples can subsequently be observed, cultured, or tested in the same controlled format.
Captured islets can be evaluated for viability, morphology, and glucose-stimulated insulin secretion. Their localized arrangement supports observation of individual islets and controlled testing within the plate. Together, these measurements provide information about islet condition and pancreatic function, making the format useful when researchers need to compare samples or experimental conditions.
In biology research, these microplates support workflows that examine pancreatic function, screen compounds affecting insulin release, and evaluate conditions relevant to diabetes and islet transplantation. Their value comes from combining localized islet handling with measurable functional outcomes. Researchers can therefore study treatment effects or experimental conditions using viability, morphology, and secretion-related assessments.
