This video demonstrates the isolation of capillaries from fresh porcine brains. The process involves removing the meninges, isolating the grey matter from the brain tissue, homogenizing and filtering the grey matter to isolate the capillaries, and finally using enzymatic digestion to purify the capillaries further.
Protocol
All procedures involving sample collection have been performed in accordance with the institute's IRB guidelines. 1. Purification of Porcine Brain Capillaries Collect 8-10 brains from 5-6-month-old domestic pigs (e.g. from a nearby slaughterhouse) and transport them on ice to the laboratory. We recommend starting the following purification procedure within 2-3 h of termination of the animal. Place the brains in a sterile flow bench and gently…
