Abstract
Isolation of intestinal organoids from matrigel or cultrex growth domes ready for protein or RNA isolation.
Protocol materials
Cultrex® 3-D Culture Matrix™ Reduced Growth Factor Basement Membrane Extract, PathClear®Merck MilliporeSigma (Sigma-Aldrich)Catalog #3445-001-01
Phosphate Buffered SalineThermo Fisher ScientificCatalog #28374

Intestinal organoids are grown in 30 µL Cultrex® 3-D Culture Matrix™ Reduced Growth Factor Basement Membrane Extract, PathClear®Merck MilliporeSigma (Sigma-Aldrich)Catalog #3445-001-01 domes for 240:00:00
1w 3d
Once organoids are large enough for harvest domes are washed three times with ice cold Phosphate Buffered SalineThermo Fisher ScientificCatalog #28374 .
AddCell Recovery solutionCorningCatalog #354253 1 mL per well. incubate on ice for 01:00:00 with orbital shaking at 100 rpm, 4°C .
1h
Harvest well contents into centrifuge tube. Centrifuge 6000 rpm, 00:01:00 . Carefully remove supernatant and add 1 mL of 4 °C PBS. Incubate on ice for 00:05:00 .
6m
Centrifuge 6000 rpm, 4°C, 00:01:00 . Carefully remove the supernatant and as much solidified matrigel as possible leaving behind organoids. Cell pellet is ready for RNA or protein extraction.
