I want to extract RNA from my 3D spheroids. Can I store the spheroids in lysis buffer at -80 for a week and then extract RNA. I use the Bioline RNA Micro kit.
You can store spheroids in lysis buffer at -80 for long term. Just ensure that the spheroids are lysed properly before storing them. If not lysing properly, then you can use micropestle to crush the spheroids and store them. By this method, you'll get a good yield of RNA.
