Does anyone have a in-house immunostaining protocol to stain for organoids? I am guessing my antibody is not able to permeate well. If anyone has any in house protocol that works best to stain organoids, please do share!
We currently use this buffer for all blocking, washing and incubation steps: (1x PBS + 1% Triton-X +2% DMSO). In the end, you have to optimize conditions for your specific application.
