This video describes freeze-cracking, a method to make C. elegans tissues accessible for antibody staining by disrupting the cuticle.
Protocol
This protocol is an excerpt from Zhang et al, The C. elegans Intestine As a Model for Intercellular Lumen Morphogenesis and In Vivo Polarized Membrane Biogenesis at the Single-cell Level: Labeling by Antibody Staining, RNAi Loss-of-function Analysis and Imaging, J. Vis. Exp. (2017). Antibody staining of the C. elegans intestine Fixation Take a clean glass slide and use poly-L-lysine to genera…
