I performed high pressure freezing for TEM of C. elegans eggshells. HPF is the only fixation available to study EM of C. elegans and results are often more variable. My poster will describe the procedure using the Leica EM HPM100 and the tissue embedding process. The main issue faced during the preparation was extracting fully intact worms from the HPF sample carriers. I conclude with a solution to a more effective approach when embedding samples.
