Flash Freezing and Cryosectioning E12.5 Mouse Brain

<p class="jove_content">Demonstrated in this video are the techniques for flash freezing and sectioning embryonic brain tissue from mouse.  Useful tips for using the cryostat are given, including troubleshooting methods that can be used while cutting to ensure that the resultant tissues sections are free of cracks and other distortions.</p>
