Guest lecture recorded July 28, 2020 with Professor Richard Sherwood, Assistant Professor of Medicine at Brigham and Women’s Hospital. Molecular cloning is essential to research in genetics and cell biology. In this webinar, Dr. Sherwood shares how his lab uses molecular cloning to power their work in genetics and CRISPR/Cas9 genome editing.

This video shows how the Cas9-gRNA complex cleaves DNA visualized in real-time using atomic force microscopy. Astonishingly, single molecules of Cas9 and DNA can be made visible with this technology.

This video illustrates how to test guide RNAs to facilitate the cleaving of a macrophage gene in vitro.

Guest lecture recorded July 30, 2020 by Dr. Jessica Whited, Assistant Professor of Stem Cell and Regenerative Biology at Harvard University. Dr. Whited studies limb regeneration in axolotl salamanders, with the ultimate goal of discovering how to regenerate limbs in patients. In this webinar, Dr. Whited discusses how her work involves using Cas9-mediated gene drives to generate axolotls with the desired genetic backgrounds.
