Get a high level overview of CRISPR/Cas9 and how it is used in genome editing in our Science in 60 segment.
CRISPR systems evolved as a means of bacterial adaptive immunity. Understanding their behavior in vivo is essential to harnessing their power in vitro.
In this webinar you will learn how to increase editing efficiency by directly introducing Cas9 ribonucleoproteins (RNPs) to cells through electroporation or lipofection. Rapid sgRNA synthesis requiring only a single user-supplied ~55mer single-stranded DNA oligonucleotide is described. Methods for assessing genome editing efficiency will be discussed including T7-endonuclease I-based methods, sequencing-based methods, and in vitro Cas9 digestion.
