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.
