CRISPR 101: Ribonucleoprotein (RNP) Delivery - Addgene
Cas9 RNPs are detectable at high levels shortly after transfection, and are quickly cleared from the cell via protein degradation pathways. This makes Cas9 RNPs useful for CRISPR applications where limited expression of Cas9 is required and specificity is a concern, such as knockout generation or homologous recombination.
Strategies in the delivery of Cas9 ribonucleoprotein for CRISPR/Cas9 ...
Jan 1, 2021 · In this review, we summarized the current Cas9 RNP delivery systems including physical approaches and synthetic carriers. The mechanisms and beneficial roles of these strategies in intracellular Cas9 RNP delivery were reviewed. Examples in the development of stimuli-responsive and targeted carriers for RNP delivery are highlighted.
Strategies in the delivery of Cas9 ribonucleoprotein for CRISPR/Cas9 …
Cas9 RNP complexes targeting p38 mitogen-activated protein kinases (MAPKs) were efficiently delivered into human MDA-MB-231 and SUM-159 breast cancer cells and primary human CD4 + T cells, resulting in indels frequencies of 43%, 47% and 33%, respectively. Cas9 RNP delivery induced lower off-target mutations frequency (0.8%) than plasmid ...
