WebJan 8, 2024 · In stark contrast, by using shRNA over CRISPR/cas9 combined methodology, we clearly demonstrate that the Sema4B targeted shRNA effects on cell proliferation is the result of off-target effects. Nevertheless, it also revealed that certain splice variants of Sema4B are important for the ability of glioma cells to grow as individual clones. WebThe CRISPR-associated protein is a non-specific endonuclease. It is directed to the specific DNA locus by a gRNA, where it makes a double-strand break. There are several versions of Cas nucleases isolated from different bacteria. The most commonly used one is the Cas9 nuclease from Streptococcus pyogenes. Figure 1.
