FAQs
1
How to ensure the sgRNA coverage during library plasmid amplification?
To ensure appropriate coverage of sgRNA during library plasmid amplification, high-efficiency electrocompetent cells should be used for plasmid transformation via electroporation. Additionally, the number of colonies should exceed 300 times the number of sgRNAs (number of colonies > sgRNA count * 300) to effectively ensure that the coverage of the amplified plasmid sgRNAs is not affected.
2
How to change the antibiotic resistance of library plasmids?
Unlike conventional plasmid antibiotic resistance modification, library plasmid modification cannot be done directly using the library plasmid, as this would result in significant loss of sgRNA sequences. To change the antibiotic resistance of the library plasmid, the backbone of the library plasmid must be modified first, and then the sgRNA sequences are integrated into the modified backbone through homologous recombination.
3
How to detect the coverage and uniformity of sgRNA in library plasmids?
The coverage and uniformity of sgRNA in library plasmids need to be assessed by NGS sequencing. Specifically, primers should be designed at both ends of the sgRNA sequences, and high-fidelity enzymes should be used to amplify the library plasmids; the resulting amplification products are then subjected to NGS sequencing and analysis.
4
What is the fragment size for PCR amplification of library plasmids?
Currently, the sequencing method mainly uses PE150, which refers to paired-end sequencing of 150 bp read length, resulting in a total read length of 300 bp. To ensure that sgRNA information can be identified, it is advisable not to exceed a PCR amplification fragment size of 300 bp.
5
Can library plasmids be directly used to construct library cells?
Library plasmids cannot be directly used to construct library cells. When library plasmids are transfected into cells via transient transfection, the sgRNA sequences cannot integrate into the genome; despite various gene editing occurring in the cells, the remaining sgRNA sequences within the cells cannot be detected through NGS sequencing.

Cas9 Stable Cell Line
The Cas9 cell lines in our cell bank can stably express Cas9 protein. So gene knockout can be achieved by transfecting gRNA. Simultaneously transfecting gRNA and donor DNA can achieve gene knock-in/point mutation, effectively improving experimental efficiency.
