CRISPR-Cella Plasmid

CRISPR-Cas9 is short for clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9. The CRISPR-Cas9 system has generated a lot of excitement in the scientific community because it is faster, cheaper, more accurate, and more efficient than other genome editing methods. When compared with the ZFN and TALEN technologies, the CRISPR/Cas9 technique has higher efficiency to generate nucleotide(s) insertion or deletion via non-homologous end joining (NHEJ) and homologous recombination (HR), which conveniently allows for new discovery of gene functions and molecular mechanisms of human genetic diseases. We produce plasmid DNA for a wide variety of R&D, clinical, and commercial bioprocessing applications, including knockout Plasmid and knocking plasmid.

Knockout Plasmid

Classification of knockout gRNA plasmids are Lentiviral plasmid, Adenovirus-associated virus plasmid and non-viral plasmid with EFP and mCherry reporter genes. These plasmids are carrying the selection marker and will be selected with the Puromycin, Neomycin and other similar antibiotics.

Knock-in Plasmid

In addition to creating indels or knockouts, scientists can encourage a precise form of repair (homology-directed repair; HDR) by providing a DNA sequence that the cell can use as a repair template to insert (knock in) a matching DNA sequence into the break. Example applications include modification of a promoter sequence or gene, insertion of an exogenous reporter (e.g., a fluorescent protein), or creation of a clinically relevant SNP for a disease model. It should be noted that knocking efficiency is usually lower than knockout efficiency. Moreover, knocking at one copy of the gene/sequence is usually accompanied by a knockout/indel at the second copy; both copies are cut by the Cas9/sgRNA complex but one is likely repaired imprecisely using the non-homologous end joining (NHEJ) pathway, creating an indel.
