Description

Cas12a (Cpf1) is a novel CRISPR-Cas DNA nuclease, providing a significant complement to the Cas9 system with the following advantages:

• Expanded Editing Sites: Cas12a recognizes T-rich PAM sequences, enabling genome editing in AT-rich genomes (e.g., zebrafish).

• Enhanced Editing Efficiency: Cas12a creates staggered sticky ends at the 5' end of the sequence, improving homologous recombination repair (HDR) efficiency and thus increasing gene editing efficiency.

• Shorter gRNA: Cas12a's crRNA is around 40-44 nucleotides (including a 20-nucleotide constant region and a 20-24 nucleotide specific binding region), making chemical synthesis simpler and more cost-effective.

Leveraging over 20 years of oligonucleotide synthesis experience, SBS Genetech offers customized Cas12a crRNA synthesis services, supporting AsCas12a/LbCas12a and various other customized Cas12a crRNA syntheses. With high purity, precise molecular weight, and verified high gene knockout/knock-in efficiency, it is an ideal choice for conducting Cas12a-related gene editing experiments.
