Product overview


UnlCas12f1 (previously known as Un1Cas14a) is an endonuclease that specifically binds and cleaves ssDNA target under the guidance of tracrRNA and crRNA (or sgRNA alone), and does not require a PAM site. In addition, Un1Cas12f1 can also specifically cleave dsDNA target in a PAM-dependent manner, causing DSBs and generating sticky ends. Similar to other Cas12 family proteins, Un1Cas12f1 protein also has the trans-cleavage activity against ssDNA, and both dsDNA or ssDNA targets can trigger its trans-cleavage activity, that is, when Un1Cas12f1 binds sgRNA and target DNA to form a ternary complex, it releases trans-cleavage activity to non-specifically cleave ssDNA sequences in the reaction system.

Compared with other Cas proteins, Cas12f1 protein is generally smaller (400-700 AA). Similar to Cas12a and Cas12b, Cas12f can also be used to develop CRISPR-Dx systems for rapid detection of nucleic acids (For details, please refer to PMID: 30337455).
