Usage and Biology

This biological part is specially designed to target a RED plasma. The principle behind this is that CRISPR-Cas12a (Cpf1) proteins are RNA-guided enzymes that bind and cut DNA as components of bacterial adaptive immune systems like CRISPR-Cas9. We designed the crRNA which is able to combine with the Cas12a protein and recognize the target DNA. According to this principle, we designed a crRNA that matched with one fragment of RED plasma., which brings Cas12a to its target, specifically cleaves the RED plasma. Through this method, we are theoretically capable of targeting any single base mutation on ctDNA which are dispersed in people’s blood.
