dCas9-delta alpha

dCas9 fused with Δα segment of β-glactosidase

For their ease of use, low assay time, cost-effectiveness, high sensitivity, electrochemical biosensors have emerged as an attractive method for molecular detection. Combing with our PC Reporter we may further enhance it's applicability, that is to implement pathogen diagnostics in settings outside clinics and without the need of specialized analytical laboratories.

β-glactosidase (LacZ) is an exoglycosidase from E.coli, composing of 1024 amino acids. LacZ is a commonly used as a reporter, known for blue white screen, which catalyzes X-gal to produce blue dye; by using different substrates, for example ONPG, reaction can be measured quantitatively.

In our project, we could dissect LacZ as Δα, ∆ω segments to fuse with dCas9 to do the same as our PC Reporter.
