J23119-CXCL9
The short version of DNA sequence coding for CXCL9 mRNA can be expressed under the control of a strong promoter J23119.
Usage and Biology
1.This plamsid can transfer CXCL9 mRNA. CXCL9 mRNA is a biomarker, based on the final intensity of the fluorescence, we can know if a person is sick.
2.It can be used in other experiments for disease markers.

It can transfer CXCL9 mRNA to combine with the complex of igRNA and Cas9 protein. Then they can perform cutting function. And they can cut tetR of P70-σ28-P28-tetR to express fluorescence of P28-tetO-deGFP.We know from experiments that the dCas9-igRNA complex which combined with CXCL9 has higher fluorescence intensity.
Design Page
CXCL9 mRNA, a biomarker indicative of rejection in renal-transplant recipients. We found that existing techniques for detecting rejection in kidney transplantation can not be used to detect disease in a non-invasive manner. And CRISPR-Cas has the potential to detect disease.So we use CRISPR-Cas9 to verify if this system can detect CXCL9 mRNA or other biomarkers.
