Chitra Magna, an innovative RNA extraction kit, has been developed by Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST) 

  • The protocol for the kit uses magnetic nanoparticles to capture and concentrate the RNA from the patient sample.  
  • The magnetic nanoparticle beads bind to the viral RNA and, when exposed to a magnetic field, give a highly purified and concentrated level of RNA.  
  • As the yield of PCR or LAMP test is dependent on getting an adequate quantity of viral RNA, this innovation enhances the chances of identifying positive cases. 
  • Chitra Magna can be used to extract high purity RNA from patient samples not only for LAMP testing but also for the RT-PCR test. 

Significance : This is of significant advantage because even if some viral RNA disintegrates during storage and transportation of the patient samples, all of it is captured by the magnetic bead-based extraction technology.
