TIVA

Transcriptome in Vivo Analysis

TIVA is a protocol that captures mRNA from live cells (Lovatt et al., 2014). In this method, a photoactivatable TIVA tag is loaded into cells. Selective photoactivation exposes the mRNA-capturing portion of the tag, allowing it to hybridize to the poly(A) tails of mRNA. The biotin-bound mRNA is captured using streptavidin-coated magnetic beads and transcribed into cDNA. Sequencing the cDNA provides transcriptome analysis of RNA from single cells in complex tissues.

Advantages:

  • in vivo transcriptome analysis using photoactivation in neuronal cells
  • Noninvasive method for capturing mRNAs in their natural microenvironment

Disadvantages:

  • Limited to a small number of cells


Reagents:

Illumina Library prep and Array Kit Selector
