The best way to isolate miRNA is using kits. I recommend mirVana miRNA Isolation Kit from Thermo Fisher.

Venkatesh Vaidyanathan

Hello Joshua,

Yes, miRNA from tissues in experimental animals can be isolated.

The miRNA signatures may not be the same as the ones expected obtained from human diseases.

And yes, mirVana is the best kit, if I were to be asked as well.

Warm regards,

Venk

Zaynab Saad

hii >> ive used this kit InvetrogenTM / life technologies/ USA for microRNA extraction from tissue samples... with high purity and good concentration

good luck

Radha Pallati

Hi,

We played around with quite a few commercial miRNA extraction kits, and felt mirVana was by far the best, in terms of yield of miRNA.

Regards,

Radha
