I'm working on a project that involves the extraction of RNA for nasal epithelial tissue and I am trying to improve my RNA yields. I have been using motorized pellet pestle to disrupt the tissue prior to extraction with RNeasy mini kit but it looks like we need a more aggressive method. I'm currently looking at the Qiagen TissueRuptor and Omni TH Tissue Homogenizer. If anyone has any suggestions on good tissue homogenizers under $1000 as well as other extraction strategies they would be greatly appreciated.
