RNA isolation / purification Tissue - Rat Lymph node

Isolating RNA from tissues and paraffin-embedded tissue samples can be challenging due to cross-linking of biomolecules and fragmented nucleic acids. The best solution is to slice the tissues into smaller pieces and make a homogenate solution (using tissue homogenizer or grinding liquid nitrogen frozen samples) in presence of RNAse inhibitors. The homogenization process should be carried out on dry ice to maintain the integrity of RNA

RNA isolation from tissue

How do I extract RNA from animal tissue without using liquid nitrogen? I tried the RNA extraction by using the TRIzol reagent and I homogenize the tissue using polytron homogenizer at room temperature for 30secs is this correct?

Problem in phase separation after using serum/plasma kit

I used a serum/plasma kit for my serum samples. After the phase separation the samples should have 3 phases: a colourless aqueous phase, a white interphase and a red organic phase. However, in some of my samples there was no aqueous phase unless I wait for an extended period of time. How can I circumvent this problem?

Upstream tips
- Aliquot rDNase and store at -20 °C.
Protocol tips
- Dry the columns very well after the ethanol wash by adding an additional 2' >10000 rpm centrifuge with no buffer.
