RNA isolation / purification Tissue - Human Teeth / Jaw

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	Protocol tips	Downstream tips
- This kit purifies RNA from up to 30 mg tissue		- If there is low RNA yield,Repeat RNA elution, incubate the RNeasy Mini spin column on the benchtop for 10 min with RNase-free water before centrifuging. - If there is low Low A260/A280 value use 10 mM Tris·Cl, pH 7.5, not RNase-free water, to dilute the sample before measuring purity. - If RNA does not perform well in downstream experiments this could be due to salt carryover dyuring elution step, so ensure that Buffer RPE is at 15–25°C.
