RNA isolation / purification Tissue - Human ileum

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
- The MagNA Pure LC 2.0 Instrument, together with its software is required for analysing the yields of this kit.

- Do not use more sample than this kit is designed to handle.

- Do not allow Wash Buffer I or the Lysis/Binding Buffer to mix with sodium hypochlorite (bleach) solution. This mixture can produce a highly toxic gas.
Protocol tips
- To yield high RNA, give the column an extra wash with both RW1 and RPE buffers (3 total washes with each buffer).
Downstream tips
- Include DNAse treatment for 15-20min.

- Ensure EtOH is completely evaporated off of the column prior to elution. Adjust time from 1min to 5 min at 60`C.

- Use water to elute the RNA that is warmed to ~60`C.
Upstream tips
- This kit can be used for the isolation of RNA from ≤ 5 mg animal tissue.
Protocol tips
- To avoid DNA contamination, either reduce sample size, or include an additional DNase treatment step after RNA isolation
Downstream tips
- If there is low yield and/or inconsistent yield, lowering the amount of sample input may improve results
