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?

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?
Found 3 matching solutions for this experiment
|- For RNA to dissolve better and to yeild high levels, preheat elution buffer at 95C.
- Addition of β-mercaptoethanol in lysis buffer can be skipped because the phenol will do the job of nuclease inactivation
- To capture more amount of mRNA, modify the amount of lysis buffer :ethanol (from 1:1 to 1:1.5) during the binding step
|- Do vortex for 2-plus minutes during Acid-Phenol:Chloroform extraction step. This will facilitate the removal of tightly bound proteins typically associated with RNA
|- To yield high RNA, give the column an extra wash with both RW1 and RPE buffers (3 total washes with each buffer).|
|- 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.
