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 4 matching solutions for this experiment
|- 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.
|- Isolation of RNA from a small amount of tissue (1-10 mg) can be accomplished by homogenizing the sample in 0.8 ml of RNA-Bee.
- Adjust buffers to pH to 6.5 - 7.5 if they have have an acidic pH for better results.
|- An additional wash with 75% ethanol improves 260/280 ratio
