I work with Human liver organoids and I would like to know the impact of FBS on the organoids. Since the composition of FBS is unknown, would you recommend any alternatives such as human platelet lysate?

I have tried to fabricate Liver organoids and would like to study the impact of FBS on healthy and tumor organoids. Since the compositions of FBS is unknown, do you recommend any alternatives like Human platelet lysate, etc?

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?

The biggest problem in isolating RNA from gram-positive bacteria is the disruption of the cell wall. A lot of protocols employ enzymatic digestion (pretreatment) which may affect gene expression patterns of certain genes. Therefore physical disruption using beads could be the best alternative.

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?

Generally it has been difficult to isolate high-quality RNA from yeast because of problems disrupting the cells. Use of enzymes to disrupt cell wall can alter gene expression profiles. Therefore, physical disruption can result in high quality RNA for all downstream processing. Use of DNAse and proteinase K will remove traces of DNA contamination and proteins respectively.
