All our TRIzol-based RNA prep kits, including the Phasemaker Tubes (Cat. No. A33248) include a chloroform-based phase separation step that cannot be skipped.
The polymer in Phasemaker Tubes is inert and heat-stable, and does not affect standard downstream applications performed after RNA extraction.
Yes you can. As RNAlater incorporates salts into the sample, the salt content can increase the density of the sample mix, so we recommend adding RNAse-free water (50-100 µL) to the sample mix.
Phasemaker Tubes work on the principle of density gradient centrifugation. Phasemaker Tubes contain a thick liquid polymer that is heavier than the aqueous phase of the TRIzol Reagent mix, but lighter than the organic phase, so after centrifugation, the polymer positions itself between these two layers and forms an exclusive physical barrier. It separates and completely isolates the upper aqueous phase from the organic phase underneath, making it very easy to aspirate the upper phase containing the RNA.
Phasemaker Tubes work exclusively with TRIzol Reagent (and TRIzol LS Reagent ). As other similar reagents may have different density, Phasemaker Tubes may not work properly.
