200 PLG X TRIZOL LS 200ML EA，A33253，赛默飞世尔

This system includes both TRIzol™ LS Reagent and Invitrogen™ Phasemaker™ Tubes.

TRIzol LS Reagent is a complete, ready-to-use reagent for the isolation of high-quality total RNA from a variety of liquid biological samples such as serum and virus preparations.

Phasemaker Tubes contain a thick liquid polymer that separates and completely isolates the upper aqueous phase of the TRIzol Reagent mix from the organic phase underneath, greatly simplifying removal of the upper phase containing the RNA. This TRIzol LS Reagent and Phasemaker Tubes Complete System is for the extraction of RNA, not DNA or protein. It will accommodate approximately 0.25 mL of sample.
