Do you have any data showing differences in RNA extraction with TRIzol Reagent, the PureLink RNA Mini Kit, ChargeSwitch Total RNA Cell Kit or the TRIzol Plus RNA Purification Kit?

What is the difference between the TRIzol Plus RNA Purification Kit and TRIzol Reagent?
The TRIzol Plus RNA Purification Kit combines the lysis capability of TRIzol Reagent with the convenient RNA extraction technology of the silica spin columns included in the PureLink RNA Mini Kit.

What chloroform do you recommend I use for RNA extraction with TRIzol Reagent? Are there any substitutes I can use?
We recommend using straight chloroform. No isoamyl alcohol is needed (though using chloroform:isoamyl alcohol 49:1 works without problems). You can also use chloroform with 50 ppm amylene. Alternatively, BCP (1-bromo-2 chloropropane) can be used in the place of chloroform.

What is the smallest sample volume I can use when extracting RNA with TRIzol Reagent?
Small volumes (0.5-0.8 mL) of TRIzol Reagent have been used successfully for 10^2 to 10^5 cells, but if small volumes are used, we recommend using smaller tubes in order to have the tallest possible column of aqueous phase. The taller the column of liquid, the less likely that contamination from the interphase will occur.
Here is a protocol for isolation of RNA from small quantities of tissue (1-10 mg) or cells (100-10,000):
1. Add 800 µL TRIzol Reagent to the sample. Homogenize cells by pipetting repeatedly. Add 200 µg glycogen (Cat. No. 10814010) directly to the TRIzol Reagent. If processing tissue, pulverize in liquid nitrogen first and then add 800 µL TRIzol Reagent containing 200 µg glycogen (final concentration 250 µg/mL) followed by vigorous vortexing or power homogenization.
2. Place at room temperature, cap the vial, and vortex at high speed for 10 seconds. Make sure the TRIzol Reagent wets the side of the vial in order to solubilize any sample that may be remaining on the walls.
3. Shear the genomic DNA in the sample by passing twice through a 26-gauge needle connected to a 1 mL syringe. Using the syringe, transfer the sample to a sterile 1.5 mL microcentrifuge tube.
4. Add 160 µL of chloroform (or 49:1 chloroform:isoamyl alcohol) to each sample and vortex up to 30 seconds. Centrifuge at maximum speed in a microcentrifuge for 5 minutes to separate the phases.
5. Transfer the upper aqueous phase to a fresh tube and add 400 µL ice-cold isopropanol. Allow the samples to precipitate at -20 degrees C for 1 hour to overnight. Pellet the RNA by centrifugation at maximum speed in the microfuge for 15 minutes at room temperature.
6. Decant the supernatant. Wash the pellet in 200 µL of 70% ethanol and centrifuge again for 10 minutes at maximum speed. Decant the supernatant, removing as much as possible without disturbing the pellet. Dry the RNA pellet.
7. Resolubilize the pellet in 30-50 µL RNAse-free deionized water. If tissue is high in RNAses (e.g., adrenal gland, pancreas), resuspend in 100% deionized formamide. Be sure to vortex or pipette the sample up and down to ensure that the pellet is fully resolubilized. Store at -70 degrees C.
