Procedure 1. A pair of fine forceps with a region of ~1 mm in width is used to hold the thin end of an autoclaved gel-loading tip in a perpendicular position (Figure 1).

Protocol overview
• This protocol covers tissue sectioning and macrodissection steps in preparation for RNA extraction from FFPE tissues. Although originally developed for RNA extraction using the Optimum FFPE RNA Isolation Kit (Ambion, UK), the protocol is relevant for FFPE tissue preparation for RNA extraction using any extraction method
• Macrodissection is carried out at 2× magnification using a dissecting microscope with external fiber-optic illumination
• Adopt strict RNase-free handling conditions throughout, including the use and frequent changing of powder-free latex gloves.

Protocol overview
• The extraction method (steps 2–21) is taken from the method supplied with TRIzol reagent (Invitrogen, Paisley, UK).
• Recover tumor tissue at the time of surgery, trim into 1-cm3 fragments, and immerse immediately in TRIzol reagent prior to freezing at -80°C.

Instructions for use
For the production of zygotes and pseudopregnant females to serve as recipients, standard transgenic methodologies are used. Matings are set up with male and female mice as in standard transgenic procedures.
