Need to put tissue in RNAlater RNA stabilization reagent or store at -70 C

-q
 After disruption and homogenization in Buffer RLT (lysis buffer),
samples can be stored at –70°C for months.

need to disrupt tissue in tissuelyser or tissueRuptor or mortar and pestle

disruption and homogenization are two different things

-q
Cell and tissue lysates can be homogenized using a syringe and needle. Lysate is
passed through a 20-gauge (0.9 mm) needle attached to a sterile plastic syringe at least
5–10 times or until a homogeneous lysate is achieved. Increasing the volume of lysis
buffer may be required to facilitate handling and minimize loss.

homogenization using QIAshredder homogenizer option

Generally, DNase digestion is not required with RNeasy Kits since RNeasy silica-
membrane technology efficiently removes most of the DNA without DNase treatment.

-q
optional on-
column DNase digestion using the RNase-Free DNase Set
