Do you have a protocol for the preparation of tissues preserved in RNAprotect Tissue Reagent for pathological studies?

RNAprotect Reagents and Tubes provide immediate RNase inactivation and stabilization of RNA in tissues, cultures of Gram-positive and Gram-negative bacteria and sorted or cultured cells to preserve the gene expression profile and enable reproducible purification of high-quality RNA. Samples are stabilized at room temperature prior to RNA isolation procedures.
