Comprehensive molecular profiling of human tumor tissue specimens at the DNA, mRNA and protein level is often obstructed by a limited amount of available material. Homogenization of frozen tissue samples in guanidine isothiocyanate followed by ultracentrifugation over cesium chloride allows the simultaneous extraction of high-molecular weight DNA and RNA. Here, we present a protocol for ...
