Comparison of the RNA Quality of Native Tissue Samples with Tissue Samples after UV Laser Microdissection

To compare untreated tissue samples with fixed and stained tissue samples, three cryo-asserved murine brains of known RNA integrity (RIN) were used. After cryo-asservation at –80 °C, these were transferred to a cryomicrotome and incubated at –35 °C for 45 min. Then the tissue was equilibrated at –18 °C for 30 min and cut into 12 µm sections at –18 °C by …

Even Insect Fragments Throw Light on How Crimes Are Committed: How Forensic Biologist Dr. Mark Benecke Gains Insights

Mark Benecke does have one thing in common with the TV detectives, though: In emergencies he can be contacted around the clock. Occasionally, a crime novelist will call him on his emergency number to ask if it’s possible to dissolve corpses in hydrochloric acid. “That’s not an emergency, of course,” says the forensic biologist. “Due …
