Interview mit Herrn PD Dr. Hadji für Brustkrebs Deutschland e.V. Osteoporose und erhöhtes Osteoporoserisiko nach adjuvanter Therapie bei Brustkrebs Brustkrebs ist in die Deutschland die häufigste Krebserkrankung bei Frauen. Jedes Jahr erkranken ca. 50 000 Frauen neu an Brustkrebs. Die Erkrankung und vor allem ihre Behandlung können sich stark auf die Knochendichte auswirken. Renate

Preserve RNA Integrity during Immunofluorescence Processing
Simplify Fluorescent Target
Identify target cells for Laser CaptureMicrodissection (LCM) and gene expressionanalysis using antigen markers to highlightspecific surface or intracellular proteins. TheHistoGene LCM ImmunofluorescenceStaining Kit is the only Kit specifically designedfor retrieval of high-quality RNA fromimmunofluorescently stained frozen tissuesections. The Staining Kit provides reagents andslides for convenient and reliable immuno-fluorescent staining. The Kit provides aprotocol streamlined and optimized to maintainRNA quality and materials sufficient forprocessing 32 slides.
