( RNAlater TissueProtect Tubes provide R...)Critical factors for successful microarray and real-time PCR analyses

RNAlater TissueProtect Tubes provide RNAlater Reagent in easy-to-handle, reclosable tubes for immediate RNA stabilization at sample collection. This is especially important in fields such as molecular diagnostics, in order to immediately stabilize biopsies and other tissue samples directly after excision in a clinical environment, where liquid nitrogen is not allowed. Stabilized samples can be transported and easily processed at room temperature. QIAGEN provides a range of RNA stabilization reagents, including RNAprotect Bacteria Reagent for Grampositive and Gram-negative bacteria.

Integrated RNA stabilization and purification

The PAXgene Blood RNA System from PreAnalytiX provides a standardized system for integrated collection of blood samples with stabilization and purification of their RNA. RNeasy Protect Kits for animal tissues and RNeasy Protect Bacteria Kits integrate RNA stabilization and purification in a single kit. RNeasy silica-gelmembrane technology can also be fully automated with reaction setup on the BioRobot 8000, an ideal front-end tool for subsequent array or quantitative RT-PCR analyses.

Efficient cDNA labeling and cleanup for more true positive spots on microarrays

A common bottleneck to sensitive and reproducible array analysis is poor cDNA labeling efficiency and suboptimal cDNA cleanup. The new LabelStar Array Kit is specifically developed for microarray cDNA labeling, and provides a novel denaturation solution that resolves secondary
