  • Webinars, tips, and best practices, product selection guides, product samples, and other support tools designed to keep you informed, simplify the decision process, and help ensure optimal performance.

RNA extraction

RNase-free workspace
RNase-free lab essentials
RNA extraction
RNA stabilization

Choose from several proven options to eliminate RNase contaminants on lab surfaces.

Avoid, detect, and inhibit contaminating RNases with RNase-free buffers, reagents, water, and plastics.

Extract RNA from samples and crude lysates with silica spin columns or magnetic beads. Our automated Kingfisher instruments offer additional speed, consistency, and reproducibility during this important first step.

Stabilize and preserve the integrity of your RNA, either at the point of collection or post-collection

RNA quantification


Fluorogenic dyes selectively bind to DNA or RNA and only emit a signal when bound to the target molecule. This method is recommended when measuring dilute samples.

Spectrophotometry utilizes UV-Vis absorbance at 260 nm to quantify the amount of nucleic acid in a sample, and can measure purity with absorbance ratios.

Reverse transcription



Thermo Fisher Scientific offers a wide variety of pre-designed and custom primers and probes, available with more than 50 modification including MGB, TAMRA, and QSY.
