Stellaris® FISH Probes, Nematode Dauer larva development regulatory growth factor daf-7 with CAL Fluor® Red 610 5 nmol Total +2 to +8 °C

Stellaris FISH (fluorescence in situ hybridization) is a RNA visualization method that allows simultaneous detection, localization, and quantification of individual RNA molecules at the sub-cellular level in fixed samples using widefield fluorescence microscopy. A set of Stellaris FISH Probes comprises multiple oligonucleotides with different sequences each with a fluorescent label that collectively bind along the same target transcript to produce a punctate signal.

The Stellaris FISH technology follows a simple protocol, does not use exotic reagents, is inexpensive and platform-independent, offers same-day results, and is versatile toward many sample types and applications. Scientists may even label Stellaris FISH probes with a number of various dyes to allow for multiplex detection of different RNA targets simultaneously. Finally, scientists can address the stochastic nature of gene expression and visualize RNA through direct detection without isolation, purification, and amplification.
