Custom Stellaris® FISH Probes
Product Description
Spheroplasting buffer (10 mL Buffer B + 100 µL of 200 mM vanadyl ribonucleoside complex) A set of Stellaris FISH Probes comprises up to 48 single-labeled oligonucleotides designed to selectively bind to targeted transcripts. Stellaris FISH Probes bound to target RNA produce fluorescent signals to permit detection of single RNA molecules as diffraction-limited spots by conventional WARNING! Formamide is a teratogen that is easily
absorbed through the skin and should be used in a
Storage Guidelines
Stellaris FISH Probes are shipped dry and can be stored frozen WARNING! Be sure to let the formamide warm to room
temperature before opening the bottle.
Final composition is 100 mg/mL dextran sulfate and Short-Term Storage & Daily Use Dissolved probe mix should be subjected to a minimum number of freeze-thaw cycles. For daily and short-term use, the mix can be stored at +2 to +8 °C in the dark for 1 mL 20X saline-sodium citrate (SSC), nuclease-free We recommend freezing probes in the dark at -15 to Nuclease-free water to 10 mL final volume -30 °C for storage lasting longer than a month.

Standard fluorescence microscope (e.g., Nikon TE2000 probes labeled with Quasar 570 and Quasar 670 dyes, and is incompatible with fluorescein dye. For probes Strong light source, such as a mercury or metal-halide labeled with fluorescein, instead use commercially lamp (xenon or LED are typically not bright enough).

• ED is a symptom of many underlying conditions • Endothelial dysfunction seems to be a common final pathway to ED in patients with hyperlipidemia, diabetes mellitus, hypertension, and chronic renal failure• The recognition of ED as a warning sign of silent vascular disease has led to the concept that a man with ED and no cardiac symptoms is a cardiac patient until proven otherwise
