Description

Description: HighYield T7 AF405 RNA Labeling Kit is designed to produce randomly AF405-modified RNA probes via in vitro transcription. Such probes are ideally suited for in situ hybridization and Northern Blot experiments. AF405 (also known as Alexa Fluor® 405) is a hydrophilic dye with excellent photostability. UTP-PEG5-AF405 is efficiently incorporated into RNA as substitute for its natural counterpart UTP using an optimized reaction buffer and T7 RNA Labeling Polymerase Mix. 35 % UTP-PEG5-AF405 substitution typically results in an optimal balance between reaction and labeling efficiency. Individual optimization of UTP-PEG5-AF405/UTP ratio however, can easily be achieved with the single nucleotide format. The resulting AF405-modified RNA probe can subsequently be detected by fluorescence spectroscopy. The kit contains sufficient reagents for 20 labeling reactions of 20 µl each (35 % UTP-PEG5-AF405 substitution, 2.5 mM ATP, GTP, CTP, 0.2 mM UTP, 0.1 mM UTP-PEG5-AF405). A 20 µl reaction yields about 5-7 µg RNA after 30 min incubation (1 µg T7 control template, 1.4 kb RNA transcript). Yields may however vary depending on the template (promotor design, sequence length, secondary structure formation).
