Aminoallyl-UTP-PEG5-AF647

Product Introduction

Aminoallyl-UTP-PEG5-AF647 is a conjugated nucleoside triphosphate featuring a PEG5 spacer linked to the Alexa Fluor 647 dye, a member of the sulfonated cyanine dye family known for its far-red fluorescence. This compound is structured to incorporate into RNA strands during in vitro transcription, enabling subsequent fluorescent labeling through the aminoallyl group which can react with primary amines. The Alexa Fluor 647 moiety exhibits strong absorption and emission properties in the far-red spectrum, making it suitable for applications in fluorescence microscopy and flow cytometry where reduced background fluorescence is desired.
