荧光

λex 638 nm; λem 656 nm in 0.1 M phosphate pH 7.0

适用性

corresponds for coupling to amines
suitable for fluorescence

一般描述

Tracy 645 is a newly developed NIR fluorescent dye. The spectral range above 650 nm is of particular interest in biology analysis and imaging due to the reduced background and improved sensitivity.
Tracy 645 is a highly water-soluble and stable dye.
