Do you offer VIC or NED dyes?

IDT does not offer VIC or NED dyes. However we do offer dyes with similar spectral characteristics: Yakima Yellow is a direct substitute for VIC, and TAMRA is an alternative for NED. In addition, the ATTO dyes are perfect substitutes for dyes such as ROX™, VIC®, LIZ®, and Alexa Fluor® dyes. See a list of dyes and dye alternatives.
