Alexa Fluor™ 568 Hydrazide, for microinjection - FAQs

What dye can I use that is non-reactive and can show an injection site?

The non-reactive Alexa Fluor and Alexa Fluor hydrazide derivatives may be used for injection site visualization. Other options include the fluorescent polystyrene microspheres, FluoSpheres, and dye-conjugated dextrans. The hydrazide derivatives and 'fixable' dextrans are retained by cross-linking using an aldehyde-based fixative.
