MycoLight™ Green JJ98 stain is an excellent green-fluorescent nuclear and chromosome counterstain that is permeant to both prokaryotic and eukaryotic cell membranes. MycoLight™ Green JJ98 stain has a high affinity for DNA and exhibits enhanced fluorescence upon binding with an excitation maximum close to the 488 nm argon laser line and fluorescence emission maximum at ~500 nm. MycoLight™ Green JJ98 stain is particularly useful as a nuclear counterstain for bacterial assays since it stains both live and dead Gram-positive and Gram-negative bacteria. It is an excellent replacement for SYTO® 9 (SYTO® is the trademark of Invitrogen).
