Ex: 642 nm. Em: 661 nm. TWO-PRO(TM)-3 is chemically equivalent to TO-PRO(R)-3 (TO-PRO(R) is the trademark of Invitrogen). TWO-PRO(TM)-3 is a carbocyanine dimer with far-red fluorescence similar to Cy(R) 5 dyes. It is cell-impermeant and easily distinguished from fluorescein and rhodamine as a nuclear counterstain...
