David, According to Amersham, Cy7 was pulled off the market because there
were instability problems with unconjugated Cy7.  They are trying to
resolve the instability issues.  You might be able to get a sample of the
original Cy7, if they have any left.

Indocyanine green, with a spectrum shifted further red, was
recently suggested to me.  Has anyone tried it for microinjection or
patch clamping?

Regards,
Glen
