Bangs Labs Beads

Hello all,

I've heard a rumor (from Dr. Mario himself) that there are amine-binding beads from Bangs
Labs that can be used to compensate viability dyes.  Does anyone know which beads they
are, or has anyone used something similar?  I'd love to be able to use them in apoptosis
experiments instead of having to kill some cells every time.  Does anyone know if they
work for Annexin as well? Thanks for the help!
