Custom LSR-II - laser options?

The 532nm @150 mW works quite well with mCherry and mTomato; we have  
not had the chance to use mPlum.  If you choose this option, you will  
need to either use a narrower than standard detection filter for  
FITC, or else buy a 532 notch filter. We have done the latter, and it  
works quite will.

BD will also configure your system with a 561 nm laser. The power on  
these diodes (50 mW) is less than the green, but they match the  
excitation of PE and its tandems, and the new fluorescent proteins  
better. I have not seen any comparison data to be able to say one  
works better than the other.
