Choosing filter configurations for Qdots in Flow

Joanna,

Actually, the best strategy for each Qdot detector is the use of a sharp
dichroic mirror with a wide band pass filter. After much trial and error the
attached filter configuration illustrates this point. You can also visit our
web site at; 
http://www3.niaid.nih.gov/labs/aboutlabs/VRC/flowCytometryCoreLaboratory/
for additional information. If your current system has a green laser, the
QD525 will be very dim because of the narrow 515/20 filter. I would
recommend using QD545 with the filters as listed in the attachment.
