The following paper is good commonly used reagents. I have yet to find anything equivalent to the resources you mention however.

To join, leave or search the confocal microscopy listserv, go to: http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy ***** Good afternoon, while I am not aware of a similar on line tool for multi photon excitations, there are publications, which list "MP" excitation spectra of a number of dyes, e.g. by Bestvater et al. Ref. Bestvater, F. et al. Two-photon fluorescence absorption and emission spectra of dyes relevant for cell imaging, Journal of Microscopy, Vol. 208, Pt 2 November 2002, pp. 108115 Best wishes, Johannes > ***** > To join, leave or search the confocal microscopy listserv, go to: > http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy > ***** > > Greetings, > > For one photon excitation, the excitation and emission spectra of commonly > used fluorescent dyes can be viewed by using the following tools: > > * Invitrogen Fluorescence SpectraViewer, www.invitrogen.com > > * BD Fluorescence Spectrum Viewer, www.bdbiosciences.com > > I am wondering if we have similar tools for fluorophores with multiphoton > excitation. > > Many thanks > > Gary G.

They have a list of two-photon absorption cross-sections there that I find helpful. Its not exhaustive, but they have a number of the fluorescent proteins and alexa dyes listed there for example, and you can download the ascii data as well. http://www.drbio.cornell.edu/cross_sections.html Best wishes, James.

Probably the most comprehensive site would be at: http://www.spectra.arizona.edu/ . We've compiled all the 2P data we can find, including the DRBIO data. Simply select "2-photon cross-sections" under Dye category. We hope to incorporate the ability to download any data the user chooses, soon. This site has been assembled by Dr. Urs Utzinger at the U of A Biomedical Engineering Dept. and myself, with the code-writing help of Gary Carstensen in our Instruction/Access office, and includes much of the 1P data collected by Dr. George McNamara, U. of Miami, and myself.
Additional spectral data from optics, dyes, filters and light sources always welcome. Cheers, C Carl A.
