Dear All, I need some advice in setting up for a very important experiment coming up. Has anyone used the fluorophore PerCP CY5.5 with success for confocal microscopy? Any experience with autofluorescence in this wavelength or whether this fluorophore is a severe bleacher etc.? I want to do 5 or 6 color on a Zeiss LSM710 and am thinking about the following, I would love your feedback.
Thank you in advance, Andrea -------------------------------- Andrea T. Hooper, PhD |

Alexa405 has been very dim and bleach-prone in my hands. I think if
you call Invitrogen they might tell you that "Marina blue" is a better option, I remember Mike Ignatius posting something to that effect in the past couple of years. Good luck. -Esteban On Tue, Nov 3, 2009 at 4:16 PM, Andrea Hooper <[hidden email]> wrote: > Dear All, > I need some advice in setting up for a very important experiment coming up. > Has anyone used the fluorophore PerCP CY5.5 with success for confocal > microscopy?

Hi Andrea,
I actually did 5-color staining on a Zeiss LSM510, with Alexa 405, Alexa 430, Alexa 488, Alexa 555 and Alexa 647. http://jeb.biologists.org/cgi/content/full/211/16/2584 (Figs 6 and 8 are 5-color staining) I used Alexa 405 and 430 in the above paper, but later I found that Pacific Blue is better than Alexa 405, and Pacific Orange is better than Alexa 430 (brighter and more stable, although not as stable as other Alexa dyes, such as Alexa 488, 555 and 647). I did not check Marina blue yet. I did not compare Alexa 647 and Alexa 633, but I have heard that Alexa 647 is better than Alexa 633, even if with 633 nm laser.

It has been my experience that AlexaFluor647 is brighter than AF633
even with a 633 laser. The extinction coefficient of AF647 is more than 2x that of AF633 so that compensates for the less-than-ideal laser. In addition our standard "far red" emission filters better match the emission spectrum of AF647 and I suspect the quantum yield of AF647 is higher too, though the last time I checked the Invitrogen website that specification was not given. -Esteban 2009/11/4 Junya HIROI <[hidden email]>: > Hi Andrea, > > I actually did 5-color staining on a Zeiss LSM510, with > Alexa 405, Alexa 430, Alexa 488, Alexa 555 and Alexa 647. > > http://jeb.biologists.org/cgi/content/full/211/16/2584 > (Figs 6 and 8 are 5-color staining) > > I used Alexa 405 and 430 in the above paper, but later I found that Pacific > Blue is better than Alexa 405, and Pacific Orange is better than Alexa 430 > (brighter and more stable, although not as stable as other Alexa dyes, such > as Alexa 488, 555 and 647).

Jason Kilgore, here at Probes, did a careful analysis a while back using Hg arc lamp illumination. We can't comment on what a 405 laser might do as we don't have one on our scopes.
For Brightness (Flow folks care about this the most) Pacific BlueT > Marina Blue® > Alexa Fluor® 405. But for photostability, which imagers care the most about: w/out antifade Marina Blue® > Alexa Fluor® 405 > Pacific BlueT With our antifades, Prolong® Gold or Slowfade® gold Marina Blue® >> Alexa Fluor® 405 > Pacific BlueT. Thus Marina Blue® is preferred over the Alexa Fluor® 405 for imaging applications.
