Thank you for your reply! Indeed, firstly I wanted to suggest also to use Texas Red with TRITC. However when I looked closer at the emission spectra, it seemed to me that there is quite a "bleeding" of the TRITC into the Texas Red. However this depends also on the staining intensities and the filters available on the microscope. http://www.mcb.arizona.edu/ipc/fret/index.html The DyLight 594 however is still excited (to about 40%) with the laser at 542nm. I thought therefore this might be the safer option. https://www.abcam.com/ps/CMS/Images/DL_594_orange[1]378px302px.jpg It is however up to you to decide. Either option you will chose, we will continue to support you. We will also reward you with points for discounts/amazon vouchers if you can provide your feedback with an image. I hope this information is helpful. Please do not hesitate to contact us again should you have further questions. Merry Christmas and happy new Year to you as well!

Thank you very much for your inquiry. Indeed we do have a number of antibodies which can be suitable for your application. Please find here below a selection. I have only proposed pre-absorbed antibodies, as they will help to reduce background in immunohistochemistry, especially when doing double stainings. We do also have other formulations of many of these antibodies. For example, we do have antibodies also produced in donkey, against the Fc region or as an F(ab')2. Please do let me know if you have any preference in these regards and I'll be happy to include them in the selection. I have excluded in this list fluorochromes who could interfere with the GFP staining. If this would not matter however, please let me know. Indeed, the request formulated is rather specific. The best option I can propose is, to use the Cy3.5 conjugated anti guinea pig ab6966, with the DyLight 594 conjugated anti rabbit antibody ab96921. I would expect this to provide a good double staining. Please check however with your microscope specialist as well, whether this is an option for you.

DyLight594: max excitiation at 591 max emission at 616 -we do have the anti guinea pig antibody in this conjugation, unfortunately not preabsorved. It would therefore need to be tested first. It is the ab96961. We might can provide you with a testing offer if you would be interested in this option. -donkey anti rabbit IgG H+L, preabsorbed: ab96921 Click here (or use the following: https://www.abcam.com/index.html?datasheet=96921). As an alternative to an already conjugated antibody, I can also recommend to use either a biotynilated antibody or an unconjugated antibody. In those cases, you would either need an avidin/streptavidin in the right color or a correct conjugation kits (e.g. PerCP, tandem dyes). For the conjugation kits, I can recommend our easylink conjugation kits, very fast and easy to use: www.abcam.com/easylink Please do not hesitate to contact can we help or advise you further. We do have also a poster "guide to fluorochromes", which I can recommend to consult or to download: https://docs.abcam.com/pdf/immunology/fluorochrome_guide.pdf Alternatively, we do also have a poster on the DyLight antibodies. https://docs.abcam.com/pdf/general/DyLight_flyer.pdf I hope this information is helpful. Many season greetings!
