I am Isabel Romero, a PhD student, and I am working in the Department of Pharmacology, Faculty of Pharmacy, University of Granada, Spain. I am trying to measure K+ changes inside of some intestinal cell lines. For that, I need to use a Potassium Indicator dye. People use PBFI, but it requires UV excitation and we don´t have it. An alternative could be the Asante Potassium Green 1 and 2. I am trying to read something about that, but I guess there is not any publication untill now. I am wondering if some of you have done this staining or have some suggestion. Thank you very much! Best regards, Isabelius. Isabel Romero Calvo, PhD student.

Teflabs recently introduced APG3 and 4 with better selectivity for K. Of these, APG4 seems to have somewhat lower affinity (which is good). We just published a paper in Apoptosis (Kasim et al) available online where we show the expected decrease of K+ in apoptotic cells (that picture is in the Supplement). We have also done some work with APG using FACS. In short, the dye works but quantification may be a little tricky. Please contact me off list for more info.

APG are supposed to be much more specific for K. -----Original Message----- From: Confocal Microscopy List [mailto:[hidden email]] On Behalf Of Kilgore, Jason Sent: Tuesday, January 29, 2013 12:32 PM To: [hidden email] Subject: Re: Asante Potassium Green ***** To join, leave or search the confocal microscopy listserv, go to: http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy ***** Mike, How do APG3 and APG4 compare to PBFI, in your experience, in terms of signal change, sensitivity, and usage?
