Accurate values of stability constant of Ca(2+)-murexide complex.
Khan TK, Gupta-Bhaya P. Khan TK, et al. Talanta. 1997 Nov;44(11):2087-94. doi: 10.1016/s0039-9140(97)00078-7. Talanta. 1997. PMID: 18966957
In published reports, the values of stability constants of 1:1 complex of Ca(2+) and the dye ammonium purpurate (murexide) were not determined under controlled conditions and were not properly corrected for the binding of Ca(2+) with ions of buffer used to maintain pH and …

Myoplasmic calcium transients in intact frog skeletal muscle fibers monitored with the fluorescent indicator furaptra.
Konishi M, Hollingworth S, Harkins AB, Baylor SM. Konishi M, et al. J Gen Physiol. 1991 Feb;97(2):271-301. doi: 10.1085/jgp.97.2.271. J Gen Physiol. 1991. PMID: 2016581 Free PMC article.
Baylor. 1991. J. Gen. Physiol. 97:245-270) for fibers injected with purpurate-diacetic acid (PDAA). The latter difference may be explained, at least in part, by the likelihood that the effective dissociation constant of furaptra for Ca2+ is larger in vivo than in vitro, ow …

Calcium signals recorded from two new purpurate indicators inside frog cut twitch fibers.
Hirota A, Chandler WK, Southwick PL, Waggoner AS. Hirota A, et al. J Gen Physiol. 1989 Oct;94(4):597-631. doi: 10.1085/jgp.94.4.597. J Gen Physiol. 1989. PMID: 2614368 Free PMC article.
Two new Ca indicators, purpurate-3,3'diacetic acid (PDAA) and 1,1'-dimethylpurpurate-3,3'diacetic acid (DMPDAA), were synthesized and used to measure Ca transients in frog cut muscle fibers. These indicators are analogues of the purpurate components of murexide and …

Effect of fura-2 on action potential-stimulated calcium release in cut twitch fibers from frog muscle.
Pape PC, Jong DS, Chandler WK, Baylor SM. Pape PC, et al. J Gen Physiol. 1993 Aug;102(2):295-332. doi: 10.1085/jgp.102.2.295. J Gen Physiol. 1993. PMID: 8228913 Free PMC article.
Cut fibers (striation spacing, 3.6-4.2 microns) were mounted in a double Vaseline-gap chamber and studied at 14-15 degrees C. One or both of the Ca indicators fura-2 and purpurate-3,3' diacetic acid (PDAA) were introduced into the optical recording site by diffusion from t …

A simple flow-injection spectrofluorimetric method for the determination of mercury.
Andac M, Asan A, Tinkilic N, Isildak I. Andac M, et al. J Fluoresc. 2007 Jul;17(4):401-5. doi: 10.1007/s10895-007-0182-4. Epub 2007 Apr 25. J Fluoresc. 2007. PMID: 17457665
A highly sensitive flow-injection spectrofluorimetric method is presented for the rapid and simple determination of Hg (II) in environmental and pharmaceutical samples. Murexide (ammonium purpurate) was used as the fluorescence reagent in the carrier stream. ...

A novel spectrofluorimetric method for the ultra trace analysis of nitrite and nitrate in aqueous medium and its application to air, water, soil and forensic samples.
Biswas S, Chowdhury B, Ray BC. Biswas S, et al. Talanta. 2004 Oct 8;64(2):308-12. doi: 10.1016/j.talanta.2004.02.018. Talanta. 2004. PMID: 18969604
The method is based on the quenching action of nitrite on the native fluorescence of murexide (ammonium purpurate) [lambda(ex)=349.0nm, lambda(em)=444.5nm] in the acid range of 0.045-0.315 (M) H(2)SO(4). ...
