Methyl purple, an exceptionally sensitive monitor of chloroplast photosystem I turnover: physical properties and synthesis.
Graan T, Ort DR, Prince RC. Graan T, et al. Anal Biochem. 1985 Jan;144(1):193-8. doi: 10.1016/0003-2697(85)90104-6. Anal Biochem. 1985. PMID: 3885784
The specific molar absorption coefficients of both the anionic and protonated forms of methyl purple have been determined. The oxidation-reduction midpoint potential of methyl purple over the pH range 3 to 12 was also determined by polarographic method …

Quantitation of the rapid electron donors to P700, the functional plastoquinone pool, and the ratio of the photosystems in spinach chloroplasts.
Graan T, Ort DR. Graan T, et al. J Biol Chem. 1984 Nov 25;259(22):14003-10. J Biol Chem. 1984. PMID: 6389539 Free article.
Our investigations were based on a new experimental technique made possible by the use of a modified indophenol dye, methyl purple, the reduction of which provides a particularly sensitive and accurate measure of electron transfer. ...

The reduction of artificial electron acceptors at sub-zero temperatures by chloroplasts suspended in fluid media.
Cox RP. Cox RP. Biochim Biophys Acta. 1975 Jun 17;387(3):588-98. doi: 10.1016/0005-2728(75)90096-1. Biochim Biophys Acta. 1975. PMID: 1138892
The reduction of oxidised 2,3,5,6-tetramethyl-p-phenylenediamine could be measured at -25 degrees C in 40% (v/v) ethylene glycol. Using an acceptor with a high extinction coefficient, methyl purple (a derivative of 2,6-dichlorophenolindophenol) it was possible to ob …

Involvement of superoxide dismutase in heat-induced stimulation of photosystem I-mediated oxygen uptake.
Lajkó F, Kadioglu A, Garab G. Lajkó F, et al. Biochem Biophys Res Commun. 1991 Jan 31;174(2):696-700. doi: 10.1016/0006-291x(91)91473-p. Biochem Biophys Res Commun. 1991. PMID: 1993064
Spectroscopic techniques, oxidation of dichlorophenolindophenol (donor side) and reduction of NADP or methyl purple (acceptor side), showed no indication of an increased activity of photosystem I electron transport. ...
