[edit] Quartenized nitrogen

There is a statement about both nitrogens being quartenized. This is not true. Comments please? --Kupirijo (talk) 11:51, 26 December 2007 (UTC)

I also checked the article cited and there is a mention of quartenized bases. I think there is a mistake in the article. --Kupirijo (talk) 22:44, 26 December 2007 (UTC)

[edit] Use in CD-Rs

Cyanine dyes are still used in the more expensive CD-Rs. Even in my own experience, discs using Cyanine dye (Taiyo Yuden's, Maxell CD-R Pro, etc.) have much better burns and hold up much better than those using pthalocyanine (the other dye used in CD-Rs). All the more expensive media use Cyanine. I emailed Maxell and they informed me that the CD-R Pro uses Cyanine and all their other CD-Rs use pthalocyanine. According to Maxell, their CD-R Pro are designed for 100 years archival [1]. Chris01720 (talk) 15:02, 28 January 2008 (UTC)

[edit] Quantum Yield

I think the quantum yield of Cy3 is closer to 0.04. Anyone know where the 0.15 number came from? [2] KristinLee (talk) 20:08, 2 June 2008 (UTC)
