Dojindo,NOC 5/50/N380,NOC 是稳定的 NO-胺复合物
2022年5月1日一氧化氮释放1。使用 0.1 M NaOH 制备 10 mM NOC 库存溶液。由于NOC原液不稳定，所以放在冰浴上一天用完。 2．将适量的 NOC 储备溶液添加到要释放 NO 的样品溶液中。为保持样品溶液的 pH 值，NOC 储备溶液的体积不应超过样品体积的 1/50。样品溶液应具有足够的缓冲作用。加入 NOC 储备溶液后，NO 将立即释放。
Table 1 pH Dependency of NO Release at 37ºC
Prepare 10-50 mM NOC solution with 0.1 M NaOH solution. Then add enough NOC solution to the cell culture to obtain a suitable concentration of NOC in cell culture. If the pH of the culture solution changes, use higher concentration of NOC.
NOC 5: 40 mg per 100 ml 0.1 M NaOH (2.2 M NOC 5)NOC 7: 70 mg per 100 ml 0.1 M NaOH (4.3 M NOC 7)NOC 12: 27 mg per 100 ml 0.1 M NaOH (1.5 M NOC 12)NOC 18: 20 mg per 100 ml 0.1 M NaOH (1.2 M NOC 18)
The stock solution will lose 5% of its NOC activity per day, even when stored at -20oC. Please prepare fresh solution prior to use and keep the solution on an ice bath during the experiment. VI-1. Nitric Oxide Research: NO Donors
Prepare 20 mM NOC stock solution with 0.1 M NaOH. Warm PBS at 37ºC. Add 100 ml NOC solution to 1.9 ml PBS. Using a UV spectrophotometer, immediately start measuring its absorbance at the maximum wavelength of the NOC. Continue measuring until no further spectra changes are observed.
Yes. Please review the papers by Shibata and colleagues (1995, 1996).
The amount of NO released in the solution should be the same if the pH and temperature are the same. However, the activity of NO may be different in vivo because of other reactive components such as thiol compounds and heme.
Dojindo细胞分析
细胞活力和细胞毒性测定用于药物筛选和化学物质的细胞毒性测试。Dojindo开发了高度水溶性的四唑盐，称为WST。WST-8是高度稳定的WST，用于Cell Counting Kit-8（CCK-8）。由于WST-8甲maz是水溶性的，因此不会形成晶体。因此，不需要诸如MTT测定的增溶过程。此外，CCK-8的检测灵敏度高于其他四唑盐，例如MTT，XTT，MTS或WST-1。
