Description

5-IAF (5-Iodoacetamidofluorescein) is an idoacetamide derivate of fluoresceine. 5-IAF can be used as fluorescent probe that labels proteins and other molecules having free thiols (cysteine side chains)[1][2].

In Vitro

8 μM GSH sample solution is derivatized with 8, 80, 200, 400, 800, 1600, 2000, 2500 μM 5-IAF, respectively and analyzed with CE-LIF. The highest signal intensity is obtained with 400 and 800 μM 5-IAF[2].

HepG2 cells are lysed in 1 mL 2% acetonitrile in water, and transfered to a 1.5 mL centrifuge tube. An additional 200 µL 2% acetonitrile is used to rinse the dish and combined with the cell extract. To measure the free GSH concentration, three aliquots of 80 µL cell extract are immediately transferred to 0.5 mL centrifuge tubes after a quick mix. Then 20 µL 50 µM NAC is added, followed by the addition of 100 µL 400 µM 5-IAF to the mixture. The derivatization is conducted at room temperature in dark for 1 h, after which the mixtures are centrifuged at 9000× g for 5 min to sediment the insoluble proteins. 10 µL supernatant is diluted 100× with water and analyzed immediately by CE-LIF[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
