ANS-Na (8-苯胺基-1-萘磺酸鈉) 是一種疏水熒光染料，ANS 用于研究蛋白折疊/去折疊途徑的中間狀態(tài)的重要染料。也可用于檢測(cè)與蛋白聚集有關(guān)的構(gòu)象變化。ANS在水溶液中是非熒光的，但與BSA（牛血清白蛋白）和變性蛋白結(jié)合后發(fā)出強(qiáng)烈熒光。它可用于檢測(cè)血清白蛋白。ANS主要與暴露于溶劑的非極性（疏水性）位點(diǎn)相互作用。

性狀Solid，power

儲(chǔ)藏條件 Storage conditions4℃條件下存儲(chǔ),-4℃存儲(chǔ)更佳

PH 對(duì)ANS探針的影響：

(A) Effect of pH on the binding of 8-anilino-1-naphthalenesulfonic acid (ANS) with CdGSTM1. The binding of ANS (200 μM) with CdGSTM1 (4 μM) at pH 1.0-10.0 was monitored by excitation at 380 nm (bandwidth 2.5 nm) and emission spectra collected from 400-600 nm (bandwidth 5 nm) at 22?C. (B) Rayleigh light scattering measurements of CdGSTM1 (0.1 mg mL-1 ) were obtained at 500 nm wavelength at pH 1.0-10.0.
