實(shí)驗(yàn)方法(中性粒細(xì)胞的膜電位檢測(cè)): Neutrophils were buffered at pH 7.4 in decreasing external [NaCl] and increasing external [KCl] to maintain the total external cation concentration equal to 150 mM in a stirred, temperature-controlled cuvette (24°C) at excitation wavelength of 460 nM and emission wavelength of 507 nM. Dye response (ΔF%) of DIOC5(3) (225 nM) in the presence of the K+ ionophore valinomycin (10 μM)was calibrated to ΔΨ by the equation MATH 2 where R = ideal gas constant, T = temperature (Kelvin), and F = faraday's constant.
注意事項(xiàng):
1. 熒光染料均存在淬滅問題,請(qǐng)盡量注意避光,以減緩熒光淬滅。
2. 為了您的安全和健康,請(qǐng)穿實(shí)驗(yàn)服并戴一次性手套操作。
