文献来源:Chacon-Cruz E et al. Surfactant Modulates Calcium Response of Neutrophils to Physiologic Stimulation via Cell Membrane Depolarization. Pediatr Res. 2000 Mar;47(3):405-13. PMID: 10709743

实验方法(中性粒细胞的膜电位检测MK): 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%) ofdiOC5(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. 

注意事项

1)荧光染料均存在淬灭问题,请尽量注意避光,以减缓荧光淬灭。

2) 为了您的安全和健康,请穿实验服并戴一次性手套操作。
