Figure 4From: Single fluorescent protein-based Ca2+sensors with increased dynamic rangeCa2+ response to a prolonged glutamate treatment in cortical neurons. Fluorescent signals of Case12 (gray solid line, excitation at 490 nm, 515–565 nm emission filter) and fura-2FF (black dashed line, ratio of 340 nm and 380 nm excited green fluorescence, 505–530 nm emission filter) are shown.Back to article page
