combination with fluorescence imaging, we show for the first time that the lysosomalpH value increases but never decreases duringheatshock, which might result from lysosomal membrane permeabilization. We also demonstrate that this lysosomalpHrise is irreversible in living cells. Moreover, the probe is easy to synthesize, and shows superior overall analytical performance as compared to the existing
The use of soluble methylol compounds from primary or secondary amines or ammonia with formaldehyde in diazotypes improves solution compatibility and prevents coupler migration upon storage of diazotype materials. The methylol compounds may be reacted with couplers separately or added to the coating preparations.
