Figure 2: (A) Epi-illumination of a rat skinned myocyte treated with anti-α-actinin antibody-QDs excited by blue light during ADP-SPOC (see [25] for composition of the ADP-SPOC solution). Note the clear striations along the myocyte. (B) Same myocyte as in the (A) during ADP-SPOC, observed under the bright field. Observations were conducted under the same optics system as described in [25], and the temperature was maintained at 25°C. See Supplementary Videos 1 and 2.
