In this paper, the units for pressure were incorrectly given, and should have been mN m−1 as they refer to surface pressure. This affects Figures 1, 2 and 3, as well as two parts of the text on page 640 (in the penultimate paragraph on the left and first paragraph on the right). The corrected figures are given below.

Figure 1.

Kinetic adsorption process for the incorporation of rhodopsin to the air/water interface at different DDHA-PC initial pressures: 1 mN m−1 (curve 4), 6.1 mN m−1 (3), 10.4 mN m−1 (2) or absence of DDHA-PC (1). DDHA-PC stock solution was prepared and added drop wise to the subphase (PBS, pH 7.4) until the desired lipid pressure was achieved. The final concentration of rhodopsin was 1.4 nM.

Figure 2.

Determination of rhodopsin MIP. Plot of the surface pressure increase (Δπ) caused by rhodopsin against lipid initial surface pressure (πi) to determine the MIP of rhodopsin with DDHA-PC monolayers, by extrapolating the curve to the x-axis. The subphase was PBS (pH 7.4), and the final concentration of rhodopsin was 1.4 nM.

Figure 3.

Plot of the equilibrium adsorption pressure (πe) of rhodopsin against initial monolayer surface pressure (πi) of DDHA-PC. The subphase was PBS, pH 7.4, and the final concentration of rhodopsin was 1.4 nM.
