Comparison of the apparent solubilities of samples
of TM-a, TM-b,
PM, and DM prepared at different initial concentrations. The apparent
solubility of the peptides in PBS buffer at pH 7.4 is represented
by the absorbance at 280 nm and was measured after 7 days: black for
TM-a, red for TM-b, green for PM, and yellow for DM. The absorbance
was measured after centrifugation at 24 °C for 20 min at 1.75
× 104g.
