Effect of protein molecular weight on bulk adhesion strength. The bonding of ELP[KEY4-n] with 24, 48 and 96 pentapeptides was tested. To see the effect of a mixture of molecular weights, a 1 : 1 : 1 molar ratio of the three proteins was also tested. Generally, adhesion strength increased with molecular weight. The mixture of molecular weights resulted in a similar adhesion strength to that of either of the two longest proteins tested alone. Groups with identical letters are statistically similar (p> 0.05) when determined by one-way ANOVA followed by Tukey's HSD post hoc analysis.
