Figure 1.

Figure 1

Figure 1A The onset of turbidity in 1 mL chitosan-GP solutions raised to 37°C is not significantly affected by the addition of up to 3.75 mg of BSA. Transition to 50% of maximal turbidity changes occurs between 13 and 15 minutes for all preparations. The chitosan content of these gels is 15 mg.

Figure 1B The thermogelling transition of chitosan-glycerophosphate as assessed by the gel-tipping technique demonstrates gradual prolongation of transition time with the inclusion of progressively higher amounts of BSA (ANOVA, p < 0.01). Bracketed groups are not significantly different (Dunn’s, α = 0.05). Data are shown for gelation time for varying amounts of added BSA (mean + s.e.m., n = 4).
