Figure Lengend Snippet: Effects of biotin concentration on swelling properties in avidin swelling buffer. (A,B) Fold changes in swelling ratios compared to day 0 time point of hydrogels biotinylated with 0, 0.1, or 1 FME NHS-dPEG 12 -biotin in (A) 17.1 μM avidin or (B) 85.5 μM avidin for 7 days. n = 3, mean ± SD. Statistical significance between different FME hydrogels determined using two-way ANOVA with Tukey's post-hoc test (0 FME vs. 0.1 FME: ** p < 0.01, *** p < 0.001; 0 FME vs. 1 FME: + p < 0.05, ++ p < 0.01; 0.1 FME vs. 1 FME: # p < 0.05). (C–E) Fold changes in swelling ratios of hydrogels with (C) 0 FME, (D) 0.1 FME, or (E) 1 FME NHS-dPEG 12 -biotin, in either 17.1 or 85.5 μM avidin solutions, over 7 days. n = 3, mean ± SD. No statistical significance resulting from different avidin concentrations, determined using two-way ANOVA with Sidak's post-hoc test. Statistical significance between time points determined using two-way ANOVA with Tukey's post-hoc test ( % indicates p < 0.05 compared to the previous day).
Article Snippet: After estimating the number of amine groups present as described above, a 25 mM stock solution of NHS-dPEG 12 -biotin was prepared in DMSO (Sigma-Aldrich).
