Figure 3: Quantification of generic protein released from pure PRGF scaffolds over 35 days. *indicates significant differences, p < 0.05, for days 1 and 28 when compared to all other time points for each material, but not each other. #indicate statistically significant differences, p < 0.05, between days 1, 4, and 35 when compared to other time points, but not each other. Minimum level of detection was 17 μg/ml.
