Fig. 1From: Sustained release of rhBMP-2 from microporous tricalciumphosphate using hydrogels as a carrierComparison of the release kinetics of three different hydrogels regarding FITC Protein A measured by fluorescence reader in a 28-day-trial (incubation at 37 °C, Phosphate buffer saline changed completely at each measuring point): The alginate with external Ca2+ source reveals a significantly reduced burst release, while the second release phase is prolongedBack to article page
