摘要: Knowledge of the interactions between polymer and protein is very important to fabricate potential materials for many bio-related applications. In this regard, present work investigated effect copolymers on conformation thermal stability bovine serum albumin (BSA) with aid biophysical techniques such as fluorescence spectroscopy, circular dichroism (CD) spectroscopy differential scanning calorimetry (DSC). comparison that copolymer PGA-1.5, our results reveal PGA-1, which has a lower PEGMA/AA ratio, shows greater influence BSA. Copolymers induced unfolding polypeptide chain BSA, was confirmed from loss in negative ellipticity CD spectra. DSC showed addition PGA-1 PGA-1.5 (0.05% (w/v) decreased transition temperature by 14.8 11.5 °C, respectively). The study behavior response changes chemical composition synthetic polymers are significant various biological applications enzyme immobilization, separations, sensor development stimuli-responsive systems.
