Role of acetic acid in collagen
WebIn this present study, collagens were prepared from tilapia bone using acetic acid and pepsin. The extracted collagen was partially characterized. Prior to extraction, tilapia bone was desalted by soaking in ethylenediaminetetraacetic acid solution and hydrochloric acid. WebLastly, cell viability studies using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assays showed the highest cell viability for the collagen-graphene-hydroxyapatite composites. In this manner, this study provided – to the field of nanomedicine – a new process for the synthesis of several nanoparticles (with low toxicity) of high interest for …

WebCollagen is soluble in acidic conditions so an acidic pH is critical for collagen stability and solubility. At a basic pH, collagen will polymerize and form a hydrogel. This will also happen if too high concentrations of collagens are used. Equally, as collagens are more unstable than other proteins, assays should be performed at <10⁰C.
