five buffer systems are investigated at pH 8.5: tris, carbonate, hepes, borate, and glycine buffers, and the lowest catalytic activity of alkaline phosphatases at equal pH is observed in the borate buffer. The highest specific activity, is observed in the buffer solution of tris-(oxymethyl)-aminomethane-HCl | Bos taurus |
