Phosphate citrate buffer ph range
WebMay 25, 2024 · In a separate experiment, the citrate buffer (50 mM, pH 5.4) was replaced by phosphate buffer (100 mM, pH 7.0) keeping 20% v / v ethanol. No significant difference (t-test, p > 0.05) in terms of protein content and residual activity were observed between the particles obtained at pH 5.4 and pH 7 (see Supporting Information, Figure S6).
