4、ol/L的 NaH2PO4和 0.2mol/L的 Na2HPO4，两者按一定比例混合即成 0.2mol/L的磷酸盐缓冲液（PB），根据需要可配制不同浓度的PB 和 PBS。（1）0.2mol/L的 NaH2PO4；称取 NaH2PO4.2H2O 31.2g(或 NaH2PO4 H2O 27.6g)加重蒸水至 1000ml溶解。（2）0.2mol/L的 Na2HPO4：称取 Na2HPO4.12H2O 71.632g（或 Na2HPO4 7H2O 53.6g或 Na2HPO4 2H2O 35.6g）加重蒸水至1000ml溶解。（3）0.2mol/L pH7.4的 PB 的配制：取19ml 0.2

5、mol/L的 NaH2PO4和 81ml 0.2mol/L的Na2HPO4 12H2O,充分混合即为0.2mol/L的 PB（pH 约为 7.4 7.5）。若 pH 偏高或偏低，可通过改变二者的比例来加以调整，室温保存即可。0.2mol/L磷酸盐缓冲液（pH5.7 8.0）pH 0.2mol/L NaH2PO4(ml)0.2mol/L Na2HPO4(ml)5.7 93.5 6.5 5.8 92.0 8.0 5.9 90.0 10.0 6.0 87.7 12.3 6.1 85.0 15.0 6.2 81.5 18.5 6.3 77.5 22.5 6.4 73.5 26.5 6.5 68.5 3
