1、PBS缓冲液配方不管是免疫组化，还是细胞培养中，常用到PBS缓冲液，下面是常用配方，供大家参考。用于细胞培养的PBS需含有氯化钾称取8gNaCl、0.2gKCl、1.44gNa2HPO4和0.24gKH2PO4,溶于800ml蒸馏水中，用HCl调节溶液的pH值至7.4，最后加蒸馏水定容至1L，灭菌即可。0.01MPBS缓冲液称取NaCl 8g，KCl 0.2g，Na2HPO4•12H2O 3.63g, KH2PO4 0.24g，溶于900ml双蒸水中，用盐酸调pH值至7.4，加水定容至1L，常温保存备用。一般免疫组

2、化用PBS，主要用来清洗，都只包含Na2HPO4•12H2O（磷酸氢二钠）和NaH2PO4•2H2O（磷酸二氢钠）两种组分，母液的配制： 0.2M Na2HPO4：称取 71.6g Na2HPO4-12H2O，溶于 1000ml 水0.2M NaH2PO4：称取 31.2g NaH2PO4-2H2O，溶于1000ml 水各种浓度PB(pH=7.4)的配制：先配 0.2M PB (pH=7.4，100ml)：取19ml 0.2mol/L的 NaH2PO4， 81ml 0.2mol/L 的 Na2HPO4, 即可。然后

3、 只需将0.2M PB (pH=7.4)按相应比例适当稀释 即可，如：0.1M PB（PH=7.4） ：取 500ml 0.2M PB，加水稀释至 1000ml 即可。0.01M PB （PH=7.4）：取50ml 0.2M PB，加水稀释至 1000ml 即可。0.02M PB （PH=7.4）：取100ml 0.2 M PB，加水稀释至 1000ml 即可。 若需要 NaCL 的话，加入 NaCL 至0.9%（g/100ml）即可。 另：其它各种另 PH值的 0.2M PB（100ml)配方 ：pH
