预算内主要比较批间差、货期和包装，不要只看单支价格。问清是否含异丙醇、能否常温或冷链运输、是否有纯度/溶解性批次数据。可让供应商提供小样试用，验证对大鼠肝脏、脾脏裂解液的抑制效果。国产小包装通常货期快，适合动物房批量补充。

批量采购不要只买大瓶粉末反复受潮，建议选小规格或预分装粉末。毒性方面索要MSDS，确认危化品包装和运输资质，到货后做领用台账。动物样品多时把母液分装成单次用量，避免反复开盖和冻融。

国产PMSF现在的纯度、溶解性普遍能替代进口，但首次采购建议先索要COA，收到后配成100mM异丙醇母液观察是否完全澄清、无色。再用同样样品做国产与进口的抑制对照，确认条带无差异后批量。国产货期一般更灵活，适合月度采购。

自己配比买母液更划算，尤其每月几十毫升用量。按174.2mg加到10ml异丙醇中可配100mM母液，分装-20保存。买母液省事但单次成本较高，还要确认溶剂体系和运输条件。实验室有通风橱和称量条件的，建议自己配、小体积分装。
