The potency differs In accordance with bacterial species and strain; and by solubility and molecular weight. The more potent endotoxins are Those people of the highest molecular Lipid-A weight and those which might be most disaggregated.
In combination with the steps pointed out for PW system validation, WFI system validation includes yet another focus on the technology and control of high-high quality water meeting the particular needs for WFI. The validation approach commonly involves in depth tests and documentation of the various levels, for example pretreatment, distillation, or other validated methods employed for WFI creation.
