Proclin™ biocide preservative inhibits microbial Kreb cycle in several places

ProClin™ preservatives attack the Krebs cycle at four key points: the enzymes pyruvate dehydrogenase, α-ketoglutarate dehydrogenase, succinate dehydrogenase, and NADH dehydrogenase. Because all bacteria and fungi possess at least part of the Krebs cycle, they are broad spectrum in their activity.

ProClin™ preservatives are readily available in convenient pack sizes suitable for all manufacturing processes and volumes. Along side our four formulations, we also provide ProClin™ support products like a ProClin™ reference standard and a ProClin™ variety kit, useful in testing and evaluating the use of ProClin™ preservative within a specific diagnostic reagent or assay.

The ProClin™ Variety Kit (48119-U) contains 5 mL bottles of all four formulations and is an excellent tool for evaluating the suitability of ProClin™ products for their specific applications. See the characteristic differentiators between the formulations in our technical chart. Want to see how ProClin™ preservatives benefit your reagent? Request a sample.

Despite the enhanced safety profile of ProClin™ products, a study from an independent lab has shown equivalent or improved efficacy when compared to top alternatives like thimerosal and sodium azide. 

ProClin™ preservatives are restricted to use in IVD assay development and are intended for use in IVD manufacturing only. Contact your local regulatory body for specific usage and handling guidelines.


We provide ProClin™ preservative product range with different characteristic formulations in multiple pack sizes to suit your specific needs.
