General description

ProClin™ preservatives are water-soluble preparations of biocides that are generally used to increase the shelf life of reagents. ProClin™ 300 comprises of 3% of 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT) and 2-methyl-4-isothiazloin-3-one (MIT) in a salt-free proprietary glycol containing an alkly carboxylate stabilizer. It has a recommended working pH range as 2.5 - 8.5.

Application

For use in IVD Manufacturing
ProClin™ 300 is suitable for preparation of different buffers like ELISA buffer, sample and substrate dilution buffers for Single-Molecule Arrays (Simoa assay) and Immunoenzymatic assay. Additionally, Proclin™ may be used in preparing storage buffer to store beads coupled with coronavirus nucleocapsid protein for the serological multiplex assay.
ProClin™ biocides preservatives are immediately microstatic upon contact with microbial organisms as a result of their ability to quickly penetrate cell membranes and inhibit specific enzymes crucial to cellular respiration. Multiple specific sites of ProClin™ toxicity prevent microorganisms from developing high levels of resistance, making ProClin™ highly efficient even over extended storage periods of your IVD components.

Biochem/physiol Actions

ProClin™ products contain active substances like CMIT and MIT which inhibit the Krebs cycle at four different check points, the enzymes pyruvate dehydrogenase, α-ketoglutarate dehydrogenase, succinate dehydrogenase, and NADH dehydrogenase. The inhibition of Krebs cycle leads to effective broad-spectrum biocidal activity against bacteria, fungi, and yeast.
