Polyaminopropyl biguanide (PAPB) is a positively charged antimicrobial polymer and cosmetic preservative. Polyaminopropyl biguanide inhibits the growth and division of negatively charged microorganisms via charge-based adsorption. Polyaminopropyl biguanide exhibits broad-spectrum in vitro activity against foodborne microorganisms and postharvest fruit pathogens. Polyaminopropyl biguanide can be used in studies related to citrus postharvest diseases and foodborne bacterial infections.

Beschreibung

Polyaminopropyl biguanide (PAPB) is a positively charged antimicrobial polymer and cosmetic preservative. Polyaminopropyl biguanide inhibits the growth and division of negatively charged microorganisms via charge-based adsorption. Polyaminopropyl biguanide exhibits broad-spectrum in vitro activity against foodborne microorganisms and postharvest fruit pathogens. Polyaminopropyl biguanide can be used in studies related to citrus postharvest diseases and foodborne bacterial infections[2].

In Vitro

Polyaminopropyl biguanide (0.125-0.25%) significantly enhances the tensile strength and elongation at break of PEC/PVA composite films, with the 0.25% formulation exhibiting the highest tensile strength of up to 26.90 MPa[2].
Polyaminopropyl biguanide (0.125-1%) reduces the diffraction peak intensity of PEC/PVA composite films and improves their thermal stability in a concentration-dependent manner[2].
The polyaminopropyl biguanide/PEC/PVA composite films (0.125-1%) exhibit potent in vitro antibacterial activity, including 100% inhibition of Penicillium italicum at a polyaminopropyl biguanide concentration of 0.125%, and show stronger activity against Staphylococcus aureus than against Escherichia coli[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
