  • Antibacterial efficacy of copper-based metal-organic frameworks against Escherichia coli and Lactobacillus.: Agarose has been used to perform agarose gel electrophoresis for the synthesis of copper-based metal-organic frameworks, enhancing the antimicrobial properties of these compounds. This application points to the expanding role of agarose in antimicrobial research, relevant for both clinical and agricultural settings (Elmehrath et al., 2024).

Analysis Note

The following is a list of properties associated with our agaroses:
Sulfate content - used as an indicator of purity, since sulfate is the major ionic group present.
Gel strength - the force that must be applied to a gel to cause it to fracture.
Gel point - the temperature at which an aqueous agarose solution forms a gel as it cools. Agarose solutions exhibit hysteresis in the liquid-to-gel transition - that is, their gel point is not the same as their melting temperature.
Electroendosmosis (EEO) - a movement of liquid through the gel. Anionic groups in an agarose gel are affixed to the matrix and cannot move, but dissociable counter cations can migrate toward the cathode in the matrix, giving rise to EEO. Since electrophoretic movement of biopolymers is usually toward the anode, EEO can disrupt separations because of internal convection.
