• Low-melting point agarose as embedding medium for MALDI mass spectrometry imaging and laser-capture microdissection-based proteomics.: Demonstrates the use of low-melting point agarose as a versatile medium for advanced imaging and proteomic analysis, contributing significantly to analytical biochemistry (McDonnell et al., 2023).


• Autocrine regulation of tumor cell repopulation by Hsp70-HMGB1 alarmin complex.: Agarose is utilized in the study of cellular mechanisms for cancer research, underscoring its importance in experimental setups requiring precise biological simulations (Guzhova et al., 2023).

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.
