Agarose IV is a linear polymer with a very high molecular weight, giving gel structures unlike those of traditional agaroses. This characteristic produces a strong intercatenary interaction, yeilding a gel with very high gel strength and higher exclusion limit.
For improved resolution, we recommend storing the gel at 4°C for 30 minutes before use.

Migration in the TBE Buffer is slower, therefore lower concentrations can be used to obtain similar separation ranges.
Applications:
- Conventional Electrophoresis
- Pulsed Field Gel Electrophoresis: Due to its higher exclusion limit, large molecules can be separated
- Blotting
- Agarose Bead Preparation
- Cell and Enzyme Immobilization
