Agarose, LF™ for pulsed field gel electrophoresis (PFGE)
Supplier: VWR Chemicals
Agarose LF™ (Large Fragment, 1 kb - 40 kb) is optimised for pulsed-field gel electrophoresis (PFGE) applications. The exceptionally low EEO (electroendosmosis) and high gel strength of Agarose LF™ facilitates faster electrophoresis running times in low concentration gels. This agarose is best suited for resolving large (>20 kb) DNA fragments.
