AMSBIO offers a broad range of precast polyacrylamide gels for horizontal isoelectric focusing. The poylacrylamide layer is either bound to a sturdy support GEL-FIX,
an inert polyester film, activated to bind irreversibly to polyacrylamide, or to NetFix, an inert polyester fabric, activated to bind polyacrylamide but open to both sides
of the gel. NetFix™ is particularly useful when blotting is applied after electrophoresis as it stabilizes the gel but leaves both gel surfaces open, suitable for transfer.
The surface of each precast gel is protected with a thin cover sheet (GEL-FIX for covers) against damage and drying out. SERVA precast gels are separately packed, each individually
sealed in an Aluthen bag which adds to longevity. SERVA precast gels are ready-to-use and offered with thin and ultrathin gel layers.
