    This gel is one of our Optiblot precast gels which offer superior rigidity and stability over traditional polyacrlyamide gels and are compatible with the most common tanks and systems. For convenience the precast gels come with the comb already removed as the cassette locks the fingers in place; for additional convenience there is no tape to be removed and cassettes can be opened by hand.

    Optiblot gels must be used with Optiblot buffers.
