title: An exponential gradient marker for use with minigel polyacrylamide electrophoresis systems.
abstract: Minigel electrophoresis has reduced the required sample size and cost of running polyacrylamide gels without loss of resolution. The many problems incurred in the minigel system when pouring multiple gradient gels are eliminated by pouring individual gels with the described economical, exponential gradient marker, which can accurately deal with the small gel volumes. The advantages of exponential gradients are discussed.
