I confess! Sometime in my past I managed to ignite a Southern blot on
nitrocellulose. It did not explode. It burned rapidly, but not
instantaneously with a cool yellow flame. The burning could be retarded
but not suffocated by blanketing the NC with 3MM paper. The filter paper
did not catch fire either, and I could not feel any heat through the
filter paper. All I lost was a valuable Southern blot and three years
