"The item of $7,500 for apparatus, supplies, animals would permit us to use the large number of animals required for some
of our projected researches, and should permit also the construction of a Tiselius apparatus for the electrophoretic separation
of antibody fractions by the suggested method of combination with charged haptens, and for other investigations."
Linus Pauling. Letter to Warren Weaver. January 2, 1941.
