TESTING ANTITOXIN ON GUINEA PIGS
COPYRIGHT,
PHILADELPHIA
Mulford's Antitoxin IS PREPARED
personally by skilled bacteriologists, in accordance with
the most rigid requirements of science. Surgical germfree
cleanliness characterizes every step of its production; the
exact unit strengths of toxins and antitoxins are deter-
mined with absolute mathematical precision; the
harmlessness of each separate yield of antitoxin is
established by repeated series of tests on guinea pigs;
the antitoxin never comes in even momentary con-
tact with the atmosphere. The preparation of
Mulford's Antitoxin is so completely surrounded
with safeguards that contamination can never
occur.
Especially to be emphasized is the elaborate
system of testing the antitoxin for strength and
purity. At least fifty guinea pigs are required to
determine the purity, unit strength and non-
irritating character of each separate yield of
antitoxin.
Since 1894 many millions of tubes of Mulford's
Antitoxin have been employed without a single un-
toward result of any kind. All reports prove that it
saves more lives than all other serums combined.
