Some precipitin tests and preliminary remarks on the systematic relationships of four South American families of frogs.
Graphs of precipitin reactions illustrating effects of formalin on antigenicity and reactivity of the extracts.
The antiserum used for the precipitin reaction was obtained by treating a rabbit with human blood serum.
The method of precipitin testing follows that outlined by Leone .
Sasaki demonstrated the usefulness of the precipitin technique in distinguishing species of ducks and their hybrids.
Now all these specific reactions, the precipitin reaction as well as the anaphylactic reaction, can be called forth by proteins.
The precipitin reaction, however, has never been applied to actual problems in avian taxonomy prior to the present study.
The precipitin reaction is the most successful of the serological techniques thus far devised for systematic comparisons.
Plots representative of the precipitin curves are presented in Figs. 10 to 21.
