SURVIVAL OF VACCINE VIRUS SEPARATED FROM LIVING HOST CELLS BY COLLODION MEMBRANES.
Vaccine virus, suspended in a mixture of serum and Tyrode's solution and separated by collodion membranes from a suspension of living kidney cells in serum and Tyrode's solution, remained active at 37 degrees C. for a longer period of time than did vaccine virus incubated only in a mixture of serum and Tyrode solution.
