title: COMPLEMENT: INACTIVATION OF SECOND COMPONENT BY P-HYDROXYMERCURIBENZOATE.
abstract: p-Hydroxymercuribenzoate inactivates the second component of complement whether it is in solution or is fixed to a sensitized erythrocyte together with the first and fourth components. Inactivation by the drug is blocked but not reversed by cysteine. Partial purification of the second component of complement is described.
