  • Patent number: 5185161
    Abstract: There is disclosed, in one aspect, chlorous acid generating compositions useful for disinfecting substrates. The compositions comprise aqueous solutions containing a suitable amount of a protic acid, such as citric or malic acid, and a suitable amount of a metal chlorite, such as sodium chlorite. The chlorite ion concentration which is in the form of chlorous acid in the composition is no more than about 15 percent by weight of the total amount of chlorite ion concentration. In a preferred embodiment, the composition also contains a vicinal dihydroxy or polyhydroxy compound. In another preferred embodiment, the composition contains at least a 10-fold molar excess of a water soluble chloride ion compared to the total concentration of chlorite ion. In another aspect, there is disclosed a process for disinfecting substrates. This process comprises applying the compositions described above to a substrate. In yet another aspect, there is disclosed a process for preparing the compositions described above.

  • Patent number: 4146603
    Abstract: A new class of glycoproteins has been found to be produced by human cancer cells and is not produced by normal cells and said glycoprotein is present in the sera of cancer patients. This tumor specific glycoprotein can be characterized by its isoelectric point of from about 4.2 to 4.6 and by the perchloric acid soluble fraction thereof having a sialic acid content of above about 0.065 mg/ml of initial serum sample. The presence of a tumorigenic cancer in a patient can be determined by detecting the presence of the tumor specific glycoprotein in the blood sera of a patient.
