Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
89 words
A COMPOSITION OF MATTER COMPRISING A POWDERED PRODUCT, SAID PRODUCT BEING A PRODUCT OF REACTION OF BLOOD PROTEIN AND GLUTARADEHYDE AND CONTAINING AN AMOUNT OF GLUTARALDEHYDE CONSTIUTING BETWEEN 0.1% AND 2.4% BASED UPON THE WEIGHT OF BLOOD SOLIDS, SAID PRODUCT BEING SUBSTANTIALLY INSOLUBLE IN WATER AND HAVING A MAJOR PORTION OF THE PRODUCT SOLUBLE IN AN ALKALINE SOLUTION WHICH IS A 2.5% SOLIDS CONTENT DISPERSION OF SAID PRODUCT IN WATER CONTAINING 0.1 GRAM OF SODIUM HYDROXIDE PER GRAM OF SAID PRODUCT MAINTAINED AT 70*F. AND AGITATED FOR 10 MINUTES.
Claim 2
Dependent Claim
89 words
A COMPOSITION OF MATTER COMPRISING A POWDERED PRODUCT, SAID PRODUCT BEING A PRODUCT OF REACTION OF BLOOD PROTEIN AND GLUTARADEHYDE AND CONTAINING AN AMOUNT OF GLUTARALDEHYDE CONSTIUTING BETWEEN 0.1% AND 2.4% BASED UPON THE WEIGHT OF BLOOD SOLIDS, SAID PRODUCT BEING SUBSTANTIALLY INSOLUBLE IN WATER AND HAVING A MAJOR PORTION OF THE PRODUCT SOLUBLE IN AN ALKALINE SOLUTION WHICH IS A 2.5% SOLIDS CONTENT DISPERSION OF SAID PRODUCT IN WATER CONTAINING 0.1 GRAM OF SODIUM HYDROXIDE PER GRAM OF SAID PRODUCT MAINTAINED AT 70*F.
