Abstract:
An improved process for reducing the divalent metal ion content to less than 10 7 M concentration of a solution of orgotein containing greater than 10 7 M concentration of a divalent metal having an ionic radius from 0.65 to 0.79 A, which comprises reducing the ion content to less than 10 7 M by passing the buffer solution having an ion content greater than 10 7 M through an ion exchange resin bed consisting of a single ion exchange resin having both acidic and basic groups which are in sufficiently close proximity so that the resin is partially neutralized internally yet sufficiently separated spatially so that the resin has absorptive attraction for both anions and cations.
Abstract:
ORGOTEIN IS ISOLATED FROM LYSED PLASMA-FREE ERYTHROCYTES BY A SERIES OF STEPS WHICH INCLUDE REMOVING THE HEMOGLOBIN FROM THE LYSATE, HEATING THE REMANING SOLUBLE PROTEINS IN THE PRESENCE OF BUFFER AND DIVALENT METAL ION UNTIL THE CARBONIC ANHYDRASE IS INACTIVATED, REMOVING THE PRECIPITATE, AND SEPARATING THE ORGOTEIN PROTEIN FROM THE SUPERNATANT LIQUID.
Abstract:
SUCROSE, GLUCOSE, MANNOSE, AND CERTAIN PENTOSE HEXOSE AND HEPTOSE SACCHARIDES IMPROVE THE SABILITY OF ORGOTEIN TO LYOPHILIZATION AND STORAGE. ORGOTEIN IS THE NAME ASSIGNED BY USCAN TO AN ISOLATED, SUBSTANITIALLY PURE, SOLUBLE, GLOBULAR, NON-TOXIC AND SUBSTANTIALLY NON-ANTIGENIC METALLOPROTEIN HAVING ANTI-INFLAMMATORY AND OTHER PHARMACODYNAMIC ACTIVITY.
Abstract:
THE PAIN AND STRUCTURAL ABNORMALITIES ASSOCIATED WITH POST-TRAUMATIC ARTHRITIS ARE ALLEVIATED BY SYSTEMIC ADMINISTRATION OF ORGOTEIN TO THE PATIENT AFFECTED WITH THE ARTHRITIC CONDITION.
Abstract:
Heat labile tenacious proteins present in samples of substantially pure orgotein produced by a process which comprises a heating step in which a mixture of proteins comprising the orgotein protein and substantial amounts of other proteins are heated under conditions which do not affect the orgotein, are eliminated therefrom by a second heating step of a solution of the substantially pure orgotein in a buffer containing divalent metal ions at a temperature higher than employed in the prior heating step.
