title: The properties of Corbicula sandai apoferritin.
abstract: Corbicula sandai apoferritin possesses physical properties different from apoferritins of other species. The native molecular weight was estimated from its s020,w of 18.7 S to be about 503 000. Empirical molecular weight estimation methods in denaturing solvents yielded a molecular weight estimate for the constituent polypeptide chain of 23 000. The circular dichroic spectrum of C. sandai apoferritin was significantly different from other apoferritins and it was immunologically unreactive with rabbit anti-human ferritin antisera.
