Yphantis method

Three experimental methods are used to evaluate the term dlnc/dr in Eq. (11.4) the Archibald method, the van Holde and Baldwin method, and the Yphantis method. All are designed to determine the molecular weight of polymers (particularly biological polymers). [Pg.251]

The method of equilibrium ultracentrifugation described by Yphantis (28) was used in these studies. A double-sector centerpiece with two 2 1/2° sectors 12 mm. in length was used with standard Schlieren optics. Apparent molecular weights, M, were determined from the equation ... [Pg.40]

Cultivation of fungi of the genus Aspergillus is carried out both in solid ( Koji ) culture and liquid (submerged) culture. The first extracellular acid carboxypeptidase from Aspergillus saitoi was discovered by Ichishima [79], Using the method of Yphantis, the extrapolated molecular mass was determined to be 139,000 as shown in Figure 16 [79],... [Pg.212]
