Abstract
|
|
|
|
Progesterone immunogen has been synthesized and its melting point, Rf-value, UV and IR spectrum have been measured to develope the essential step in antisera production against low molecular weight substance. Mixed anhydride reaction was used to conjugate 11α-hydroxy-progesterone with succinic anhydride. Melting point of one intermediate compound was 156℃, and Rf-value was 0.41 in benzene : acetone : methanol (5 : 5 : 2). Maximum absorbance was measured at 242nm and εwas 1.641×10⁴㎝²/mo1e. Loss of hydroxy group was observed at 3450nm, and carbonyl group was appeared at 1160nm, 1250nm and 2960nm. These results indicated that the intermediate compound was progesterone hemisuccinate. Maximum absorbance of progesterone bovine-serum albumin(BSA) conjugate was observed at 250nm. Molar ratio of progesterone to BSA was average 15.4 on UV spectrum.
