TOTAL PROTEIN PATTERNS IN SERA OF PREGNANT WOMEN AND PLACENTAL TISSUES OF DIFFERENT GESTATIONAL AGES

Total protein patterns in sera obtained from women in different stages of gestation were studied by polyacrylamide disc gel electrophoresis. The samples showed a wide variation in number, intensity and mobility of bands.

Placental tissue collected after Medical Termination of Pregnancy (MTP) from a local hospital in Calcutta were homogenised and total protein patterns were similarly analysed following polyacrylamide disc gel electrophoresis. All samples of early pregnancy showed slight variation in the number, intensity and mobility of bands. A discrete band in the haptoglobin zone was noted in most cases.
