Pregnancy-associated leporine serum proteins: Immunochemical studies on pregnancy-associated proteins in rabbit serum.

Allotypy of Rabbit Serum Proteins

The injection into one rabbit (with Freund's adjuvants) of a specific precipitate made with antibodies from the serum of another rabbit is usually followed by the appearance in the serum of the first rabbit of antibodies which precipitate the serum of certain rabbits but not of others. It was found that the antigen (or one of the antigens) concerned in the reaction of these anti rabbit serum an...

Immunochemical Investigation of the Serum Proteins in Chick Embryos.

T H E use of specific antisera against different embryonic antigens to detect a correlation between morphological and immunochemical differentiation in ontogenesis has proved to be a valuable technique. In a study of the appearance of lens proteins in chick embryos, using various antisera and agar precipitation methods, we observed the development of precipitation lines which did not correspond...

Measurement of pregnancy-associated plasma proteins during human gestation.

Studies of four pregnancy-associated plasma proteins (PAPP's) were made on 206 plasma samples obtained from 175 pregnant women between 12 and 44 wk of gestation. The concentration of three PAPP's (A, C, and D) were assayed by quantitative crossed immunoelectrophoresis. They showed a gradual but small rate of increase during the 2nd trimester, which became more rapid in the 3rd trimester. PAPP-A...

Serum fructosamine in diabetic pregnancy.

Serum fructosamine was measured in 275 blood donors, in 559 subjects with a normal pregnancy, in 32 gestational diabetics being treated with insulin and 69 being treated by diet only, and in 53 pregnant subjects with established diabetes. In none of the pregnant subgroups did the mean fructosamine concentration exceed that of the donor group. The concentration in normal pregnant subjects showed...
