Recent studies show that immunoglobulins A, G, and M contribute significantly to the maintenance of udder health. Unfortunately, the concentration of immunoglobulins in cow milk during the middle period of lactation is low therefore the question of how to stimulate and maintain a sufficient level and spectrum of antibodies in the udder is topical. The aim of the present study was to evaluate th...

The distribution of maternal immunoglobulins in the mouse uterus and embryo in the days after implantation has been studied on sections incubated with sheep Fab anti-mouse immunoglobulins labeled with peroxidase. At the time of implantation the blastocyst is already surrounded by immunoglobulins that are also present in the blastocoel and early endoderm; uterine glands contain large amounts of ...

Blood samples obtained 24 and 36 hr postparturition from 187 calves in 2 years were analyzed for serum concentration of immunoglobulins G1 (IgG1) and M (IgM). Serum and colostrum samples also were obtained from their dams, and corresponding immunoglobulin levels were determined. Calves were evaluated for their ability to acquire and absorb immunoglobulins and cows for their ability to produce i...

1. This study presents an easy protocol to measure the amount of immunoglobulins from the blood serum of different bird species in the wild ( Ficedula hypoleuca Pallas, Parus caeruleus L., Lanius meridionalis Temminkck, Lanius collurio L., Athene noctua Scopoli and Falco tinnunculus L.) by direct enzyme-linked immunosorbent assay, ELISA using commercial antichicken antibodies. 2. Additionally, ...

-The three known classes of immunoglobulins from Minnesota miniature swine have been isolated from sow serum. Whole immunoglobulin molecules and their constituent chains have been characterized physically, and monospecific anti-chain sera have been prepared to ?-chains, /z-chains, a-chains and light chains. The average concentration of each immunoglobulin class in sow serum has also been determ...

It was supposed that lung and breast cancer risks significantly increased when the levels of serum immunoglobulins A antibodies against benzo[a]pyrene and estradiol increased together, but did not separately. However, the cancer risks dramatically decreased when the levels of immunoglobulins A against progesterone elevated separately or together with immunoglobulins A against benzo[a]pyrene and...

Beta-2A globulin and the 7S and 19S gamma globulins are the major proteins of the serum derived from the immune system. Collectively they have been termed the immunoglobulins. The 19S gamma globulin, also known as the gamma-1 macroglobulin, the 82 macroglobulin or 82M, has been the subject of intensive study in recent years. The rheumatoid factor as well as a variety of anti-bodies fall into th...
