Globulins, serum antibodies

In all cases, the tubes were allowed to stand for 1 hour at room temperature, following which iodinated APS-314d (4000 cpm) was added in 0.05 ml of assay buffer to all tubes, as well as to 3 tubes labeled as total radioactivity . With the exception of the latter, the tubes were vortexed for a few seconds and then they received 0.05 ml of a mixture containing anti-beraprost serum (1 50,000 dilution) sheep anti-rabbit y-globulins (200 pl/ml) and rabbit y-globuhns (200 ig/ml) (the quantity of rabbit y globulins involved depends on the quality of the purihed sheep anti-rabbit y-globulins serum and must be checked with each preparation of this second antibody). 

This situation is similar to that observed in saliva, where the passage of serum antibodies into the salivary secretion has been demonstrated (E5). When antibodies were present in serum of some healthy subjects, antibodies to various bacteria in saliva were found with hemagglutination and bacterial agglutination tests. The presence of these antibodies in saliva may be correlated with the finding of y-globulin in this secretion (E5).

Since antibodies occur in the globulin fraction of serum one predicts that the investigation of the fine structure of serum mucoproteins will become a problem of urgent immunological significance. It is doubtful however whether the carbohydrate group of mucoproteins can influence their immunological specificity.1 ...

Normal immunoglobulins (often termed immune globulins in the USA) represent antibody preparations purified from the plasma, serum or placentas of normal, healthy donors. Blood obtained from such individuals will contain a wide range of antibody specificities. The range of specificities were produced over many years, as the individual s immune system came into contact with various antigens, either naturally (infections) or artificially (by vaccination). 

Injected forms of antibodies which have been generated in another body or animal can be isolated, purified, and administered as standard human immune serum globulin (ISG), and ISG plus preparation, or as an animal antiserum or antitoxin. Some serums which are available are those for rabies, snake and insect bites, botulism, and tetanus. Temporary immunity of up to six months to hepatitis can be imparted by one "gamma globulin" shot. More permanent active immunity is available to health care workers.
