Preparation of antisera to group-specific antigens of avian leukosis-sarcoma viruses: an alternate approach. 1977

E J Smith

Immunization of rabbits with a pooled preparation of chromato-graphically purified avian myeloblastosis virus (AMV) group-specific (gs) antigens produced relatively large volumes of antiserum that was as broadly reactive in complement-fixation (CF) tests as antiserum produced in hamsters with tumors induced by Rous sarcoma virus. This alternate procedure should be of value for routine preparation of leukosis virus gs antiserum. Other antisera prepared against disrupted AMV had spurious reactivities that confused CF testing of embryos and tissue extracts. This artifact was attributed to the high affinity of serum albumin for AMV virions and the resultant production of antibodies when plasma-derived AMV was used as immunogen. A high-molecular-weight AMV CF antigen was also found in early fractions eluted from an agarose-gel column.

UI MeSH Term Description Entries
D007106 Immune Sera Serum that contains antibodies. It is obtained from an animal that has been immunized either by ANTIGEN injection or infection with microorganisms containing the antigen. Antisera,Immune Serums,Sera, Immune,Serums, Immune
D008722 Methods A series of steps taken in order to conduct research. Techniques,Methodological Studies,Methodological Study,Procedures,Studies, Methodological,Study, Methodological,Method,Procedure,Technique
D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation. Radioimmunoassays
D002642 Chick Embryo The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching. Embryo, Chick,Chick Embryos,Embryos, Chick
D002645 Chickens Common name for the species Gallus gallus, the domestic fowl, in the family Phasianidae, order GALLIFORMES. It is descended from the red jungle fowl of SOUTHEAST ASIA. Gallus gallus,Gallus domesticus,Gallus gallus domesticus,Chicken
D003168 Complement Fixation Tests Serologic tests based on inactivation of complement by the antigen-antibody complex (stage 1). Binding of free complement can be visualized by addition of a second antigen-antibody system such as red cells and appropriate red cell antibody (hemolysin) requiring complement for its completion (stage 2). Failure of the red cells to lyse indicates that a specific antigen-antibody reaction has taken place in stage 1. If red cells lyse, free complement is present indicating no antigen-antibody reaction occurred in stage 1.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
