Monoclonal Antibodies (mAb): Harvesting, Types, Applications
Monoclonal antibodies (mAb) are defined as the antibodies derived from a single clone of plasma cell, all having the same antigen specificity, i.e. produced against a single epitope of an...
Common antigens (or antigens of similar nature) that are possessed by a variety of phylogenetically unrelated species are known as heterophile antigens. Antibodies induced by these antigens...
Coombs test (antiglobulin test) is used to detect the presence of ‘incomplete’ Rh antibodies i.e. IgG antibodies capable of sensitizing RBCs but incapable of causing agglutination of RBCs...
