The antibody recognizes a unique molecule of the pathogen, called an antigen . (wikipedia.org)
[2] [3] Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (analogous to a key) on an antigen, allowing these two structures to bind together with precision. (wikipedia.org)
To allow the immune system to recognize millions of different antigens, the antigen-binding sites at both tips of the antibody come in an equally wide variety. (wikipedia.org)
The class hence determines the function triggered by an antibody after binding to an antigen, in addition to some structural features. (wikipedia.org)
After an antigen binds to a BCR, the B cell activates to proliferate and differentiate into either plasma cells , which secrete soluble antibodies with the same paratope, or memory B cells , which survive in the body to enable long-lasting immunity to the antigen. (wikipedia.org)

Pretreatment of the cells with the anti-CD45 mAb M1/89.18.7.HK markedly inhibited all three biological responses, while an alternate anti-CD45 antibody, M1/9.3.4.HL.2, had little effect. (mssm.edu)
The two antibodies bound to CD45 with similar affinities, and no differences in the lateral mobility of antibody-CD45 complexes in the cell membrane were observed. (mssm.edu)
If M1/89.18.7.HK was added to the 13.13 cells after they had already been activated with anti-CD3, it very effectively stimulated dephosphorylation of substrates that had been phosphorylated on tyrosines prior to adding the anti-CD45 antibody. (mssm.edu)
These results indicate that the phosphotyrosine protein phosphatase activity of CD45 is critical to its biological function and that bivalent (i.e. uncross-linked) anti-CD45 antibodies can give rise to markedly different responses. (mssm.edu)
One of the antibodies, M1/89.18.7.HK, appears to behave much like a receptor ligand and is able to activate the enzymatic activity associated with the CD45 transmembrane protein. (mssm.edu)
