An antibody digested by papain yields three fragments, two Fab fragments and one Fc fragment An antibody digested by pepsin yields two fragments: a F(ab') 2 fragment and a pFc' fragment The fragment crystallizable region ( Fc region ) is the tail region of an antibody that interacts with cell surface receptors called Fc receptors and some ...
A general representation of the method used to produce monoclonal antibodies [1] [2] A monoclonal antibody (mAb, more rarely called moAb) is an antibody produced from a cell lineage made by cloning a unique white blood cell. All subsequent antibodies derived this way trace back to a unique parent cell.
Monoclonal antibody: a single hybridoma cell, which by chance includes the appropriate V(D)J recombination to produce the desired antibody, is cloned to produce a large population of identical cells. In informal laboratory jargon, the monoclonal antibodies isolated from cell culture supernatants of these hybridoma clones (hybridoma lines) are ...
The fragment antigen-binding region (Fab region) is a region on an antibody that binds to antigens. It is composed of one constant and one variable domain of each of the heavy and the light chain . The variable domain contains the paratope (the antigen-binding site), comprising a set of complementarity-determining regions , at the amino ...
Antibody crystallizable region (Fc) 3. Heavy chains 4. Light chains 5. Variable region of the antibody. The paratope is the key-shaped section that makes direct contact with the antigen. [1] 6. Hinge regions . In immunology, a paratope, also known as an antigen-binding site, is the part of an antibody which recognizes and binds to an antigen.
Clonality implies the state of a cell or a substance being derived from one source or the other. Thus there are terms like polyclonal—derived from many clones; oligoclonal [2] —derived from a few clones; and monoclonal—derived from one clone. These terms are most commonly used in context of antibodies or immunocytes.
Monoclonal antibodies can be acquired in the immune system via passive immunity or active immunity. The advantage of active monoclonal antibody therapy is the fact that the immune system will produce antibodies long-term, with only a short-term drug administration to induce this response.
