CA-125 was initially detected using the murine monoclonal antibody designated OC125. Robert Bast, Robert Knapp and their research team first isolated this monoclonal antibody in 1981. [28] The protein was named "cancer antigen 125" because OC125 was the 125th antibody produced against the ovarian cancer cell line that was being studied. [29]
Sofituzumab vedotin (INN; [1] development code DMUC5754A) is a monoclonal antibody designed for the treatment of ovarian cancer. [2] This drug was developed by Genentech/Roche. Sofituzumab vedotin is an antibody-drug conjugate that targets MUC16, a protein that is overexpressed in several types of cancer including ovarian and pancreatic cancer ...
This radiolabeled antigen is then mixed with a known amount of antibody for that antigen, and as a result, the two specifically bind to one another. Then, a sample of serum from a patient containing an unknown quantity of that same antigen is added. This causes the unlabeled (or "cold") antigen from the serum to compete with the radiolabeled ...
Types of monoclonal antibodies with other structures than naturally occurring antibodies. The abbreviations in the column Type are as follows: mab: whole monoclonal antibody; Fab: fragment, antigen-binding (one arm) F(ab') 2: fragment, antigen-binding, including hinge region (both arms) Fab': fragment, antigen-binding, including hinge region ...
Immunofluorescence pattern of SS-A and SS-B antibodies. Produced using serum from a patient on HEp-20-10 cells with a FITC conjugate. Anti-SSA autoantibodies (anti–Sjögren's-syndrome-related antigen A autoantibodies, also called anti-Ro, or similar names including anti-SSA/Ro, anti-Ro/SSA, anti–SS-A/Ro, and anti-Ro/SS-A) are a type of anti-nuclear autoantibodies that are associated with ...
In immunology, antibodies (immunoglobulins (Ig)) are classified into several types called isotypes or classes.The variable (V) regions near the tip of the antibody can differ from molecule to molecule in countless ways, allowing it to specifically target an antigen (or more exactly, an epitope).
Each antibody binds to a specific antigen in a highly specific interaction analogous to a lock and key.. An antibody (Ab) or immunoglobulin (Ig) is a large, Y-shaped protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as bacteria and viruses, including those that cause disease.
The antibody has a three-dimensional structure with beta pleated sheet and alpha helices. [5] The antibody folds so the variable regions form three loops with the framework regions folded into one another and the CDR regions on the tips of each of these loops in direct contact with the antigen.
