One of these molecules is chemically linked to a cytotoxic payload in an ADC, a form of targeted cancer therapy. (10[1])HAT medium is used to incubate hybridomas in a technique for producing large amounts of one type (10[1])of these molecules. These molecules’ hinge regions connect their Fab (“F-A-B”) and Fc (“F-C”) regions. (10[1])The diversity of certain receptors and these molecules is facilitated through V(D)J recombination. (10[1])A type of these proteins that only recognizes a single target is called (10[2])“monoclonal.” (-5[1])These (10[1])proteins (10[1])can class-switch (10[1])between their five isotypes and consist of two heavy chains and two light chains. (10[1])For 10 points, B cells produce what Y-shaped proteins that bind to antigens? ■END■ (10[2])

ANSWER: antibodies [or antibody; or immunoglobulins; accept monoclonal antibodies or mAbs; accept Igs; accept antibody-drug conjugates] (The receptors in the fourth line are T-cell receptors.)
