One of these molecules is chemically linked to a cytotoxic payload in an ADC, a form of targeted cancer therapy. (10[2]-5[1])HAT (10[1])medium is used to incubate hybridomas in a technique for producing large (10[1]-5[1])amounts of one type (10[2])of these molecules. (10[5])These molecules’ hinge regions connect their Fab (10[5]-5[1])(“F-A-B”) and Fc (10[4])(“F-C”) regions. (10[8])The diversity of certain receptors and these molecules (10[1]-5[1])is facilitated (10[1])through V(D)J (10[1])recombination. (10[7])A type of these proteins (10[1])that (10[1])only recognizes (10[2])a single target (10[2]-5[1])is called (10[5]-5[1])“monoclonal.” (10[8]-5[3])These (10[3])proteins (10[5]-5[1])can (10[3])class-switch (10[10])between their (10[1])five isotypes (10[2])and consist of two heavy chains (10[1])and two light chains. (10[4])For 10 (-5[1])points, B cells (10[1])produce (-5[1])what (10[1])Y-shaped (10[2])proteins (10[5])that (10[2])bind to (10[1])antigens? (10[3]0[1]-5[1])■END■ (10[17]0[6])
