Extrinsic Cotton effects characteristic of specific hapten-antibody interactions.
The reversible binding of the haptens 2,4-dinitrophenyllysine (DNP-lysine) and 2,4,6-trinitrophenyllysine (TNP-lysine) to either the nitrophenyl-binding myeloma protein MOPC-315 or to pooled mouse anti-DNP or anti-TNP antibodies produces large and characteristic extrinsic Cotton effects (in the circular dichroic spectra). Despite the similarities in binding characteristics of the three proteins...
متن کاملExtrinsic Cotton effects in hapten--carrier and hapten--antibody interactions.
Two homogeneous univalent hapten-protein conjugates, prepared by the covalent attachment of a single 2,4-dinitrophenyl (DNP-) or 2,4,6-trinitrophenyl (TNP-) side chain to the cysteine-SH in the active site of the enzyme papain, have been found to exhibit large Cotton effects in the wavelength region of the absorption bands of the DNP or TNP groups. This indicates that the DNP or TNP groups are ...
متن کاملHAPTEN-SPECIFIC IgE ANTIBODY RESPONSES IN MICE
The present studies have established conditions for the demonstration of cooperative interactions between specific T and B lymphocyte populations in the development of IgE antibody responses in vivo in mice. This has been accomplished by utilizing a system which permits the successful adoptive transfer to irradiated recipients of DNP-specific secondary IgE responses with spleen cells from suita...
متن کاملOptical spectroscopy in studies of antibody-hapten interactions.
This article describes the use of optical spectroscopy in studying antibody-hapten interactions and in determining the equilibrium binding constants. Along with equilibrium binding data, spectroscopic tools often deliver structural information on binding-induced conformational changes of antibodies (or haptens). Structural implications of results from example antibody-hapten systems are include...
متن کاملElectrochemical investigation of hapten-antibody interactions by differential pulse polarography.
The binding of electroactively labeled estriol with estrogen-specific antibody and its subsequent displacement by unlabeled estriol have been monitored by differential pulse polarography. Estriol was found to be electro-inactive in the potential range -200 mV to -1000 mV vs a silver/silver chloride electrode. Estriol labeled in the 2 and 4 position with nitro groups was electroactive, giving tw...
