Abstract (en)

[origin: WO8303678A1] Process for affinity purification of antigens and antibodies that employs monoclonal antibodies having a high affinity for the antigen in a first environment and a low affinity in a second environment, the environments being ones in which the immuno-chemical properties of the antigens and antibodies are not adversely affected. Also described is a process for fractionating antisera to obtain an antibody fraction having similar antigen binding properties as exhibited by the environmentally sensitive monoclonal antibodies. The effect of varying pH in the binding capability of tow monoclonal antibodies for human growth hormone is shown in fig. 1.
