Abstract

Antigen-binding fragments (Fab) of mouse monoclonal antibodies to human interleukin-2 were obtained in preparative quantities by a modified procedure. These Fab-fragments were shown to be homogeneous according to the isoelectric focusing method. Various monocrystals of these free Fab-fragments and their complexes with the antigenic peptide corresponding to the 59-72 sequence of interleukin-2 were obtained. These were shown to be suitable for X-ray and were preliminarily studied by X-ray.
