    摘要: An IgE-binding protein, .epsilon.BP, which contains two domains: the amino-terminal domain (140 amino acids) consists of a highly conserved repetitive amino acid sequence, Tyr-Pro-Gly-Pro/Gln-Ala/Thr-Pro-Ala-Pro-Gly-Ala, whereas the carboxyl-terminal domain (122 amino acids) shares significant sequence homology with a domain of lymphocyte/macrophage receptor for the Fc portion of IgG is disclosed.

    摘要: In accordance with the present invention, there are provided methods for the separation of biological materials employing a variety of polymeric materials with defined chemical, physical and mechanical properties. Thus, a wide range of biological materials (i.e., from very low to very high molecular weight) can be separated according to the present invention. Polymeric materials contemplated for use in the practice of the present invention are block copolymers of partially hydrolyzed acrylonitrile which have excellent storage stability, are chemically inert, contain minimal residual concentration of monomeric species, and can be prepared in large scale.
