    Tetra-N-acetyl-chitotetraose, penta-N-acetylchitopentaose and hexa-N-acetyl-chitohexaose, ones of the water-soluble chitin-oligomers, may be obtained in improved yields, when finely ground chitin is quickly and intimately mixed with a concentrated hydrohalogenic acid containing a particular proportion of the hydrogen halide per a unit quantity of the chitin under the irradiation with ultrasonic waves and also under the agitation by mechanical stirrer, followed by hydrolyzing the chitin in the resulting homogeneous mixture comprising the chitin and the concentrated hydrohalogenic acid while said homogeneous mixture is further continuously irradiated with the ultrasonic waves and also agitated by the mechanical stirrer. From the aqueous phase of the hydrolyzed reaction mixture are recovered the desired water-soluble chitin-oligomers which are each useful as an immunopotentiating, antitumor agent or antifungal, antibacterial agent.

    This invention provides a method of altering the affinity of an antibody for the antigen to which it is directed which comprises introducing into the variable region of the antibody a carbohydrate recognition site under conditions such that a carbohydrate binds to the site and thus attaches to the antibody. This invention also provides a method of modifying the carbohydrate content of an antibody which comprises deleting from a constant region of the antibody a carbohydrate recognition site which naturally occurs in such constant region of such antibody. Antibodies, e.g., monoclonal antibodies and human monoclonal antibodies, diagnostic test kits, DNA encoding antibodies, therapeutic agents, and methods for detecting the presence of a substance in a sample, and for recovering and purifying a substance from a sample are also provided.
    本发明提供了一种改变抗体对其所针对的抗原的亲和力的方法,该方法包括在抗体的可变区中引入一个碳水化合物识别位点,使碳水化合物与该位点结合,从而附着在抗体上。本发明还提供了一种改变抗体中碳水化合物含量的方法,该方法包括从抗体的恒定区中删除自然存在于该抗体恒定区中的碳水化合物识别位点。本发明还提供了抗体,例如单克隆抗体和人类单克隆抗体、诊断测试试剂盒、编码抗体的 DNA、治疗剂,以及检测样品中是否存在某种物质和从样品中回收和纯化某种物质的方法。
