摘要

PROBLEM TO BE SOLVED: To provide an antibody against a novel cytokine protein called a cytotoxic lymphocyte maturation factor(CLMF) produced and synthesized by a human B-lymphoblast cell system. SOLUTION: This antibody is composed of a particular amino acid sequence (refer to the specification), has at least 5.2×107 unit/mg of specific activity, and is an essencially pure polyclonal or monoclonal antibody to the cytotoxic lymphocyte maturation factor(CLMF) protein active by T-cell growth factor assay.
