Immunoassay and kit for insulin-like growth factors

摘要

Described are immunoassay of insulin-like growth factors in a biological sample, which comprises prior to the immunoassay, treating the biological sample with an acid solution to liberate the insulin-like growth factors from insulin-like growth factor binding proteins and then neutralizing the so-treated biological sample with a neutralizing buffer containing a recombination inhibitor; and immunoassay kit for insulin-like growth factors.
