[First domestic production of transaminase assay reagents].
Ultraviolet absorption has continued to improve and has become a commonly used method. The development of automated instruments has also contributed to its use, making the Reitman-Frankel Method retire from the prominent stage it once occupied. While the Camen Method was indicated to be short of substrates, it is now used after incorporating improvements proposed from various countries, including the JSCC recommendation from Japan, as a titration method for the enzyme reference materials. The JSCC Common Standards Method was further provisioned through detailed examinations ot its reagents and processes, and is utilized under strict conditions. Standardization has thus evolved from more technique to what includes reference materials.
