Berson, SA (English spelling)

Japanese: Berson，S.A.（英語表記）BersonSA

...A well-type scintillation detector is mainly used to measure these samples, which increases the efficiency of measuring samples in test tubes. In vitro testing methods are characterized by their ability to measure extremely small amounts of substances in the body, which was impossible to do with conventional chemical or biological methods. They originated in 1959 with the radioimmunoassay (RIA) method for measuring insulin in the blood by S.A. Berson and R. Yallow. Since then, many other methods have been developed and are used in endocrinology, viral disease, and cancer-related tests.

From [Radioimmunoassay]

...In 1960, Yalow and Berson developed a method for measuring plasma insulin levels using immunoassay. It is also called radioimmunoassay.

…この試料の測定には，主としてウェル型(井戸型)シンチレーション検出器が用いられ，試験管内試料の測定効率を高めている。in vitro検査法は，従来の化学定量法や生物学的測定法などでは不可能であった生体内物質のごく微量の定量が行えるという点に特徴があり，1959年バーソンS.A.Berson，ヤローR.Yallowによる血中インシュリンの放射線免疫学的測定法(ラジオイムノアッセー，RIAと略称)に端を発している。その後多くの測定法が開発され，内分泌学やウイルス性疾患，癌関連の検査に応用されている。…
