公知のHbA1c免疫測定キットに含まれる未感作ラテックス試薬(以下R1試薬)及び抗HbA1c抗体液(以下R2試薬)をそれぞれ10mLチューブに約5mL分注した。チューブを−20℃の冷凍庫で一夜保存し、R1試薬及びR2試薬を凍結させた。これらを室温に放置して解凍し、試薬の状態を目視で確認した。
R1試薬にベタイン(トリメチルグリシン)を3w/v%〜10w/v%の範囲で1%刻みに加えて、凍結・解凍の影響を調べた。各濃度のベタインを加えたR1試薬を3等分し、1本を4℃に保存した。他の2本を、検討1同様に一晩−20℃の冷凍庫に保存し、翌日室温放置により解凍した。ラテックスが凝集沈殿しているものは無かったが、チューブの底部に白色のラテックス濃度が高くなっていたので、軽く転倒混和した。2本のうちの1本を4℃に保存し、残りの1本を一晩−20℃に保存した。翌日、室温で解凍し、軽く転倒混和した。
検討2の結果より、R1試薬に加えるベタインの濃度は6w/v%付近が適当であると考えられた。そこで、ベタインを6w/v%又は7w/v%添加したR1試薬を調製し、各7本に分割し、1本を4℃に保存し、残り6本を−20℃に一晩保存した。翌日に全ての本数を取り出し、室温で解凍させ、軽く転倒混和し、1本を4℃に移し、残りを−20℃に一晩保存した。これを繰り返し、凍結・解凍の回数が0回から6回までのR1試薬を準備した。これらのR1試薬とR2試薬を日立7170自動分析機にセットし、検量線を描かせた。
公知のHbA1c免疫測定キットに含まれる未感作ラテックス試薬同等品(R1試薬)にベタインを5%から25%になるように添加した。ベタイン添加によりラテックス濃度が低下するので、ラテックス原液を加えて調整した。このベタイン添加未感作ラテックス試薬の一部を−20℃に2晩放置した後、室温に放置して解凍した。この解凍後、転倒混和したR1試薬と、冷蔵保存したR1試薬を並べて、日立7170自動分析機にセットして検量線を描かせた。なお、抗HbA1c抗体液(R2試薬)は、増感剤の量を少し増やしたものを使用した。
ベタインの代わりに、ラテックス試薬R1に界面活性剤であるTween 20を0.1v/v%添加したものを調製した。界面活性剤入りのR1試薬をチューブに採り、これを−20℃に一晩保存し、翌日、室温で解凍した。目視で観察すると、ラテックスの凝集沈殿は認められなかった。そこで、界面活性剤入りのR1試薬を用いて、日立7170で検量線を描かせた。その結果を検討3の結果とあわせて図2に示す。反応性が全く無かったことから、界面活性剤によりHbA1cのラテックス表面への物理吸着が妨げられたことは明白である。
