Abstract
Description
難溶性抗原である大腸菌で発現させたリコンビナントシスタチンC((株)免疫生物研究所)10mgと、分散安定化剤としてのポリビニルピロリドン50mg、界面活性剤としてのポリオキシル20セチルエーテル100mgとを試験管にとり、ジメチルスルフオキシド(DMSO)2mLに溶解した。減圧条件下でDMSO溶液を乾固し、抗原と分散安定化剤が均一に分子分散した残存物(以下、「ペレット」という)を得た。得られたペレットに水1.0mLを添加し、密閉した。
シスタチンC微粒子分散液を用いて得られたウサギ抗血清(No.4〜6)、及び、未処理のシスタチンCを用いて得られたウサギ抗血清(No.1〜3)、及び、変性剤を添加したシスタチンC溶液を用いて作製された市販のウサギ抗シスタチンC抗血清(ダコ・ジャンパン株式会社)(No.7)について、ELISA法による力価の測定を行った。
実施例2と同じ抗体を用いて、Inhibition法により抗原特異性の評価を行った。尿由来ヒトシスタチンCを4000〜7.8ng/mLまで2倍連続希釈した抗原液、及び抗原の含まれていない溶液を、先の力価測定の結果から力価を揃えた各抗血清と等量混合して、37℃で60分静置した(一次反応)。次いで一次反応した溶液を、尿由来ヒトシスタチンCを50ng/ウェルでコートしたタイタープレートに添加し、37℃で60分反応させた。その後、ペルオキシダーゼ標識ヤギ抗ウサギIgG抗体を添加し、オルソフェニレンジアミン発色による490nmの吸光度を測定した。抗原が含まれていない溶液で測定した吸光度を100%として、各抗原濃度での割合を算出した。ウサギを4回免疫後の抗血清の吸光度の結果は表3、ウサギを6回免疫後の抗血清の吸光度の結果を表4に示した。
