タンパク質供給源
全長組換えラット受容体を大腸菌(E. coli)BL21(DE3) Codon Plus RIL細胞中で発現させ、2つの異なるカラムクロマトグラフィー系を用いて均質に精製した。第一の系は、このタンパク質のC末端ヒスチジンタグを用いるニッケルアフィニティ樹脂であった。この樹脂から溶出したタンパク質を、イオン交換クロマトグラフィー(S-Sepharose Fast Flow)を用いてさらに精製した。精製したタンパク質のアリコートを液体窒素中で急速凍結し、使用時まで-80℃で保存した。結合アッセイで用いるために、タンパク質を、0.1%Chaps界面活性剤を含むTEDK50(50mMトリス、1.5mM EDTA、pH7.4、5mM DTT、150mM KCl)で希釈した。受容体タンパク質およびリガンド濃度を、加えた放射性標識リガンドの20%以下が受容体に結合するように最適化した。
非標識リガンドをエタノールに溶解し、UV分光光度法を用いて濃度を定量した(1,25(OH)2D3:モル吸光係数=18,200およびλmax=265nm;類縁体:モル吸光係数=42,000およびλmax=252nm)。放射性標識リガンド(3H-1,25(OH)2D3、約159Ci/mmol)は、最終濃度1nMでエタノール中に加えた。
放射性標識および非標識リガンドを希釈タンパク質100mclに最終エタノール濃度≦10%で加え、混合し、氷上で一晩インキュベーションして結合平衡に到達させた。翌日、ヒドロキシルアパタイトスラリー(50%)(100mcl)を各チューブに加え、10分間隔で30分間混合した。ヒドロキシルアパタイトを遠沈により回収し、次いで0.5%Triton X-100を含むトリス-EDTA緩衝液(50mMトリス、1.5mM EDTA、pH7.4)で3回洗浄した。最終洗浄後、ペレットを、Biosafe IIシンチレーションカクテル4mLを含むシンチレーションバイアルに移し、混合し、シンチレーション計数器に置いた。全結合を、放射性標識リガンドのみを含むチューブから定量した。

雄の離乳Sprague-Dawleyラットを、Diet 11(0.47%Ca)飼料+AEKで1週間、続いてDiet 11(0.02%Ca)+AEKで3週間飼育した。次いでラットを、0.47%Caを含む飼料で1週間、続いて0.02%Caを含む飼料で2週間へと切り換えた。用量投与を0.02%カルシウム飼料の最終週の間に開始した。4回の連続したip投与を約24時間おきに行った。最後の投与から24時間後、切断頸部から採血し、血清カルシウム濃度を骨カルシウム動員の尺度として定量した。反転腸管法(everted gut sac method)を用いた腸管カルシウム輸送アッセイのために腸の起始部10cmも採取した。反転腸管アッセイは、Martin and Deluca, Am. J. Physiol. 216, 1351 (1969); (DeLuca et al., 米国特許第4,188,345号)により以前に記載されたように実施したが、これらは、その全文が本明細書に記載されたのと同じように参照により組み入れられる。Perkin Elmer Model 3110を用いる原子吸光アッセイにより、および血清を0.1%塩化ランタンで希釈することにより、血清カルシウムを定量した。
