Abstract
本發明提供用於評估蛋白質藥物產品樣品之純度及鑑別該蛋白質藥物產品樣品中之雜質之MCE分析及試劑。本發明提供用於分析蛋白質藥物樣品中之分析物之方法。
Description
本發明之各態樣概言之係關於毛細管電泳之領域,特別是微晶片毛細管電泳。
實施穩健、可再現、用戶友好之技術對於滿足當今品質控制(QC)實驗室對生物產品之測試需求至關重要。技術升級係必要的,有助於提高產量,同時繼續生成高品質之分析數據,並努力儘量減少無效測試結果及儀器相關調查之數量。儘管電泳歷來用於產品純度及片段化分析之QC,但該方法已經從基於凝膠轉變為基於毛細管,最近又轉變為微晶片。微晶片毛細管電泳(MCE)可大幅縮短樣品分析時間,同時維持QC分析所需之性能及再現性標準(Ouimet,C.等人,Expert Opin Drug Discov.,12(2):213-224(2017))。
儘管MCE已經成為一種很有前途之技術,在製藥工業中越來越多地用於表徵生物製藥、品質控制及藥物發現,但其容易受到分析干擾。
因此,本發明之一個目的係提供改善之MCE分析及減少分析干擾之組合物。
本發明之另一個目的係提供用於改善蛋白質藥物產品中雜質之檢測之MCE分析及組合物。
提供用於評估蛋白質藥物產品樣品之純度及鑑別該蛋白質藥物產品樣品中之雜質之MCE分析及試劑。提供用於分析蛋白質藥物樣品中之分析物之方法。較佳蛋白質藥物包括(但不限於)抗體及其抗原結合片段、融合 蛋白及重組蛋白。該分析採用MCE技術分離、鑑別及量化蛋白質產品及蛋白質產品中之雜質。雜質包括(但不限於)蛋白質聚集體、蛋白質片段、蛋白質多聚體及分析污染物。亦提供還原及非還原緩衝液。
一個實施例提供非還原水性電泳樣品緩衝液,其含有烷基化劑,例如155至175mM 2-碘乙醯胺;0.50至1.5%十二烷基硫酸鋰;及65至95mM磷酸鈉,其中水性電泳樣品緩衝液之pH小於7。在較佳實施例中,緩衝液之pH為6。在另一個實施例中,水性緩衝液含有166mM 2-碘乙醯胺、0.81%十二烷基硫酸鋰及81mM磷酸鈉。
亦提供還原緩衝液。在一個實施例中,還原緩衝液係含有0.5至1.5%十二烷基硫酸鋰、55至85mM磷酸鈉及還原劑之水性電泳樣品緩衝液,其中水性電泳樣品緩衝液之pH大於8。在較佳實施例中,緩衝液之pH為9。在一個實施例中,還原緩衝液含有135至155mM二硫蘇糖醇。另一個實施例提供含有0.69%十二烷基硫酸鋰、69mM磷酸鈉及142mM二硫蘇糖醇之還原緩衝液。
一個實施例提供用於鑑別蛋白質藥物樣品中之污染物或雜質之非還原MCE方法,其包括將蛋白質樣品添加至上述非還原緩衝液以形成緩衝蛋白質藥物樣品之步驟。將緩衝蛋白質藥物樣品加熱至65至85℃並保持5至15分鐘,形成變性緩衝蛋白質藥物樣品。在較佳實施例中,將緩衝蛋白質藥物樣品加熱至70℃並保持10分鐘。
將蛋白質藥物樣品與可檢測之標記混合,並在30至40℃下加熱20至40分鐘,以形成變性之經標記蛋白質藥物樣品。較佳可檢測標記包括(但不限於)Dyomics DY-631 NHS酯。可以使用其他可檢測標記,包括其他染料、螢光團、發色團、質量標籤、量子點及諸如此類以及美國專利第6,924,372號中所揭示之彼等標記,該專利之全文皆以引用方式併入本文中。在較佳實施例中,將添加有標記之蛋白質藥物樣品加熱至35℃並保持30分鐘。多餘之標記視情況地從樣品去除,例如藉由使用旋轉過濾器。

溶液亦可含有能提高生長及/或存活率超過最小速率之組分,包括激素及生長因子。溶液可以配製成對於培養之特定細胞之存活及增殖最佳之pH及鹽濃度。

表1顯示用於製備MCE分析之樣品之工作流程。簡言之,將蛋白質樣品稀釋至0.5mg/ml。將1μl非還原(NR)或還原(R)變性緩衝液及4μl稀釋樣品添加至96孔板。將樣品混合、離心並在產品規定之溫度(通常為75℃)下加熱10分鐘。然後用5μM市售染料(例如Dyomics DY-631 NHS酯)標記樣品。將樣品混合,離心,然後在35℃加熱30分鐘。然後用105μl稀終止溶液稀釋標記之樣品。使用LabChip GXII或LabChip GXII觸摸HT分離樣品。
製備200mM一水合磷酸鈉、200mM二水合磷酸鈉及10%十二烷基硫酸鋰(LDS)之儲備溶液。使用儲備溶液及Milli-Q®水,製備100mM磷 酸鈉1% LDS pH 6及100mM磷酸鈉1% LDS pH 9之溶液。
藉由添加34μL 1M碘乙醯胺(IAM)(在Milli-Q®水中新鮮製備)+166μL 100mM磷酸鈉1% LDS pH 6+5μL Milli-Q®水來製備非還原緩衝液。最終濃度為166mM2-碘乙醯胺、0.81%十二烷基硫酸鋰及81mM磷酸鈉。
藉由添加68μL 10x還原劑(500mM二硫蘇糖醇(DTT)+166μL 100mM磷酸鈉1% LDS pH 9+6μL Milli-Q®水)製備還原緩衝液。最終濃度為0.69%十二烷基硫酸鋰;69mM磷酸鈉及142mM二硫蘇糖醇。
微晶片毛細管電泳(MCE)可大幅縮短樣品分析時間,同時保持QC分析所需之性能及重現性標準。使用本文所揭示之非還原及還原變性緩衝液開發MCE分析。圖1A-1B顯示代表性電泳圖,其顯示非還原樣品及還原樣品中蛋白質之分析。
雖然在前面之說明書中,已經針對本發明之某些實施例描述了本發明,並且出於說明之目的,已經提出了許多細節,但熟習此項技術者將明瞭本發明容易受到其他實施例之影響,並且在不背離本發明之基本原理之情況下,本文描述之某些細節可以有相當大之變化。
