リキッドハンドラーでFFPE DNAを迅速に抽出

Maxwell® HT DNA FFPE Isolation System はFFPE(ホルマリン固定、パラフィン包埋)組織サンプルからの迅速なゲノムDNAの精製を多検体で行うためのシンプルで信頼性の高い方法を提供します。精製したDNAはPCRや次世代シークエンシングなど様々なアプリケーションでそのまま使用することができます。

Maxwell® HT DNA FFPE Isolation Systemは核酸の捕捉、洗浄および溶出に最適化された移動型の固層である常磁性体粒子を用いてゲノムDNAを精製します。DNA捕捉に常磁性体粒子を使用することにより、遠心や吸引マニホールドが不要になるので、完全自動化に最適です。さらに本システムは有機溶媒も使用しないので安全で便利です。

FFPE システムのパフォーマンス比較

Maxwell® HT DNA FFPE 精製ケミストリは テカン社 Freedom EVO® および サーモフィッシャー社 KingFisher™ Flex の各機器での自動化に適応します。キアゲン社 QIAamp® および GeneRead キットはQIAcube で標準法を用いて実行できます。ヒト肺がん組織および隣接正常組織の連続FFPE切片はすべての方法で組み込まれサンプルによるバラつきを低減するために繰り返し実施した。溶出液は蛍光検出法により定量し、ProNex® DNA QC Assayを用いて品質を評価した。

Yield of DNA Extracted from FFPE Tissues. Extracted DNA was quantitated using the QuantiFluor® ONE dsDNA System to ensure high accuracy. For both tumor and normal tissue, Maxwell® HT DNA FFPE chemistry yielded consistently greater amounts of DNA than other systems.

Amplifiability of fragments of various sizes using qPCR. After extraction, the ProNex® DNA QC Assay was used to assess the amplifiability of the DNA using three particular targets as an indication of the DNA integrity and thus suitability for downstream applications, including qPCR and next-generation sequencing. In both sample types and at all amplicon lengths, eluates derived from the Maxwell® HT DNA FFPE Isolation System were shown to provide greater amplification. 
Tissue Instrument Uniformity of Coverage (%) Mean Amplicon Coverage (X) Reads (millions)
Tumor Tecan 100.0 4818 1.08
KingFisher 99.19 6036 1.28
Normal Adjacent Tecan 100.0 5202 1.18
KingFisher 100.0 4074 1.05

Next-Generation Sequencing Performance of DNA Purified with Maxwell® HT Chemistry. DNA purified using Maxwell® HT chemistry on both Tecan and KingFisher instruments was sequenced using an Illumina MiSeq after enrichment using the Ion AmpliSeq™ Cancer Hotspot Panel v2. Coverage, uniformity and depth were extremely high for both methods and for both tissue types, showing the suitability of these eluates in NGS applications. Furthermore, subsequent variant analysis revealed that low-frequency variants in the KRAS and EGFR genes were detected in the tumor tissue samples, but not in the normal tissue samples.
