SVGの手法を適用する際に重要な多くの要因を考慮しなければならない。ジェノタイピングは、概念実証実験13の間に行われたように、保存されたプライマーはすべてのウイルスのグループ間で利用できないなどの環境や未知の分離のための有効なオプションではありません。また、バックグラウンドDNA合成又は非特異的な増幅は、一般的にMDA反応14を用いて増幅中に報告され?...

isolation and genome analysis of single virions using 'single virus genomics'

単一の微生物細胞の全ゲノム増幅および配列決定は、栽培1-3を必要とせずにゲノム特性評価を可能にします。ユビキタスと私たちの惑星4上で最も数多くのエンティティとすべての環境5で重要であるウイルスは、同様のアプローチを介して明らかにされていない。ここでは、 &#39;シングルウイルスゲノミクス&#39;（SVG）と呼ばれる単一のビリオンのゲノムを単離し、特徴付けるためのアプローチについて説明します。 SVGは、その後の配列決定反応に用いることができる高分子量のゲノムDNA（gDNAを）を得るために、個々のウイルスおよび全ゲノム増幅を分離するためにフローサイトメトリーを利用する。

Isolation and Genome Analysis of Single Virions using 'Single Virus Genomics'

単一のウイルスゲノム（SVG）は、単一のビリオンのゲノムを分離して増幅する方法である。混合された集合体のウイルス懸濁することにより、ビリオンを捕捉し、下流の処理中にゲノムせん断を低減、アガロースを含む個別のウェルを有する顕微鏡スライド上にフローサイトメトリーを用いてソートされる。全ゲノム増幅は、配列決定のために適しているゲノム材料をもたらす複数の置換増幅（MDA）を用いて達成される。
