Invitrogen TrueCut Cas9タンパク質v2は、ゲノム編集の効率を最大化するために開発された次世代のCRISPR Cas9タンパク質です。次の特長があります。

•スタンダード、免疫、初代、幹など、すべての試験済み細胞株において一貫して高い編集効率。厳しいターゲットでは、編集効率が競合製品よりも最大2倍になります
• 高品質 — 厳しいISO 13485品質基準での製造
• 多数の細胞タイプ用の検証済みプロトコルが、目標の達成を加速します

TrueCut Cas9タンパク質v2は組み換え化膿連鎖球菌Cas9(wt)タンパク質で、CRISPRテクノロジーでの遺伝子編集のために大腸菌から浄化されます。Cas9タンパク質は、CRISPR/Cas9システムのガイドRNA(gRNA)コンポーネントと非常に安定したリボ核タンパク質(RNP)複合体を形成します。結合された核移行シグナル(NLS)が、核への移行をスムーズにし、ゲノムDNAの切断効率を高めます。

•脂質を介したトランスフェクション試薬またはエレクトロポレーションを使用して、トランスフェクショングレードを実現
• 時間のかかるクローニング手順を排除
• 2種類の濃度で利用可能:
    --1 μg/μL:標準的な編集シナリオでの使用に対応
    --5 μg/μL:初代細胞や胚細胞、マイクロインジェクション、複数のgRNA配列を同時にスクリーニングする場合など、より困難なシナリオでの編集条件の最適化に対応
    --カスタムサイズやカスタム濃度については、お問い合わせください

TrueCut Cas9タンパク質v2で使用するCRISPR gRNAを入手するためのオプション:
1.トランスフェクショングレードのTrueGuide合成gRNAを注文する
2.お客様ご自身で、GeneArt Precision gRNA合成キットを用いてテンプレートをアセンブリしてトランスフェクショングレードのgRNAを作製する(所要時間4時間)
3.弊社国内の受託サービスチームが配列をデザインし、in vitro(IVT)でgRNA合成および精製を行い、お客様にお届けする(所要時間約1週間)

研究用途にのみご使用ください。診断目的には使用できません。

よくあるご質問(FAQ)

What is the molecular weight of TrueCut Cas9 Protein v2?

The molecular weight of TrueCut Cas9 Protein v2 is ~163 kD

What is the difference between TrueCut Cas9 Protein (Prototype) and TrueCutCas9 Protein v2?

Both products are the same CRISPR-Cas9 protein, but the TrueCut Cas9 Protein is manufactured with a new production process and formulated to meet the standards for Ancillary Materials for Cell and Tissue-Based Products.

Is there a specific antibody that you recommend to test the delivery of TrueCut Cas9 Protein v2?

Although we do not have a specific antibody recommendation to test the delivery of TrueCut Cas9 Protein v2, we have tested the following antibodies against an older version of Cas9 (Platinum Cas9) using U2OS-Cas9 expression cell lines (generated using Cas9 lentivirus):
- Cas9 Recombinant Polyclonal Antibody (Cat. No. 711061)
- Cas9 Monoclonal Antibody (Cat.No. MA1-201)
- Cas9 Monoclonal Antibody (Cat. No. MA1-202)

Our TrueCut Cas9 Protein v2 and the Platinum Cas9 have similar domains, and the TrueCut Cas9 Protein v2 has better efficiencies. Therefore, these antibodies should work with TrueCut Cas9 Protein v2 as well.

What is the storage buffer composition for TrueCut Cas9 Protein v2 and TrueCut HiFi Cas9 Protein?

The storage buffer composition for TrueCut Cas9 Protein v2 and TrueCut HiFi Cas9 Protein is as follows:
15 mM Tris-HCl pH 8.0, 150 mM NaCl, 1.0 mM TCEP, 50% glycerol.

Which lipid transfection reagent do you recommend using with TrueCut Cas9 Protein v2 and TrueCut HiFi Cas9 Protein?

We recommend using Lipofectamine CRISPRMAX Transfection Reagent with TrueCut Cas9 Protein v2 or TrueCut HiFi Cas9 Protein.
