優れた蛍光染色性
色素希釈による増殖分析を成功させるには、数回の細胞分裂後に蛍光標識された細胞を自動蛍光と区別するために、非常に明るい色素が必要です。CellTrace™ Far Red色素によって提供される強力な蛍光染色により、シグナルが細胞固有の自家蛍光によって妨害される前に、6世代以上の増殖細胞の可視化が可能となります。このキットを使用すると、集団内の細胞間の蛍光変動がほとんどなく、一貫し均質な染色結果を得られるため、複雑なモデリングソフトウェアがなくても特徴的な世代を確認できます。

長期の信号保持
細胞の脂質膜を標識する染色とは異なり、CellTrace™ Far Red染色剤は容易に細胞膜を通過して細胞内で共有結合し、安定が高く保持力のある蛍光色素は、細胞培養環境で数日後でも一貫してシグナルを提供します。CellTrace™色素は、細胞表面および細胞内部のすべての遊離アミンと共有結合し、細胞毒性をほとんど示さず、細胞増殖能や生態への影響は最小限に抑えられます。

他の蛍光体とのマルチプレックスが容易
CellTrace™ Far Red色素の630 nmでの赤色励起および661 nmでの発光は、他の一般的な色素(Alexa Fluor™ 488、FITC、RPE)および蛍光タンパク質(Green Fluorescent Protein(GFP)およびmCherry)とのスペクトルのオーバーラップが限られているため、マルチプレックスに理想的です。

シンプルで堅牢な染色プロトコル
CellTrace™細胞増殖キットには、過剰量の色素を調製せずに小規模な実験ができるように、便利な乾性色素の単回使用バイアルが含まれています。使用前に、バイアルの内容物を無水DMSOに溶解してストック溶液を調製します。タンパク質フリー培地中の細胞1 mLを染色するのに、通常このストック溶液1 µLを使用します。細胞を室温で緩やかに撹拌して20分間染色する必要があります。完全培地で短時間洗浄して、溶液中に残っている色素を消光させます。
研究用にのみ使用できます。診断用には使用いただけません。

  • よくあるご質問(FAQ)

    I want to do a cell migration study for around 4 hours and need to fluorescently label the cells with a dye. What do you recommend?

    Calcein, AM and FDA (fluorescein diaceate) are examples of some dyes used for this application. Since these dyes are not incorporated or covalently attached to any cellular components, they may have a short retention time as some cell types may actively efflux the dye out of the cells. The CellTracker and CellTrace dyes include either a mild thiol-reactive chloromethyl group or amine-reactive succinnimidyl ester group to allow for covalent binding to cellular components, providing for better retention. As with any reagent, one should empirically determine retention times for the cell type used.

    I labeled my cells with Calcein, AM, but when I imaged the next day, there was no fluorescence from Calcein. Why?

    Calcein, AM is a good choice for cell tracking and as a general cytoplasmic stain. However, it doesn't bind to anything and may be actively pumped out of the cells within a couple hours, which is likely what happened. The retention of Calcein within live cells is dependent upon the inherent properties of the cell type and culture conditions.

    For long-term imaging, you may wish to consider a reactive cytoplasmic stains such as CFDA, SE or the CellTracker and CellTrace dyes.

    Can the CellTrace Far Red dye be fixed with paraformaldehyde (PFA)?

    Yes, the CellTrace Far Red dye can be fixed with paraformaldehyde (PFA). The dye covalently binds to cells and will not wash out after permeabilization or fixation.

    I would like to label two cell populations with two different CellTrace reagents and then co-culture these cells. Will the CellTrace reagent leave the cells to stain other cells?

    We have not tested the use of the CellTrace reagents for co-culture applications. In theory, this may work, but you would have to test this on your cells of interest.

    With the CellTrace cell proliferation kits, for flow cytomtery, I am getting only one broad peak on my histogram instead of multiple peaks. What is causing this?

    A single broad peak is usually caused by using too high a concentration of dye and/or too long an incubation time.
