CTS™ Detachable Dynabeads™ CD3/CD28
The CTS™ Detachable Dynabeads™ CD3/CD28 (SKU A56996) must be used with the CTS™ Detachable Dynabeads™ Release Buffer (sold separately) in order to trigger the active release mechanism. The Release Buffer has three separate sizes (catalog SKU # A5588301, A5588302, or A5588303) and may be purchased on ThermoFisher.com.

Gibco CTS Detachable Dynabeads CD3/CD28磁気ビーズは、ex vivoでのT細胞の分離と活性化をワンステップで行うように設計されています。この製品をCTS Detachable Dynabeads Release Buffer(製品番号A55883)と併用することにより、これまでにないcGMP細胞選択技術が実現します。この技術は、プロセス開発、臨床試験、および商用生産で使用できるリリース機能(標的細胞からのビーズの取り外しをコントロールできる機能)を備えています。

CTS Detachable Dynabeads CD3/CD28の特長:

  • 標的細胞からビーズをいつでも取り外しできるリリース機能により、プロセスの柔軟性をユーザーに提供
  • リリース機能によりユーザーはより細かく制御できるため、標的細胞の純度、収率、活性化プロファイルおよび望ましい表現型お最適化が容易
  • CTS DynaCellect Magnetic Separation Systemと直接連携して自動化に適したソリューションを提供
  • プロセス内の生物学的変動を考慮して、一貫したパフォーマンスを実現します
  • 自家細胞治療および同種他家細胞治療の製造プロセスの両方に適合

これらのDynabeads磁気ビーズは、CD3およびCD28細胞表面マーカーを標的とするラクダ科由来の単一ドメインVHH抗体でコーティングされており、T細胞の活性化と増殖に必要な一次シグナルおよび共刺激シグナルの両方を提供これらのDetachable Dynabeadsは、CTS Detachable Dynabeads Release Bufferと一緒に使用するように設計されています。このバッファーは、ビーズ表面のビオチン誘導体を競合的に置換する有効成分であるビオチンを含有しています。この独自のメカニズムにより、ユーザーはプロセス内でいつでも標的細胞からビーズをリリースできます。

推奨される3:1のビーズ対標的細胞比(総有核細胞数ではない)に基づくと、1本(10 m L入り)バイアルは理論的に最大1.33 x 109個のT細胞を分離および活性化できます。

細胞ベース、遺伝子ベース、または組織ベースの製品の研究での用途または製造。注意:ヒトまたは動物への直接投与は意図されていません。

よくあるご質問(FAQ)

What is the definition of superparamagnetic, and what does this mean for my cell isolation application with Dynabeads magnetic beads?

Superparamagnetic means that the Dynabeads magnetic beads exhibit magnetic properties when placed within a magnetic field, but have no residual magnetism when removed from the magnetic field.

This means that your targeted cells, proteins, or nucleic acids are only subjected to magnetic forces during the time the beads are on the magnet. The beads do not aggregate, but remain evenly dispersed in suspension.

What are the shipping and storage and conditions for CTS Detachable Dynabeads CD3/CD28 (Cat. No. A56996)?

CTS Detachable DynabeadsCD3/CD28 (Cat. No. A56996) is shipped at 2-8 degrees C. We recommend storing it at 2-8 degrees C, protected from light.

As CTS Detachable Dynabeads CD3/CD28 (Cat. No. A56996) and CTS Dynabeads CD3/CD28 (Cat. No. 40203D) bind to both CD3 and CD28 markers, does that mean that CD3 positive CD28 negative cell subsets are excluded from the positive fraction?

Yes, CTS Detachable Dynabeads CD3/CD28 (Cat. No. A56996) and CTS Dynabeads CD3/CD28 (Cat. No. 40203D) preferentially isolate CD3+ CD28+ double-positive T cells, which are demonstrated to contain the clinically relevant subset of T cells (i.e., CD27 positive, PD-1 negative, CD8 positive CAR T cells).

Also note that CTS Dynabeads is the only isolation technology on the market that excludes exhausted T cells from the manufacturing of the T cell drugs. Please see this reference from University of Pennsylvania & Novartis that used CTS Dynabeads CD3/CD28 in a clinical study of patients with Chronic Lymphocytic Leukemia (CLL): https://pubmed.ncbi.nlm.nih.gov/29713085/

Are there potential risks to patient safety when using CTS Dynabeads or CTS Detachable Dynabeads?

Unlike magnetic beads from our competitors, CTS Dynabeads are not phagocytosed by T cells or incorporated into patients. CTS Dynabeads are inert to T cell phagocytosis and can therefore be removed (using the CTS DynaCellect Magnetic Separation System, Cat. No. A55867) before the final drug is injected into the patient.

There is also no evidence that CTS Dynabeads activate T cells non-specifically. Adding Dynabeads without antibodies, for example, to cell suspensions does not upregulate activation markers nor induces expansion.

What are the antibodies on the surface of CTS Detachable Dynabeads CD3/CD28 (Cat. No. A56996)?

CTS Detachable Dynabeads CD3/CD28 (Cat. No. A56996) are coated with camelid-derived, single-domain (VHH) antibody fragments that identify and bind CD3 and CD28 markers, separately. These antibodies are produced in an Animal origin Free (AOF) yeast-based system, helping to reduce any risk of viral contamination.
