Human T Cell Depletion Kit – CR (5 Billion Cells)

SKU:
13510-232CR
Categories: ,

With quality standards built into the design and manufacturing process at every step, Akadeum’s Human T Cell Depletion Kit – CR uses microbubbles to remove unedited T cells from CAR T cultures. Unwanted T cells expressing CD3 are positively isolated using a cocktail of biotinylated anti-CD3 antibodies, which are then captured using our buoyant Depletion Microbubbles that gently float to the top of the sample. This leaves a highly pure sample of engineered cells untouched and ready for downstream formulation. The highly scalable nature of this process means that it can easily be incorporated into a wide variety of cell therapy manufacturing workflows.

  • Efficiently deplete CD-3 expressing cells quickly without losing precious engineered cells
  • Flexibility to integrate into many existing workflows
  • Increase recovery of gene-edited cells for downstream formulation
  • Gentle process maintains the health of the cell therapy product
  • Akadeum CR products are manufactured according to cGMP under a quality management system in compliance with 21 CFR 820, 211, and 210. They are developed following USP <1043> recommendations on ancillary materials and tested according to ISO 20399 and ISO 10993.

Mechanism of Action: When developing CAR T cell therapies, the ability to isolate pure populations of engineered cells after transduction is paramount. Cells still expressing CD3 can be harmful to the patients receiving these therapies. The Human T Cell Depletion Antibody Cocktail – CR recognizes the CD3 epitope using multiple, non-overlapping anti-CD3 clones for enhanced performance. CD3+ cells are labeled with antibodies, which are bound by the BACSTM Depletion Microbubbles – CR and removed from the sample using buoyancy. Unlabeled and successfully transduced CD3 negative cells are recovered by removal of microbubble-bound CD3+ cells, ready to use for downstream applications.

How it Works: Akadeum’s process offers an elegant solution for highly effective and scalable T cell depletion. Biotinylated anti-CD3 antibodies bind to untransduced T cells still expressing the CD3 epitope. Streptavidin coated Depletion Microbubbles – CR then selectively bind to the antibodies labeling the undesired cells. Due to the natural buoyancy of the microbubbles, they naturally float to the surface of the culture vessel pulling along CD3+ cells. The positive cells can then be easily extracted off the surface with the microbubbles leaving engineered cells untouched to settle to the bottom of the vessel.

Key Features

Akadeum’s Human T Cell Depletion Kit – CR provides large quantities of highly pure engineered T cells by efficiently removing CD3+ cells. The microbubble technology enables scalable processing and yields highly viable cells with high engineered T cell recovery rates. Akadeum’s novel approach to CAR-T cell purification offers the flexibility necessary for rapid optimization for cell therapy workflows.

Elegant in Simplicity, Powerful in Application

BACS™ Microbubble technology harnesses the power flotation to streamline your cell therapy workflow. Our novel technology couples performance, ease, and quality, bringing a new dimension to your cell culture.

What are the advantages of Akadeum’s BACS™ workflow?

  • Scalable to fit your cell therapy workflows
    • The Microbubbles in the Human T Cell Depletion kits can process a wide range of cell numbers; from below 10 million cells to quantities up to 5 billion.
  • Highly pure sample of CD3 negative cells post-depletion
    • The Human T Cell Depletion Kit – CR removes more than 95% of CD3+ cells leaving highly concentrated transduced cells behind.
  • Increased recovery of gene-edited cells for downstream formulation
    • Due to the properties of the bubbles and a positive selection of the CD3+ positive cells, more engineered cells are recovered after isolation.
  • Gentle process maintains the health of the cell therapy product
    • Leaving the cells of interest untouched leaves them in a viable state without harsh processing giving better starting material for formulation and eventually cell therapy.
  • Clinical Ready kits offer assurance of quality and strict standards
    • Akadeum’s Clinical Ready manufacturing follows 21 CFR 820, 211, and 210 while also testing according to ISO 10993. Production is also compliant with ISO 20399 – Biotechnology – Ancillary materials present during the production of cellular therapeutic products and gene therapy products and USP <1043>. Testing includes but is not limited to:
      • Biocompatibility Acute Systemic Toxicity
        • Hemolysis
        • Sensitization
        • Thrombogenicity
