Cell Therapy Systems Immunotherapy—T Cell and Dendritic
Cell Products

CTS Dynabeads CD3/CD28 mimic in vivo T cell activation via antigen-presenting cells. This gentle and efficient technology provides a trusted technology platform from which the beads can be used to isolate T cells and provide both the primary and costimulatory signals required for activation and expansion (Annu Rev Immunol 32:189 (2014); Nat Med 21:914 (2015); Mol Ther 15:355 (2007).) The Novartis chimeric antigen receptor T cell (CAR-T) cell therapy, Kymriah™ (tisagenlecleucel, formerly CTL019), is the first FDA-approved CAR-T immunotherapy, and uses specifically developed Cell Therapy Systems (CTS) Dynabeads technology.

• Isolate, activate, and expand your T cells ex vivo with just one product
• Harvest 100–1,000 fold expanded  T cells in just 9–14 days
• Recover T cells with properties comparable to in vivo–activated T cells

Optimized for regulatory T cells (Tregs), Gibco CTS Dynabeads Treg Xpander provides a more specific and higher-fold expansion of Tregs with superior cell yields and suppression of conventional T cells, which is essential for the treatment of autoimmune disease.

Key features:

• Scalable technology for robust activation and expansion of Tregs
• Aseptically manufactured and ready for clinical trials and commercial manufacturing
• >800-fold expansion at day 14 following stimulation at day 0 and day 9
• Expressed high percentage of FoxP3, CCR7, CD62L, CD45RO and CD45RA, and central memory phenotype markers

The Gibco CTS DynaMag Magnet facilitates efficient isolation of T cells in conjunction with CTS Dynabeads CD3/CD28 magnetic beads in closed, sterile blood bags (Cytotherapy16:619 (2014)).

• Isolate bead-bound cells, for example for subsequent stimulation/expansion of T cells with CTS Dynabeads CD3/CD28 and for removal of the beads following the expansion protocol
• Ideal for magnetic isolation in closed, sterile blood bags and tubing systems
• Remove unwanted cell types by discarding the magnetic captured bead-bound cells

The CTS LV-MAX Lentiviral Production System offers a scalable high-titer lentiviral vector production platform. This system includes HEK 293–derived suspension cells, serum-free media, proprietary transfection reagent, supplement, and enhancer. It can produce up to 10X more lentivirus, cutting costs by more than half compared to using polyethyleneimine (PEI)–based lentiviral production methods.

• Cost effective—reduce lentiviral vector production costs by up to 50% 
• High titers—greater than 1 x 10⁸ TU/mL (unconcentrated)
• GMP manufactured—seamlessly transition from research  to commercial production

Our GMP-banked CTS Viral Production Cells are derived from the human embryonic kidney (HEK) 293 cell line and were adapted to suspension culture in a chemically defined medium. These cells were developed to support cell and gene therapy applications, particularly intended for viral vector manufacturing.

• Extensive documentation of cell line lineage
• Absence of SV40 large T antigen
• Supports >10 million cells/mL in chemically defined medium

CTS Immune Cell Serum Replacement (SR) is designed to support expansion of in vitro cultured human immune cells such as T cells. A defined xeno-free formulation proven for clinical use and designed to support expansion of in vitro cultured human T cells when added as a supplement to a basal cell culture medium such as Gibco CTS OpTmizer T Cell Expansion SFM or AIM V Medium.

• Minimizes the supply and safety risks associated with human serum and can be used with the base media of your choice
• Supports expansion, efficacy and resistance of lentiviral gene-modified CAR T cells
• Supports T cell phenotype (CD4, CD8, and CD62L) similar to human serum

A complete serum-free, xeno-free medium formulation proven for clinical success and specifically developed for the growth and expansion of human T lymphocytes. CTS OpTmizer T Cell Expansion SFM is now available without phenol red.

• Supports high density T cell culture
• Supports phenotype, function and viability similar to T cells cultured with conventional medium supplemented with human AB serum
• Now supplied in a 1L enclosed bag facilitating work in GMP environments

Gibco CTS AIM V Medium is a fully defined serum-free formulation for proliferation and/or manipulation of T cells, dendritic cells, and other primary or immortalized cells. It contains L-glutamine and is formulated with or without phenol red and antibiotics, making it ideal for clinical applications.

• Tested for adventitious agents
• FDA-cleared class II medical device
• Supports expansion of human dendritic cells and other immune cells, including CAR T cells

The Applied Biosystems PureQuant Assays offer an alternative to flow cytometry to accurately identify and quantify CD8+ T cells, regulatory T cells (Treg) and T helper cells (Th17) in a mixed population. These TaqMan® qPCR-based assay kits measure genomic DNA methylation at specific sites that serve as a unique cell type specific identifier. Assays include all reagents, standards and controls. 

• Facilitates regulatory filings—shorten development timelines; established performance specifications following ICHQ2(R1) guidelines
• Proven technology—used for immune cell identification and quantification for over a decade
• Easily standardized—consistent results across multiple users, instruments, and sites
• Scheduling flexibility—run fresh cells, frozen cells or gDNA at your convenience

Gibco Cell Therapy Systems CTS DPBS is the classical Dulbecco’s Phosphate Buffered Saline not containing calcium, magnesium or phenol red.

• Provides an environment that maintains the structural and physiological integrity of cells in vitro
• Chemically defined and animal origin–free materials suitable for use in clinical research studies
