iPSC Therapy Solutions

Regulatory bodies like the FDA recognize the safety concerns of off-target cleavage events when using CRISPR-Cas9, particularly for therapeutics applications. To address these safety risks, there is a developed CTS HiFi Cas9 Protein, a GMP-manufactured high-fidelity Cas9 protein designed to significantly reduce off-target events while maintaining high editing efficiency.

• Significantly reduce off-target effects—>90% reduction in a broad range of cell types including primary immune cells
• Equivalent editing efficiency—Achieve the same high editing efficiency as CTS TrueCut Cas9 Protein, our wild-type protein designed for exceptional on-target editing efficiency
• Improved knock-in efficiency—Also offered in CTS HiFi Cas9 and CTS Xenon Genome Editing Buffer Kit to offer 2X improved knock-in efficiency

The next-generation Cas9 protein is now available in a Cell Therapy System (CTS) formulation, CTS TrueCut Cas9 Protein, for large scale clinical research.

• Exceptional performance—Consistently high performance in all tested cell lines, including >90% editing in iPSCs
• Higher stringency manufacturing—Manufactured in compliance for Ancillary Materials for Cell, Gene, and Tissue-Based Products
• Extensive safety testing—Including sterility, endotoxin, mycoplasma, residual host nucleic acids, and proteins

Based on the widely cited Essential 8 Medium, Gibco CTS Essential 8 Medium was the first globally available human pluripotent stem cell (hPSC) culture medium with components not directly derived from animals.

• Supports long-term iPSC culture—Maintains iPSC marker expression and a normal karyotype over multiple passages
• Maintains differentiation potential—PSCs cultured in CTS Essential 8 Medium are able to generate cells of all three germ layers
• Helps reduce risk—Based on the same fully defined and highly consistent eight-component formulation as research-use Essential 8 Medium but without components directly of animal or human origin

Gibco CTS KnockOut SR XenoFree Medium is a defined, xeno-free serum replacement based on the traditional KnockOut Serum Replacement, which has been cited in more than 2,000 publications and trusted for over 20 years.

• Supports pluripotency—Able to maintain the pluripotency, normal morphology, and karyotype of hPSCs
• Versatile—Can also be used for cryopreservation, derivation, and differentiation of iPSCs
• Designed for your applications—A first-to-market, xeno-free iPSC product

Designed in the laboratory of James Thomson, Gibco CTS Vitronectin (VTN-N) Recombinant Human Protein is a defined matrix for feeder-free culture of pluripotent stem cells (PSCs) and is designed for clinical research.

• Animal origin-free—Reduced variability and contamination risk in PSC cultures.
• Optimized—Intended for use with CTS Essential 8 Medium
• Consistent—Supports transition from RUO Vitronectin

Gibco CTS Versene is a gentle non-enzymatic cell dissociation reagent for routine clump passaging of PSCs while maintaining viability over multiple passages.

• Maintain viability over multiple passages—PSCs passaged with this cGMP manufactured EDTA dissociation reagent maintain viability
• Designed with transition in mind—Same formulation as RUO Versene Solution but with additional characterization and quality control testing

Your choice of chemically defined human- and animal origin-free basal media for pluripotent stem cell culture. Based on traditional DMEM and DMEM/F12 formulations, these basal media are:

• Optimized—Lower osmolarity as compared to traditional formulations improve maintenance of undifferentiated iPSCs
• Versatile—Have been shown to support expansion and differentiation of a variety of stem cells, including iPSCs
• Tried and tested—Cited in many publications, often used with CTS KnockOut SR XenoFree supplement

Gibco CTS RevitaCell Supplement (100X) is an animal-origin-free, chemically defined supplement used with PSCs for post-thaw recovery or in combination with CTS Essential 8 Medium for single cell passaging.

• Improved cell survival—Provides high cell viability post-single cell passaging and post-thaw
• Contains higher specificity inhibitor—Includes a higher specificity ROCK inhibitor, coupled with antioxidants and free radical scavengers to minimize impact of stress on cells
• Offers consistency—Formulated using animal-origin free and chemically defined materials

The Gibco CTS PSC Cryopreservation Kit, which includes CTS PSC Cryomedium and CTS RevitaCell Supplement, minimizes the loss of cell viability and maximizes post-thaw recovery of PSCs.

• Provides efficient recovery—Routinely achieves higher viability than traditional methods of PSC cryopreservation
• Offers consistency—Chemically defined media maintains normal morphology, pluripotency, and karyotype of PSCs
• Reduces variability—Optimized reagents minimize the causes of genetic instability of PSCs

Gibco CTS Essential 6 Medium is a xeno-free, feeder-free medium which supports the spontaneous or directed differentiation of hPSCs and the reprogramming of somatic cells.

• Provides a flexible format—Suits different applications and various cell types
• Supports differentiation and reprogramming—Does not contain bFGF or TGFbeta
• Simplifies the transition from bench to clinic—Contains the same six essential components as RUO Essential 6 Medium, and with its cGMP manufacturing process, this formulation helps minimize variability
