Cell Therapy Development Applications

Automated Cell Isolation for a variety of Cell Therapy types 

CAR-T Cell Therapy: T cell isolation

CAR-T Cell Therapy development requires a large number of well-purified T cells with high viability. CAR-T immunotherapy utilizes T cells engineered with CARs to effectively target and eliminate cancer cells.

T cells are collected from healthy donors (allogeneic therapy) or patient’s own blood (autologous therapy), genetically modified, and then administered to the patient to target a tumor surface antigen.

The first step in CAR-T cell production is to isolate T cells from human blood, which can be done either from the patient or a healthy donor. The cell manufacturing process is similar in both cases, with only the choice of initial blood donor differing.

Obtaining a significant number of T cells with high purity, recovery, and viability is crucial for pre-clinical testing on both small and large scales, as well as clinical applications, and requires a cell isolation solution.
MARS® Bar platform supports CAR-T Cell Therapy development providing small to large-scale cell therapy manufacturing solutions.

MARS® Ingenuity™ Line

MARS® platform is open, so users can choose the most suitable reagents or select one of the optimized solutions from our portfolio.

MARS® Ingenuity™ Line offers RUO and GMP reagents for use in CAR-T therapy cell separation and other Cell Therapy Development projects. The line consists of antibody directly conjugated, super paramagnetic nanometer-sized, biodegradable beads.

TCR Cell Therapy

TCR Cell Therapy has gained popularity due to the range of possible treatments for cancer it could offer. γδ T-cells have been shown to constitute promising effector cell compartments for cancer immunotherapy, because of their ability to recognize and kill transformed cell without dependending on HLA-antigen presentation.

Although published protocols for the isolation of a large portion of TCR cells in vitro exist, the purity of the final preparation between different donors is often heterogeneous. One solution is the use of column-free, immunomagnetic TCR α/β+ depletion, as demonstrated using MARS Bar Platform.

TCR therapy is still a relatively new, experimental treatment. We are supporting Cell Therapy development to help realize the full potential of TCR therapy and revolutionize cancer treatment.

Together with STEMCELL Technologies, we have developed a MARS MAG Premium Line of reagents, offering kits for single-step TCR α/β+depletion.

NK Cell Therapy

NK Cell Therapy utilizes engineered Natural Killer cells to target tumor cells and other diseases, and it is one of the most dynamically developing therapies. It involves isolation of NK cells from patient or other donot, NK cell modification and infusing it into patient’s blood stream for treatment. NK Cell Therapy has shown promising results in treating certain types of cancer, for example Leukemia, Lymphoma, or Multiple Myeloma.

Some of the key advantages of the NK Cell Therapy are increased therapy safety, multiple cytotoxicity mechanisms, and potential of the engineered NK cells to infiltrate into solid tumors. The success of NK Cell Therapy depends on the number and quality of NK cells used. MARS Bar platform enables the isolation of the NK cells from starting samples including Apheresis products and Whole Blood without the need of PBMC preparation. 

Our reagent MARS MAG Line and MARS MAG Premium Lines of reagents offer flexible beads and cocktails for positive or negative NK cell isolation for NK cell therapy development.

Stem Cell Therapy

Stem Cell Therapy involves the use of CD34+ cells with the potential to develop into different types of cells in the body. Examples of different types of stel cells include embryonic stem cells, induced pluripotent stem cells, or adult stem cells, all of which have unique potential for their use in therapy.

Intensive stem cell therapy development promises new cutting-edge treatments against diseases including some types of cancer, neurological disorders, cardiovascular diseases, wounds, and others.

The use of Stem cells in therapy is still a relatively new field, and intensive research is being conducted to fully understand its potential benefits and risks. MARS® Platform allows isolation of CD34+cells with high recovery, allowing for an efficient cell therapy development with a smaller input sample volume.
