Cell Engineering

We support both autologous and allogeneic cell engineering

Today, cell engineering is one of the most successful applications of advanced medicine. Porton Advanced offers both autologous and allogeneic cell engineering platforms with integrated supports including CRO service, process development, analytical development, cGMP manufacturing, testing services, and regulatory assistance.

In autologous cell engineering, T cells are collected from the individual patient. This includes CAR-T, TCR-T, TIL, etc.
In allogeneic cell engineering, Cells are obtained from healthy donor pools, such as UCAR-T, NK/CAR-NK, γδ T, red cells, MSC, IPSCs, etc.

PROCESS DEVELOPMENT FOR cell engineering

Support of over 11 types of cell engineering

Porton Advanced has developed a mature process platform and has accumulated rich CMC experience for different types of cell engineering. At the same time, we continue to invest resources in optimization and development of new process technologies to meet the needs and challenges of industry development.

Process platforms dedicated for different types of cell engineering

Porton Advanced has established numerous types of cell engineering-related processes and platforms. Our team can deliver, with efficiency and high-quality, various types of customized products.

Process platforms for multiple cell engineering types

For CAR-T or TCR-T, lentiviral static transduction is usually used without the addition of transduction enhancers. The VCN (Vector Copy Number) of healthy CD3-positive cells is controlled to be no more than 3, and CAR or TCR positive rate is 60~90%.

According to various client request, Porton Advanced designs and explores optimal electroporation proecess for efficiently knock-in/out target genes by numerous electroporation equipment (including Lonza, Thermo, Etta and so on).

To reach specification of cell engineering excipients, Porton Advanced can perform irradiation on feeder cells by our own irradiation equipment.

CGMP cell engineering MANUFACTURING

Supporting from pre-IND to clinical trials

Porton Advanced has successfully obtained clinical approval for 8 IND applications since the launch of our first cell engineering cGMP production line back in 2020. We now provide CDMO services for dozens of cell engineering projects at varying stages such as investigator-initiated trials, preclinical trials, IND applications, clinical trials, and more. So far, Porton Advanced has 12 independent production lines, which allows us to simultaneously produce autologous cell products, allogeneic cell engineering products, and cell engineering products with more closed operations.
