Proteios Technology, Inc.

Proteios is developing 1) recombinant protein purification kits and will soon be extending the technology for the purification of biopharmaceuticals during manufacturing, 2) a multivariate cell separation technology for cell enrichment during cell therapy research and a cGMP-compliant instrument for cell therapy manufacturing of autologous CAR-T cell therapies and allogeneic NK cell therapies, and 3) a POC device for the detection of the SARS-Cov-2 virus.
Proteios' vision is to apply our technology to help lower the cost of healthcare, including: diagnostics, small-molecule drugs, biopharmaceuticals, cell therapies, and gene therapies.

cGMP instrument for multivariate cell separation during cell therapy manufacturing
Cell therapies have emerged as highly promising treatments for cancers and diseases resulting from viral infection. We are designing a cGMP instrument for multivariate cell separation during cell therapy manufacturing, with an initial focus on T cells for autologous CAR-T cell therapies and Natural Killer cells for allogeneic viral and cancer therapies. Our technology avoids the use of antibodies and magnetics beads, and allows for cell separations based on multiple factors in a single step.
Category of Innovation
Life Sciences - Life science solutions are those solutions that are delivered as a drug or device that typically require federal approval

Provider - Individuals or organizations responsible for providing care to patients (e.g. doctors, nurses, hospital/clinic administrators, etc.)
Impactful Innovation Stage (Click Here for Details)
Problem (i.e. barrier, issue, complication, etc.) being solved for the end user
Current immunomagnetic cell isolation technologies are expensive, lack many GMP-grade reagents, employ antibody reagents with a short shelf life - resulting in inflexibility during planning, can take up to 10 hours to complete cell separation, and can only isolate cells based on selection of one cell surface antigen factor at a time. The latter results in back-to-back cell separations to be performed to isolate on two factors (e.g., CD4 & CD8 or CD3 & CD56) with an accompany 2x increase in cost and 2x increase in time.
Idea/solution to the problem, if applicable
Proteios' multivariate cell separation technology allows for the simultaneous selection of target cells based on multiple factors, resulting in a 75% reduction in cell separation time and 50% reduction in cost of reagents. The Proteios Chimera reagent is composed of a small synthetic polypeptide and synthetic DNA aptamer, and exhibits a long shelf life and is easily produced under GMP conditions.
