What VitaCyte does

VitaCyte, LLC is a privately held Indianapolis-based specialty life sciences manufacturer founded in 2003 that produces purified-defined collagenase and neutral protease enzymes used for cell and tissue dissociation. The company's core technology platform combines high-purity Clostridium histolyticum class I (C1) and class II (C2) collagenase isoforms with neutral proteases (BP Protease, thermolysin, clostripain) in precisely characterized mixtures produced via chromatographic purification and lyophilization under ICH Q7A-aligned GMP conditions. The portfolio spans >95% purity collagenases (Collagenase HA, MA, Gold, Gold Plus), animal-origin-free recombinant rCollagenase HI, purified proteases, and pre-blended application-specific mixtures (CIzyme RI for rodent islets, CIzyme AS for human adipose SVF) plus customizable PD Collagenase formulations. A proprietary kinetic fluorescent microplate collagen degradation activity (CDA) assay and analytical anion exchange chromatography method distinguish intact from degraded collagenase forms, enabling the lot-to-lot consistency and characterization documentation that competitors using only Wunsch or Mandl assays cannot match.

VitaCyte sells primarily to academic research institutions, commercial cell suppliers, and cell therapy companies manufacturing cells as therapeutic agents, with named relationships including the NIH-funded Clinical Islet Transplantation Consortium (CITCT), Nationwide Children's Hospital, and the University of Pittsburgh (Strom Lab) hepatocyte program. Revenue is generated through one-time catalog purchases of RUO and GMP Grade enzymes (priced $50-$2,250 per bottle across SKUs) and custom manufacturing services for commercial-scale customers. Distribution combines direct US sales through the company's website with a multi-region distributor network covering Europe (PELOBiotech), Japan (Cosmo Bio), SE Asia/China (FUJIFILM Wako), and Canada (Cedarlane), complemented by US distributors VWR and Fisher Scientific.

The company was co-founded by Robert McCarthy and Francis Dwulet, who contributed to the original purified collagenase-protease mixture underlying the Edmonton Protocol — the first successful islet transplantation therapy for adult Type 1 diabetes. Initial funding came from NIH NIDDK SBIR awards and Indiana state grants (21st Century Fund and SBIR matching awards); no institutional venture or private equity investment has been disclosed. Despite a 1-10 employee headcount, VitaCyte maintains GMP-aligned manufacturing, dedicated director-level leadership across Quality Assurance/Quality Control, Manufacturing, and Regulatory, and a substantial scientific content engine (technical posts, webinars, peer-reviewed publications) targeting cell isolation researchers.

Core offering

VitaCyte manufactures and supplies GMP Grade purified-defined Clostridium histolyticum collagenase and neutral protease enzymes for cell and tissue dissociation. The product portfolio includes purified collagenases (HA, MA, Gold, Gold Plus, rCollagenase HI), neutral proteases (BP Protease, Clostripain, Thermolysin), and application-specific mixtures (CIzyme RI for rodent islet, CIzyme AS for human adipose SVF; PD Collagenase 100/800). Products serve researchers, commercial cell suppliers, and institutions manufacturing cells as therapeutic agents, with custom manufacturing capabilities for commercial applications.

Product overview

VitaCyte manufactures the broadest line of purified-defined cell and tissue dissociation enzymes for research, cell therapy, and commercial applications. The portfolio includes: (1) Purified-Defined Collagenases (Collagenase HA, MA, Gold, Gold Plus, rCollagenase HI) with varying purity levels, GMP grades, and C1:C2 ratios for human islet, hepatocyte, and other cell isolation; (2) Purified Neutral Proteases (BP Protease, Clostripain, Thermolysin) that work synergistically with collagenases; (3) Application-Specific Mixtures (CIzyme RI for rodent islets, CIzyme AS for human adipose SVF) pre-blended for optimal performance in specific cell isolation procedures; and (4) PD Collagenase 100/800 (formerly DE Collagenase) - customizable purified-defined collagenase/protease mixtures. The key differentiator is enzyme purity (>95% vs. 4-25% in traditional crude/enriched products), enabling lot-to-lot consistency and eliminating the need for lot pre-qualification. Products are offered as research use only or GMP Grade for clinical applications.
