PEL-FREEZ, LLC

PEL-FREEZ, LLC specializes in the manufacturing of biological products, with a demonstrated focus on human and rabbit complement systems—critical reagents used in immunological research, therapeutic development, and diagnostic assay validation. The company’s technical expertise lies in the production, purification, and quality control of serum-derived biological materials under controlled, GMP-aligned conditions, ensuring consistency and biological activity for sensitive downstream applications. Their specialization in complement proteins positions them as a niche supplier to research and pharmaceutical entities requiring highly specific, biologically active components for in vitro and preclinical studies. This capability requires deep knowledge of serum fractionation, pathogen inactivation, and sterility assurance protocols, distinguishing them in a highly regulated, low-volume market segment. The contractor has delivered products to the Department of Health and Human Services, indicating direct engagement with federal research and public health programs that rely on high-purity biological reagents for vaccine development, immune response characterization, or complement pathway studies. Their work supports mission-critical scientific initiatives requiring traceable, well-characterized biological materials, suggesting a trusted supplier relationship within HHS-affiliated laboratories or contracted research institutions. The primary NAICS code 325414 reflects active involvement in the manufacturing of biological products excluding diagnostics, placing PEL-FREEZ within the biopharmaceutical supply chain as a producer of raw biological materials rather than final therapeutics or devices. Their market positioning is that of a specialized manufacturer serving the research and development sector, particularly where complement proteins are essential for experimental reproducibility. As a small business structured under 2K (Small Disadvantaged Business), PEL-FREEZ operates from Rogers, Arkansas, with no federal certifications currently listed. Their geographic footprint is localized, but their product specialization grants them access to national federal research networks reliant on proprietary biological reagents.
