Protheragen offers a wider variety of 13C/14C-labeled compounds, supporting research in metabolic pathways, pharmacokinetics, breath assays, and biochemical tracing.

New York, USA - November 12, 2025 - Protheragen has expanded its 13C/14C-labeled compound portfolio to support research in metabolic pathways, pharmacokinetics, breath assays, and biochemical tracing. The expanded lineup improves options for high-accuracy molecular tracing and supports consistent data output in metabolism and drug distribution research. Researchers can now explore a broad selection of 13C- and 14C-labeled products designed to meet a wide range of experimental needs.

Accurate metabolic and pharmacokinetic studies rely on labeled compounds that retain native biochemical behavior, allowing researchers to trace molecular transformations without perturbing normal pathways. This approach is widely used in preclinical pharmacokinetics, metabolomics, and clinical assays. For example, specialized 14C-labeled lipids and steroids allow researchers to trace lipid and steroid metabolism with precision, providing deeper insight into their regulatory roles in the body.

Protheragen's extended range comprises several types of labeled compounds, giving researchers more flexibility in their studies. 14C intermediates can be used to label drug molecules or trace the structure of new compounds. 14C sugars help scientists study how cells use energy and regulate glycan-related pathways. 14C lipids and steroids are useful for exploring lipid metabolism, hormone activity, and signaling pathways. The company also provides labeled kits for metabolic studies and breath tests, supporting both research workflows and clinical assay development.

Maintaining reproducibility and batch-to-batch consistency is essential when using labeled compounds in research. Protheragen applies standardized synthesis methods and confirms each compound's structure through analytical testing, maintaining quality that is both reliable and fully traceable. Protheragen can also support customized labeling requests, offering flexibility to meet specific experimental needs and ensure clear, interpretable results.

"In research on metabolism and pharmacology, having consistent batches is crucial to the reliability of long-term results," said a product development representative from Protheragen. "We regularly update our isotope labeling procedures and quality control measures, and carefully test each batch so that results remain consistent across ongoing research projects."
