PathCards integrates data from 11 sources. This guide lists the various sources we integrate data from.

• Cell Signaling Technology - CST (Cell Signaling Technology) provides discovery tools for cell signaling research, including information about pathways and phosphorylation sites.
• GeneGo (Thomson Reuters) - GeneGo (Thomson Reuters) Maps are interactive pathways with consensus knowledge on signaling and metabolism involved in human biology and diseases
• MalaCards - MalaCards is an integrated database of human maladies and their annotations, modeled on the architecture and richness of the popular GeneCards database of human genes. MalaCards is searched for annotations to find for example related diseases (that mention each other in their cards), and related organs.
• PharmGKB - PharmGKB is an integrated resource about how variation in human genes leads to variation in our response to drugs
• PubChem - PubChem is an open chemistry database at the National Institutes of Health (NIH).
• QIAGEN - the leading provider of sample and assay technologies.
• R&D Systems - R&D Systems develops and manufactures high-quality proteins and serves as a world leader in immunoassays. R&D Systems also produces quality antibodies, antibody arrays, stem cell and cell culture products, and cell selection and detection products, serving the life science and diagnostics industry
• Reactome - Reactome provides curated knowledgebase of biological pathways in humans.
• Sino Biological - Sino Biological is committed to providing high-quality recombinant protein, antibody, cDNA clone and ELISA Kit reagents and to being a one-stop technical services shop for life science researchers around the world.
• Tocris - Tocris Bioscience is a leading supplier of high performance life science reagents, peptides and antibodies, with customers in virtually all of the worlds major pharmaceutical companies, universities and research institutes.
• WikiPathways - WikiPathways is a database of biological pathways maintained by and for the scientific community.
