Our donors are at the heart of what we do at Leo Corps. Without donors we would have no product, so our priority is always to ensure that donors feel safe, comfortable, and confident in their choice to advance biomedical research. Our contracted, tissue-recovery organizations are chosen base on our strict quality guidelines making sure they follow AATB/AABB compliance rules and regulations and they are FDA-registered. By strictly screening donors, we are able to provide the highest-quality, tissue-based products to our clients for their research and development projects.

All donors must review and consent to sample collection. We screen donors based on age, sex, gender, BMI, blood type, medical history, social history, and other criteria. Based on these characteristics, donors may be disqualified from some studies, however, they can still donate to Leo Corps and its affiliated companies for other purposes.

If you are interested in becoming a donor today and furthering scientific advances around the world, please email us at info@leocorps.org. We follow HIPPA regulations and your identity will be kept confidential all the time.

Donor Selection

The availability of the appropriate donor(s) is critical for any study utilizing cell-based research. As a product moves through research and development to commercialization, the demand for donors that meet certain criteria accordingly increases. Leo Corps recruits a large pool of reliable and recallable donors. Our healthy, human leukocyte antigen (HLA)-typed donor pool consists of a wide range of well-characterized individuals with diverse demographics and other clinical parameters. Furthermore, through a robust donor pool and dependable network, Leo Corps provides researchers with access to the right donor in a timely manner for the advancement of research.
