Erythrocytes transport oxygen and CO2 to various parts of the body. They are able to do this because they contain Hemoglobin. Additionally, Erythrocytes are important in the maintenance of the acid-base balance within the body. First Choice Bio’s Healthy Human Donor Peripheral Blood Erythrocytes are collected by density gradient. All peripheral blood is collected from fully consented donors that tested negative for HIV, HBV, and HCV.

All protocols are IRB approved.
