Normal Blood, Bone Marrow and Buccal Mucosa Protocol

This protocol is designed to provide blood, skin, stool/rectal swabs, buccal mucosa and bone marrow aspirate samples from approximately 250 healthy volunteer donors for use in in vitro studies such as studies of cells of the immune system, mastocytosis, and allergic diseases. Participants will donate samples using conventional techniques. The investigational nature of the studies in which samples will be used, as well as the risks and benefits of the donation process, will be explained to all donors, and a signed informed consent document will be obtained. Donors will be compensated according to an established schedule based on the duration and discomfort of the donations. Samples provided through this protocol will be used solely for in vitro research. Samples will be assigned a unique product number, and the study investigators will serve as the custodians of the code that links the product with a donor s identity. The nature of the in vitro studies in which the blood collected in this study will be used is not the subject of this protocol and will be described in general terms only. The samples will be used in several Institutional Review Board (IRB)-approved Laboratory of Allergic Diseases (LAD) protocols. This protocol is designed to assure adequate and complete informed consent, counseling, and protection of the study subjects according to IRB, Office of Human Subjects Research Protections, Office for Human Research Protections (OHRP) and other applicable Federal regulatory standards.
