Biological Use Authorizations

Principal investigators must first obtain a Biological Use Authorization (BUA) from the Institutional Biosafety Committee (IBC) in order to conduct research with the following materials and/or strategies:

BUA Approval Process

Principal investigators are responsible for completing the BUA form and assessing the risks associated with the biological materials and experimental procedures.

The biosafety officer reviews applications to ensure that the materials and procedures are described with enough detail for the IBC to prescribe or affirm containment measures. The IBC meets on the second Wednesday of the month during the academic year. Agenda items are sent out one week before the IBC meets.

The biosafety officer emails the principal investigator and lead contact with questions or recommendations from the IBC. Upon finalization of the BUA, the biosafety officer emails a letter of approval with the BUA title, tracking number, expiration date, biosafety level of containment, applicable section(s) of the NIH Guidelines, training requirements, and any occupational health recommendations or requirements. BUAs are effective for 3 years from the date of the letter of approval.


Registering Work with Human Cell Lines

Human cell lines that are derived from apparently healthy donors and screened for a panel of the most common bloodborne pathogens are considered well characterized. Well characterized human cell lines are accompanied by a Certificate of Analysis from the vendor indicating that the cells have been screened and found to be negative for, at a minimum, hepatitis B virus, hepatitis C virus, and the human immunodeficiency virus. The Certificate of Analysis documents reduced concerns for the presence of bloodborne pathogens by ruling out the main pathogens that have been encountered in hospital settings. The panel of bloodborne pathogens is specific to the vendor and varies slightly.

Principal investigators register their work with well characterized human cell lines with the IBC via the biosafety officer using the standard BUA form. Use of such cell lines does not require IBC review or approval before work begins.

The California Department of Public Health does not designate well characterized human cell lines as medical waste.
• See California Health and Safety Code Sections 117600 – 118360, specifically, 117700 (a) and (b), for biological materials excluded as medical waste.

The Occupational Safety and Health Administration exempts well characterized cell lines from the Bloodborne Pathogens Standard.
• OSHA Standard Interpretation issued 1994:

For established tumor cell lines, human or NHP origin does not intrinsically make them medical waste unless there is information about contamination with pathogens or integration of non-defective pathogenic viral sequences.

Changes to Approved BUA Applications

Changes to the project, e.g., additional research personnel, biological materials, or facilities shall also be registered with the IBC. Changes or additions that increase the risk of the project are reviewed and approved by the IBC at the regular monthly meeting. Use MS Word Track Changes within the originally approved BUA to note amendments.


Additional Oversight

Please note that additional oversight may be necessary from one or more of the following agencies or committees:

Animal and Plant Health Inspection Service/Centers for Disease Control (APHIS/CDC)

Principal investigators (PIs) must register the use of select agents and/or toxins with APHIS/CDC if they are to possess amounts exceeding the current permissible quantities. If there is no permissible toxin amount listed, then you should infer that registration for the possession of any amount is required. In practice, APHIS/CDC registration is obtained prior to submitting a BUA application.

Institutional Use and Animal Care Committee (IACUC)

PIs must also register live animal studies with IACUC. IACUC ensures that all activities involving live vertebrate species meets the ethical and legal requirements for the humane care and use of animals as set forth by the Public Health Service Policy, the Animal Welfare Act, and UCSB policies and guidelines. Protocols involving animals should be registered first or concomitantly with the IBC.

Stem Cell Research Committee (SCRO)

SCRO oversees human stem cell research in order to ensure that UCSB research meets scientific and ethical standards. PIs must register the use of human, nonhuman primate, and murine stem cells with SCRO. The SCRO Coordinator is the point of contact for submittals.

Human Subjects Committee (HSC)

HSC oversees protocols involving human subjects, including cells and tissues derived from human subjects. The HSC Coordinator is available to the investigator for advice and assistance in planning the use of human subjects within federal, state, and University regulations.
