The Office of Research Support (ORS) does not administer or oversee HOP policy 5-2011 or training related to the policy. ORS administers HOP policy 7-1210, “Promoting Objectivity in Research by Managing, Reducing or Eliminating Financial Conflicts of Interest” so if you conduct research and have:

  1. Not submitted a Financial Interest Disclosure (FID), you will need to complete mandatory training and file a FID. Instructions for completing these requirements are located at
  2. Previously submitted a FID, you are not required to complete additional training nor re-disclose the same information to comply with the UTS 180/HOP 5-2011 policy requirements.   However, you may have other responsibilities under that policy.

HOP policy 5-2011 QUESTIONS? Contact the Provost’s Office or call Mike Kerker, Associate Vice Provost at (512) 471-2694.



Human cell lines are commonly used in biomedical research, yet appropriate biosafety requirements for handling human cell lines are often subject to debate within the scientific community. In order to clarify the University's position on this matter, the Institutional Biosafety Committee (IBC) has created the following guidance. 


In 1991, the Occupational Safety and Health Administration (OSHA) issued the Bloodborne Pathogens (BBP) Standard to protect employees who have occupational exposure to human blood or other potentially infectious materials. While human blood, most body fluids, unfixed human tissues and organs were clearly included within the scope and application of the standard, the inclusion of human cell lines was ambiguous.

In 1994, OSHA issued an interpretation of the applicability of the BBP Standard towards human cell lines. According to the interpretation, human cell lines are considered to be potentially infectious and within the scope of the BBP Standard unless the specific cell line has been characterized to be free of hepatitis viruses, HIV, Epstein-Barr virus, human papilloma viruses and other recognized bloodborne pathogens. In alignment with this interpretation, the American Type Culture Collection (ATCC) recommends that all human cell lines be accorded the same level of biosafety consideration as a line known to carry HIV.  Moreover, the 5th Edition of the CDC publication, Biosafety in Microbiological and Biomedical Laboratories (BMBL),recommends that human and other primate cells should be handled using Biosafety Level 2 (BSL-2) practices and containment.

In consideration of the aforementioned regulatory interpretation and consensus guidelines and other factors, the IBC has adopted the following guidance regarding use of human cell lines.

  • Unless the researcher has documentation of screening for bloodborne pathogens, all cell and organ cultures of human/NHP origin including established cell lines shall be handled in accordance with the OSHA Bloodborne Pathogens Standard and under BSL-2 containment.   Existing and future University’s laboratory safety policies should reflect this guidance.
