Welcome to ChABSA

ChABSA, the Chesapeake Area Biological Safety Association, is an incorporated, non-profit organization that is an affiliate of the American Biological Safety Association (ABSA) established in 1984. ChABSA was established in 1987 by local area members of ABSA with a similar interest in the safety of research using microorganisms and recombinant DNA.

Kevin Holmes, Ph.D. ofNIAID, NIHWill Present on:

Cell Sorting Biosafety:

Current Practices

Cell Sorting has become an invaluable resource to a wide variety of research programs because it enables the rapid purification of well-defined cell subsets for further experimental manipulation.  Modern high speed cell sorters by design produce defined droplets by forcing cells under high pressure,  through a small diameter nozzle, but may produce high concentrations of aerosols in the event of a partial nozzle obstruction.  Therefore, cell sorters are considered a laboratory procedure hazard, due the potential for aerosol production.  The flow cytometry community has been active in the development of biosafety Standards for cell sorters.  An overview of these Standards as well as their practical applications will be presented with the goal to provide a better understanding of the biosafety aspects of this technology.



Dr. Kevin Holmes received his Ph.D. degree in Human Anatomy from the Medical College of Virginia in 1981, where his thesis was in developmental immunology. Following post-doctoral fellowships studying hematopoietic development and retroviral induced leukemias and lymphomas, Dr. Holmes was made head of the newly formed Flow Cytometry Section in 1987. The mission of the Flow Cytometry Section (FCS) is to provide the NIAID Intramural Research Program with application-specific flow cytometric technologies, including instrumentation for high speed cell sorting and multi-color analysis and to provide training, consultation and method development for experiments involving flow cytometry. The FCS consists of eight FACS Aria III cell sorters and seven analyzers, and includes two cell sorters housed in BSL3 laboratories.


Dr. Holmes is a member of the NIH IBC and chair of the NIH Occupational Health and Safety Committee. Dr. Holmes is chair of the International Society for the Advancement of Cytometry (ISAC) Biosafety committee and co-chaired an NIH Task force to develop the NIH Biosafety Policy for Cell Sorters.  He was first author on the newly revised ISAC Cell Sorter Biosafety Standards and has also authored book chapters on cell sorter biosafety.
