Bio-repository Unit

Unit Head
Ozumba Petronilla Jean


The Bio-repository unit, operating under Clinical Laboratory Services Department of Institute of Human Virology, Nigeria (IHVN) was created in 2009. This unit oversees the activities at a network of biorepositories at sites with the most research activities (Abuja, Jos and Zaria) and functions to promote safe handling, receipt, processing, storage, inventory control, packaging and distribution of biological specimens, tissues and isolates (TB) with the goals of supporting IHVN research activity, public health evaluation studies, clinical trials and HIV associated malignant studies. It has the capacity to support other investigators and programs outside those of IHVN. The central bio-repository in Abuja has been awarded an NIH funded Human Heredity and Health in Africa (H3Africa) biorepositories grant (Principal Investigator: Prof. Alash'le Abimiku) to upgrade its infrastructure and functions to international standard to support H3Africa investigators in Africa and eventually expand to other investigators as well. IHVN other two biorepositories continue to support the program and research facilities of IHVN and have benefitted from the upgrade of the central biorepository. Samples from other sites are shipped to any of the 3 sites for long-term storage. The facilities have been designed using state of the art Freezer Works electronic software for the management of stored samples and power back ups to ensure an uninterrupted supply of electricity. There are plans to establish liquid nitrogen capability to support the storage of viable cells and tissues.


All three bio-repository facilities:

  1. Can support long or short term storage of serum, plasma, saliva, DNA, RNA, swabs etc. that require -20 or -80 storage: the bio-repository at the National Tuberculosis and Leprosy Tuberculosis and Leprosy Training Center (NTBLTC) supports the storage of TB isolates and other Mycobacterium.
  2. Can support processing of specimen.
  3. Can support incoming and outgoing shipments (dry ice machines, shipping supplies, and liquid nitrogen shippers).
  4. Can support efficient management and tracking of specimen through robust bioinformatics system, Freezerworks.
  5. Can contain equipment such as water distillers, autoclaves, biological safety hoods, flammable storage cabinets, solvent storage cabinets, and centrifuges (refrigerated and non-refrigerated), FASCalibur, MagNA Pure and Light cycler for DNA extraction and processing for gene detection and quantification, and tissue processing equipment.
