Central Research Laboratory

NIMR Central Research Laboratory (CRL) and Activities
Management of the Nigerian Institute of Medical Research reactivated the Central Research Laboratory (CRL) in May 2019.

The mission is to give researchers the edge to compete with international counterparts. The aim of the CRL is to provide access to the state-of-the-art equipment, facilities and technical expertise essential for the thriving of medical research in Nigeria. The laboratory promotes scientific thinking and experimental exposure for biochemical and clinical researchers. It also provides students with hands-on experience with advanced research training. The CRL is equipped with modern equipment to service the research needs of the relevant research Departments of the Institute and the public. It intends to advance research in most health research disciplines including Biological and Clinical sciences and compliment other specialized departments of the Institute.

 

Opportunity of the NIMR CRL

NIMR expect over 200 Biomedical and Clinical Scientists as end-users of this facility. There is a high demand by students (Masters and Ph.D.) for the use of the State-of-the Art facility for research. We therefore envisage that the CRL will be self-funded through a revolving funding scheme in NIMR. Alliance with other Institutions through the facility will widen the level of collaborations between this research laboratory and other health research related institutions. It will serve as Centre of excellence for quality molecular and genomics analysis thereby reducing the huge amount of money spent on training Biomedical Research Scientists in related centres abroad. Below are list of equipment

The CRL provides research services in primer and probe design (Taqman chemistry) for realtime detection and quantitation of pathogens in biological samples as well as monitoring gene expression in cells using RTPCR Quant Studio 3(QS3). (Thermofisher Scientific USA).

In-Vitro Gen Thermofisher Scientific Flowcytometer (Serial No: 2AFC222501018)

Flow cytometry is a technology used to count and distinguish cells of different types in a mixture by quantitating their structural features. Therefore, flow cytometry has great advantages compared to traditional microscopy since it permits the analysis of a greater number of cells in a fraction of the time. Flow cytometry is routinely used in basic research, clinical practice, and clinical trials. Uses for flow cytometry include:  Cell counting  Cell sorting  Determining cell characteristics and function  Detecting microorganisms  Biomarker detection  Protein engineering detection  Diagnosis of health disorders such as blood cancers. In-Vitro Gen Thermofisher Scientific Flowcytometer also, has been installed
