Bioassay Laboratory

Under the Translational Research Program, we are establishing a bioassay laboratory for the clinical development of vaccines and biologicals. The bioassay laboratory is intended to meet the global standards in Good Clinical Laboratory Practice (GCLP) and will be applying for accreditation by National Accreditation Board for testing and calibration Laboratories (NABL) for vaccine development and testing.

As part of our phase I activities, a laboratory measuring around 2000 sq. ft. has been set up as per the guidelines of WHO and NABL. Eight separate rooms have been created to maintain unidirectional workflow and segregate the activities such as flow cytometry, serology, reagent preparation, nucleic acid isolation, template addition, PCR and post-PCR rooms and animal cell culture for virus cultivation. All the equipment has been calibrated and validated as per the NABL requirements.
