Who we are and what we do

Quasar Bio is a biotechnology-based research company for the development, discovery, and validation of new solutions for chemotherapy and control of human and animal diseases.


We have a portfolio of high-tech assays based on the evaluation of phenotypic activity in cell assay models to determine efficacy and characterize the mechanism of action in the cellular microenvironment. We develop new tests on demand, being able to use chemical compounds (small molecules, natural or biological products), in addition to developing drug discovery projects and evaluating the activity of bioactive compounds.

Phenotypic Screening

Our flagship. We are a pioneer group in phenotypic screening, working with this technology for over 15 years, with techniques based on a long history of successful scientific publications, mainly dedicated to the discovery of drugs for neglected diseases such as Chagas disease, leishmaniasis, malaria, and dengue, in addition to promising discoveries of drug repositioning for emerging diseases such as the Zika virus and Chikungunya.

We are a bridge between University and Companies for the development of research and products for the benefit of society.


Partnerships for Science

Quasar Bio bridges the gap between companies and universities, linking researchers at major Brazilian universities to the latest equipment made available by partner companies Promega and Pensabio. The Promega GloMax® Explorer microplate reader equipment marks a revolution in phenotypic analysis and is available, at Quasar Bio, to any researcher who needs to carry out related experiments.

Luminescence, Fluorescence and Absorbance Reading


The Promega GloMax® Explorer microplate reader, which performs highly accurate measurements with high sensitivity, capturing from the most intense signals to the weakest ones. The same equipment performs the reading of luminescence, fluorescence and absorbance, and it is possible to work with the most diverse types of assays, from cell viability, toxicity and metabolism, kinase, cell signaling, reporter gene, nucleic acid quantification for NGS, PROTACs and protein degradation, bioassays, BRET, ELISA and even water quality tests.
