ILS develops antibodies against Chikungunya viral infection

Date: 24 June 2019 Tags: Biotechnology

Institute of Life Sciences (ILS) has successfully developed antibodies against Chikungunya viral (CHIKV) infection. These antibodies fight against the non-structural proteins - nsP1, nsP3 and nsP4 of CHIKV. The antibodies were developed following decade-long research on CHIKV infection at the ILS laboratory headed by senior molecular virologist Dr. Soma Chattopadhyay. She has been selected for Biotech Product, Process Development and Commercialisation Award 2019 by the Department of Biotechnology.
