Fida Biosystems
Kritika Sahni Ray, Dr. rer. nat., currently serves as a Field Application Scientist at Fida Biosystems since February 2022. Previously, Kritika held the position of Associate Scientist at Cellworks Life from May 2020 to February 2022. Kritika's academic journey includes a PhD in Natural Sciences from the University of Bonn, completed in 2019, and a Master's degree in Biochemistry from the University of Hyderabad obtained in 2015. Notably, Kritika was a PhD Researcher at Forschungszentrum Jülich from July 2015 to July 2019, where the research focused on cellular migration dynamics using human epidermal keratinocytes. An internship at SIRION BIOTECH GmbH in late 2016 involved developing lentivirus surface adapter proteins for targeted gene delivery. Earlier academic work included a Master’s thesis at the University of Hyderabad investigating the role of Calpain2 in breast gland development.
Fida Biosystems
Fida Biosystems offers a new proprietary technology developed for quantification and characterization of proteins and nanoparticles from 0.5 to 1,000 nm Dh, incl. antibodies, liposomes, exosomes, membrane embedded proteins et al. Based on accurate, in-solution, absolute measurements of hydrodynamic radius, the technology provides precise information about Kd, concentration, size, stoichiometry, conformational changes, oligomeric state, immunogenicity, multiple bindings etc. It is characterised by being fast (minutes), requiring very small sample amounts (ul-nl), and being exceptionally tolerant to the sample matrix, incl. plasma, serum, cell lysate, fermentation media etc. Contrary to most other procedures, the methodology is based on binding in homogenous solution; complications related to non-specific surface adsorption and challenging assay development are therefore avoided. I.e. the unique features of the FIDA technology enable characterisation and quantification in native (biorelevant) environments and in-built assay quality control and automation.
