Development of a Liposome-Based Serological Assay for SARS-CoV-2 Variants with Special Emphasis on Coupling Chemistries Required to Maintain Protein Antigenicity

5 Sept 2025

Abstract excerpt

The conjugation of proteins to the outer membranes of liposomes is a standard procedure used in bioanalytical and drug delivery approaches. Herein, we describe the development of a liposome-based surrogate assay for the quantification of SARS-CoV-2 neutralizing antibodies. Taking into consideration differences in amino acid sequences within the receptor-binding domain (RBD) of SARS-CoV-2 Spike proteins derived...
