Title: Multiplexed Nucleic Acid Programmable Protein Arrays Document date: 2017_9_20
ID: 7t1o19kn_7
Snippet: We first demonstrate that multiplexed proteins are displayed on M-NAPPA using protein-specific antibodies. Second, we compare the ability of M-NAPPA with non-multiplexed NAPPA to detect different protein-protein interactions and the serological antibody reactivity against 646 viral proteins. Next, we show the feasibility of M-NAPPA in performing high throughput screening for immune-dominant tuberculosis (TB) antigens through the use of an ultra-h.....
Document: We first demonstrate that multiplexed proteins are displayed on M-NAPPA using protein-specific antibodies. Second, we compare the ability of M-NAPPA with non-multiplexed NAPPA to detect different protein-protein interactions and the serological antibody reactivity against 646 viral proteins. Next, we show the feasibility of M-NAPPA in performing high throughput screening for immune-dominant tuberculosis (TB) antigens through the use of an ultra-high density M-NAPPA TB proteome array containing four subarrays with 4,045 TB open reading frames (ORFs) on one slide. Using M-NAPPA TB protein microarrays, four new immune-dominant antigens in the sera of BCG-vaccinated guinea pigs were identified, which were then validated using ELISA. Finally, we propose a high throughput target discovery and verification pipeline based on the M-NAPPA approach.
