High-throughput analysis of sera from ASFV-infected pigs using a proteome microarray. (a) Timelines of animal treatment and sample collection. Group A pigs ( n = 5) were infected with a virulent ASFV CN/GS 2018 strain at 1 HAD 50 . Three pigs died by 15 dpi, while the other two pigs developed clinical symptoms of ASF during the observation period but ultimately survived. Serum samples were collected at 3, 5, 7, 9, and 15 dpi. Group B pigs ( n = 5) inoculated with 10 4 HAD 50 of ASFV-GS-ΔMGF360-18R/DP71L/DP96R survived the 17-day observation period and remained alive after being challenged with 10 2 HAD 50 of the parental virus during the 13-day observation period. Serum samples were collected at 0, 7, 13, and 17 dpi and at 7 dpc. Group C pigs inoculated with 10 4 HAD 50 of ASFV-GS-ΔMGF110/360-9L ( n = 6) survived the 17-day observation period and remained alive after being challenged with 10 2 HAD 50 of the parental virus during the 13-day observation period. Serum samples were collected at 7, 13, and 17 dpi and 7 dpc. (b) Uniform manifold approximation and projection (UMAP) of the 160-ASFV-protein-specific IgG signals in the serum samples from the three groups. Each point represents an individual serum sample. (c) The amounts of the IgG-positive ASFV proteins and the shared portion from groups B and C.

Article Snippet: Gold-coated GC-FP biosensor chips were fabricated as described previously., GC-FP chips were printed with an array of 400-μm diameter spots of target and control antigens/proteins using an ArrayIt SpotBot II microarray printer. .. Proteins/antigens were first diluted to 500 μg/mL in PBS and then further diluted 1:1 just prior to printing with GBL protein array printing buffer (Grace Bio-Labs, Bend, OR). ..

Article Title: Multiplexed Detection and Quantification of Human Antibody Response to COVID-19 Infection Using a Plasmon Enhanced Biosensor Platform
Article Snippet: Double-sided adhesive gaskets and acrylic or polycarbonate fluidic covers for the GC-FP biosensor chips were either fabricated at SUNY Polytechnic Institute or obtained from Ciencia, Inc. For use in the COVID-19 detection assay, GC-FP chips were printed with an array of approximately 400 μm diameter spots of target and control antigens/proteins using an ArrayIt SpotBot II microarray printer. .. All printed proteins/antigens were first diluted to 500 μg/μl in phosphate buffered saline (PBS) and then further diluted 1:1 just prior to printing with GBL protein array printing buffer (Grace Bio-Labs) All proteins/antigens used for printing were kept at –20 °C at 500 μg/μl for long-term storage. ..

High-throughput analysis of sera from ASFV-infected pigs using a proteome microarray. (a) Timelines of animal treatment and sample collection. Group A pigs ( n = 5) were infected with a virulent ASFV CN/GS 2018 strain at 1 HAD 50 . Three pigs died by 15 dpi, while the other two pigs developed clinical symptoms of ASF during the observation period but ultimately survived. Serum samples were collected at 3, 5, 7, 9, and 15 dpi. Group B pigs ( n = 5) inoculated with 10 4 HAD 50 of ASFV-GS-ΔMGF360-18R/DP71L/DP96R survived the 17-day observation period and remained alive after being challenged with 10 2 HAD 50 of the parental virus during the 13-day observation period. Serum samples were collected at 0, 7, 13, and 17 dpi and at 7 dpc. Group C pigs inoculated with 10 4 HAD 50 of ASFV-GS-ΔMGF110/360-9L ( n = 6) survived the 17-day observation period and remained alive after being challenged with 10 2 HAD 50 of the parental virus during the 13-day observation period. Serum samples were collected at 7, 13, and 17 dpi and 7 dpc. (b) Uniform manifold approximation and projection (UMAP) of the 160-ASFV-protein-specific IgG signals in the serum samples from the three groups. Each point represents an individual serum sample. (c) The amounts of the IgG-positive ASFV proteins and the shared portion from groups B and C.
