Figure Lengend Snippet: Fig. 5. Milligram Scale CHT Chromatography and Corresponding HPSEC Profile for SARS-CoV-2 Spike Protein RBD. 5A shows the chromatography profile of SARS- CoV-2 Spike Protein RBD from the CHT resin. Flow through, wash, and strip peaks were observed. 5B, 5C, 5D, and 5E respectively show the flow through, wash 1, wash 2, and strip HPSEC purity profiles. UV A280, conductivity, and pH traces are respectively shown in blue, orange, and purple.

Article Snippet: Development of a scalable aggregate removal operation to replace the SEC operation consisted of studying the behavior of SARS-CoV-2 Spike Protein RBD from the Wuhan strain on CHT Type II resin (BIORAD; Hercules, CA, USA) resin (1.6 cm column diameter, 14.8 cm bed height).

Figure Lengend Snippet: Fig. 8. SDS-PAGE and Western blot Analyses of Gram Scale SARS-CoV-2 Spike Protein RBD. The CHT Type II gram scale product was analyzed by SDS-PAGE in 8A and Western blot in 8B. The milligram control and CHT Flow Through Products were visualized by reaction with a biotinylated polyclonal antibody specific for the poly-histidine tag prior to application of a streptavidin labeled peroxidase. Extraneous lanes were removed from the image.
