Figure Lengend Snippet: Characterization of BG505 SOS.664-dPG and related Env proteins. ( A ). D7324-capture ELISA with unpurified D7324-tagged BG505 SOS.664, SOS.664-dPG, and BG505 SOSIP.664 trimers expressed in the supernatant of HEK293T cells. ( B ) Top: SEC curve of BG505 SOS.664-dPG produced in suspension 293S cells and purified using 2G12 affinity chromatography. Bottom: BN-PAGE analysis of the SEC fractions depicted above. ( C ) NS-EM analysis on 2G12/SEC-purified BG505 SOS.664-dPG.
Article Snippet: The trimers were then immobilized via their D7324 tags for 2 h at room temperature on half-well 96-well plates (Greiner) precoated with Ab D7324 (Aalto Bioreagents) at 10 μg/mL in 0.1 M NaHCO3, pH 8.6 overnight ( ).
