| | SPR Method for Detecting Affinity of Compounds Disclosed Herein for KRAS Protein Subtype G12D or WT |
| Description: | Biotinylated Avi-KRAS-WT or Avi-KRAS-G12D was diluted to 20 μg/mL with 1x HBS-P+(Cat. #BR1006-71) buffer containing 100 mM MgCl2, and then flowed through SA (Cat. #BR1005-31) biosensing chip channel 2 for 420 s to obtain a coupling level of approximately 5000-7000 RU. Then samples of small molecular compounds were injected for 120 s in an ascending order, and then were dissociated for 720 s. The experiment employed a single-cycle kinetic mode. Reaction signals were detected in real time using a Biacore 8K instrument to obtain association and dissociation curves. After the experiment ended, data analysis was performed using Biacore 8K evaluation software, and affinity data were obtained by performing data fitting using a 1:1 model. |
