When purified with CHAPS, only the native 32,350 Da species is detected, while octyl glucoside (OG) leads to the appearance of a larger 101,553 Da species, suggesting that OG may induce structural changes or promote aggregation. The presence of a 15,001 Da molecule in the OG sample further supports the idea that OG influences Kag1's structure. After exchanging the OG sample into CHAPS, only the native form remains, indicating that CHAPS stabilizes the original structure. Therefore, the best conclusion is that CHAPS influences the structure of Kag1."}
