도면에서,
도 1a~도 1c는 PS20, PS80, 및 F68이 다음의 테스트 조건 하에서 ExPEC 글리코콘쥬게이트의 냉동/해동 유도된 응집을 방지할 수 있지만 소르비톨은 상기 응집을 방지할 수 없음을 나타낸다: PS20, PS80, F68 및 소르비톨을 ExPEC 글리코콘쥬게이트 제형에 첨가하고, 냉동/해동 유도된 스트레스를 가하였다.
도 1a는 크기 배제 크로마토그래피-고성능 액체 크로마토그래피(SEC-HPLC) 크로마토그램의 적분법을 나타낸다.
도 1b는 냉동/해동 전후의 실험의 결과를 보여주는 SEC-HPLC 크로마토그램을 나타낸다.
도 1c는 전체 피크 적분시 프리피크(pre-peak) 1의 백분율 값을 도시한 그래프를 나타낸다.
도 2는 12주의 장기간 동안 40oC를 가할 때 제형 26 및 제형 28의 SEC-HPLC 크로마토그래피 프리피크 1의 백분율을 종래의 ExPEC 글리코콘쥬게이트 제형과 직접(head-to-head) 비교하는 그래프를 나타낸다: 직립(↑) 및 역(↓) 바이알 배향 둘 다를 조사하였으며, 제형 26 및 제형 28은 열적 스트레스(40℃)를 가할 때 종래의 ExPEC 글리코콘쥬게이트 제형에 비하여 증가된 안정성을 보여주었다.
도 3은 3가지의 상이한 농도의 텅스텐 추출물(HW, MW, LW)에 노출시키고 40℃에서 4주 동안 보관할 때 종래의 ExPEC 글리코콘쥬게이트 제형과 비교하여 제형 26 및 제형 28의 프리피크 1의 동향을 보여주는 그래프를 나타낸다.
도 4는 PETG 및 PC 플라스틱 물질과 접촉하고 있는 종래의 제형과 비교하여 제형 26 및 제형 28의 교반 스트레스 전후의 실험 결과를 보여주는 SEC-HPLC 크로마토그램을 나타낸다(T0은 대조구, 즉, 교반 스트레스가 없는 것임).
