초록

아포리포포린-III (apoLp-III)를 꿀벌부채명나방 종령 유충 혈림프에서 KBr 농도구배 초원심분리와 겔크로마토그래피 (Sephadex G-100)를 이용하여 분리, 정제하였다. 본 연구에서는 아포리포포린-III가 꿀벌부채명나방의 종령 유충 지방체에 의해 흡수되는 지를 조사하였다. 종령 유충 지방체 조직을 FITC로 표지한 아포리포포린-III(FITC-apoLp-III)와 상온에서 30분간 배양하였다. 배양 후 형광현미경과 전기영동을 이용하여 FITC-apoLp-III가 지방체 조직으로 들어가는 지의 여부를 확인하였다. 그 결과 FITC-apoLp-III가 유충 지방체로 흡수된다는 사실을 알 수 있었다.

Apolipophorin-III (apoLp-III) was isolated and purified from the last larval hemolymph of Galleria mellonella by the KBr gradient ultracentrifugation and gel chromatography (Sephadex G-100). In this paper, we examined that apoLp-III is taken up into the last larval fat bodies in Galleria mellonella. The last larval fat body tissues were incubated at room temperature for 30 min with fluorescein isothiocyanate (FITC)-labeled apoLp-III (FITC-apoLp-III). Fluorescein microscopy and sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis (PAGE) revealed that the last larval fat body tissues internalize FITC-apoLp-III. The results show that the apoLp-III is taken up by the last larval fat body.
