Known as a female hormone, estrogen, has an effect on the male reproductive organs. The estrogen has to combine with the estrogen receptor to communicate a signal. Propyl pyrazole triol (PPT) is an estrogen receptor alpha selective agonist with a 410-, or 1,000-fold relative binding affinity for est...

P450 aromatase는 무엇으로 구성되어 있는가? | 생체 내 에스트로겐은 testosterone과 androstenedione이 aromatization을 통해 각각 estradiol과 estrone으로 전환되어 형성되는데, 이 과정을 중재하는 효소가 P450 mono-oxygenase 효소 복합체 이다. P450 aromatase는 CYP19 유전자의 생산물로서 최소 16개의 exon으로 구성되어 있으며, 사람의 경우 15번 염색체에 위치해 있다(O’donnell et al., 2001). | |

마이크로톰을 이용하여 2.5 μm 두께의 절편을 만들어 사진촬영을 위해 염색하는 과정은? | 5 μm 두께의 절편을 만들었다. 이 절편을 periodic acid-Schiff (PAS)와 hematoxylin으로 이중 염색을 실시하였다. 이 염색과정은, 먼저 조직 절편을 다음 순서대로 증류수에 10분, periodic acid에 15분, 증류수에 10분, Schiff용액에 45분, sulfurous acid에 3회씩 각각 5분, 흐르는 물에 20분, hematoxylin에 35분, 그리고 마지막으로 흐르는 물에 10분을 두었다가 꺼낸 다음 35°C의 slide warmer 에서 절편을 건조시킨 다음 Permount로 봉입하여 프레파라트를 완성하였다. |
