Product Introduction
Bioactivity
| 名称 | Pregnanediol |
| 描述 | Pregnanediol (5Beta-Pregnane-3Alpha,20alpha-Diol) is an inactive metabolite of PROGESTERONE by reduction at C5, C3, and C20 position. Pregnanediol(5Beta-Pregnane-3Alpha,20alpha-Diol) has two hydroxyl groups, at 3-alpha and 20-alpha. It is detectable in URINE after OVULATION and is found in great quantities in the pregnancy urine. |
| 激酶实验 | Gelatin (0.1% (w/v) is added to standard LaemmLi acrylamide polymerization mixture. Tissue extract is mixed 1:2 with sample buffer [250 mM Tris-Cl pH 6.8, 10% (w/v) SDS, 20% (v/v) glycerol, 0.005% (w/v) bromphenol blue]. Serum is diluted 1:10 with electrophoresis buffer (2.5 mM Tris, 20 mM glycine, 0.005% SDS) and mixed 1:2 with sample buffer. Twenty μLs are loaded after 10-min incubation at room temperature without boiling. After electrophoresis at 90 V, the gels are soaked in 2.5% (w/v) Triton X-100, incubated 2 to 3 days at 37°C in gelatin digestion buffer [50 mM Tris-Cl, pH 8.0, 8 mM CaCl2, 10 mM ZnSO2, 0.02% (w/v) NaN3], stained in 0.05% Coomassie blue R-250 in acetic acid/methanol/water (1:4.5:4.5 by volume), destained in 10% acetic acid and 5% methanol, and scanned for lysis band intensity. The lysis band intensity is proportional to gelatinase activity and is quantified densitometrically by using One-Dimensional Scan software. The result, a number between 0.07 and 3.75, is normalized to the protein content by dividing the densitometry result with the relative optical density from the BCA protein assay kit result. The result is used for the analysis as the arbitrary unit. For the total MMP activity results of lysis bands of pro-MMP-9, active MMP-9, pro-MMP-2, and active MMP-2 are added. A protein size marker is used to determine the correct size. |

正常有些激素是肝脏内破坏的（称为肝脏对激素的灭能作用），例如雌激素、抗利尿激素、醛固酮等。 雌激素在体内降解主要是在肝内进行，雌激素在羟化酶作用下，生成雌三醇，孕酮被还原为孕二醇。雌三醇和孕二醇在肝内与葡萄糖醛酸或硫酸盐结合，随胆汁和尿排出。动物实验及人体研究证明，肝脏受损害后，对激素的灭能作用减退，使体内及尿内的雌激素含量增加。有些肝病，（如门脉性肝硬化）患者，血与尿中的雌激素都增加，并出现蛛蜘痣（皮肤上以小动脉为中心及其向周围放射状毛细血管组成的一种小血管扩张现象）、肝掌（手掌充血发红
