Procyanidin B1
CAS No. : 20315-25-7
MCE 国际站：Procyanidin B1
产品活性：Procyanidin B1 是一种多酚类黄酮物质，存在于常见的水果中，能够与 TLR4/MD-2 复合体结合，具有抗炎活性。
作用靶点：Toll-like Receptor (TLR)
In Vitro: Procyanidin B1 is a polyphenolic flavonoid isolated from fruits and fruit juices, binds to TLR4/MD-2 complex, and has anti-inflammatory activity. Procyanidin B1 causes cellular toxicity at concentrations >100 μg/mL. Procyanidin B1 (100 μg/mL) inhibits LPS-induced TNF-α production, and expression of MD-2, TRAF6, NF-κB mRNA, phosphorylated p38 MAPK and NF-κB protein in THP1 cells. Procyanidin B1 (50-100 µM) protects against Aβ oligomer-induced neuronal death. Procyanidin B1 potently inhibits the activation of caspase-3 at 100 µM, caspase-8 at concentrations of 30, 50, and 100 µM and caspase-9 at concentrations of 10, 30, 50, and 100 µM. Procyanidin B1 (10, 20, 30 μM) significantly and dose-dependently induces expression of ACO and CPT1, with no obvious effect on mRNA expression of PPARα.

文献和实验:5-ggggggctagctactagcatgatcagggggtagtcagcgt-3 B1:5-acgctgactaccccctgatcatgctagtagctagcccccc-3 B2:5-cgttttaaaaaattatcccct-3 我们的目的是将基因A,B通过PCR的方法连接起来，我们可以仔细的观察上面的引物A2和B1，我们会发现这两条引物要比另外两条引物长很多，为什么会这 样呢？这就是我们在设计引物的时候在A2的5端加入了20个B基因5端的序列，在B1的5端加入了20个A基因3端的序列。我们来看重叠PCR的步骤
培养基、糖发酵管、ONPG培养基、半固体琼脂、丙二酸钠培养基、沙门氏菌因子血清：按26种用于初步分型；57种用于进一步分型；163种用于详细分型。4 检验程序沙门氏菌检验程序如下：5 操作步骤5.1 前增菌取检样25g，加入225mL缓冲蛋白胨水于均质杯内。用均质器以8000~10000r/min打碎1min，于36±1℃培养4h（干蛋品培养18~24h），移取10mL，转种于100mL氯化镁孔雀绿增菌液（MM）或四硫酸钠煌绿（TTB）增菌液内，于42℃培养18~24h。同时，另取10mL，转种
Assaying Cdc25 Phosphatase Activity
fluorescein diphosphate (FDP) as a substrate is recommended. To analyze endogenous Cdc25 phosphatase activities of immuno-precipitates from total cellular extracts, the physiological substrate Cdk1/cyclin B1 is most sensitive.
