一般說明
化学结构：四环素
生化／生理作用
作用机制：四环素通过细胞膜中的 proin 通道被动扩散，与 30S 核糖体结合，并通过阻止氨酰基 tRNA 进入 mRNA-核糖体复合物上的受体位点来抑制蛋白质合成。它也与细菌的 50S 核糖体亚基结合，改变膜并导致细胞内成分从细菌细胞中泄漏。通过洗涤可以逆转抑制作用，这表明起到抗菌作用的是可逆结合的抗生素，而不是不可逆结合的药物。
耐药性机制：这种作用通过细胞壁通透性的丧失而失活。
抗菌谱：包括对革兰氏阳性和革兰氏阴性细菌的广泛抗菌活性。

The myeloid translocation gene 16 (MTG16) co-repressor down regulates expression of multiple glycolytic genes, which are targets of the hypoxia-inducible factor 1 (HIF1) heterodimer transcription factor that is composed of oxygen-regulated labile HIF1α and stable HIF1β subunits. For this reason

devo fare lo stock della tetraciclina. come e in cosa la devo diluire?
1 answer-
This product is soluble in methanol or ethanol, giving a completely clear solution at up to 30 mg/ml. The stability of this material in solution is pH-dependent. Stock solutions prepared in ethanol are estimated to be stable for 1-3 months when aliquoted and stored at -20°C. Please see the link below to review the product datasheet for T3258, an identical tetracycline product of another brand. The information provided applies to both products.
