Application

四环素是一种广谱聚酮类抗生素,在临床上用于治疗细菌感染,例如落基山斑疹热、斑疹伤寒、蜱热、Q 热和 Brill-Zinsser 疾病,并用于治疗上呼吸道感染和痤疮。 它已用于多药耐药性和包括急性胰腺炎在内的潜在副作用的研究。 细胞培养使用浓度推荐为10 mg/L。

Biochem/physiol Actions

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。

Disclaimer

该产品应在 0°C 以下冷冻,并避光和防潮。 研究表明,在这些条件下该产品可保持活性 4 年。 储备溶液应储存于 -20°C,并在 37°C 下可稳定保存 4 天。

General description

化学结构:四环素

Other Notes

保存于密闭容器内,置于干燥通风处。置于干燥处保存。

Preparation Note

该产品易溶于水,微溶于96%乙醇,几乎不溶于丙酮。 四环素被碱金属氢氧化物溶液迅速破坏,并且由于水解和沉淀,静水溶液变得混浊。 在 pH 低于 2 的溶液中四环素的效力降低。

Misfolded proteins in the endoplasmic reticulum (ER) are degraded by ER-associated degradation (ERAD). Although ERAD components involved in degradation of luminal substrates are well characterized, much less is known about quality control of membrane proteins. Here, we analyzed the degradation

Genetic perturbations that affect bacterial resistance to antibiotics have been characterized genome-wide, but how do such perturbations interact with subsequent evolutionary adaptation to the drug? Here, we show that strong epistasis between resistance mutations and systematically identified genes can be

We used BioID, a proximity-dependent biotinylation assay with 100 mitochondrial baits from all mitochondrial sub-compartments, to create a high-resolution human mitochondrial proximity interaction network. We identified 1,465 proteins, producing 15,626 unique high-confidence proximity interactions. Of these, 528 proteins were previously
