英文别名 | Chloromycetin® D-threo-2,2-Dichloro-N-[β-hydroxy-α-(hydroxymethyl)-4-nitrophenethyl]acetamide D-(−)-threo-2,2-Dichloro-N-[β-hydroxy-α-(hydroxymethyl)-β-(4-nitrophenyl)ethyl]acetamide D-(−)-threo-2-Dichloroacetamido-1-(4-nitrophenyl)-1,3-propanediol;2,2-Di |
应用 | 在转肽酶(peptidyl transferase)步骤抑制在50S 核糖体亚单元上的翻译。 |
规格或纯度 | 98% |
运输条件 | 超低温冰袋运输 |
生化机理 | Mode of Action: Chloramphenicol inhibits bacterial protein synthesis by blocking the peptidyl transferase step by binding to the 50S ribosomal subunit and preventing attachment of aminoacyl tRNA to the ribosome. It also inhibits mitochondrial and chloroplast protein synthesis and ribosomal formation of (p)ppGpp, de-pressing rRNA transcription. Mode of Resistance: Use of chloramphenicol acetyltransferase will acetylate the product and inactivate it. Antimicrobial Spectrum: This is a broad spectrum antibiotic against gram-positive and gram-negative bacteria, and is used mainly for ophthalmic and veterinary purposes. |

产品介绍:
Chloramphenicol 是一种 (bacterial) 感染的广谱抗生素,作为细菌蛋白质生物合成的有效抑制剂。Chloramphenicol 主要作用于细菌 70S 核糖体的 50S 亚基,通过抑制肽基转移酶活性来抑制肽键的形成。
application:
Chloramphenicol is a synthetic antibiotic, isolated from strains of Streptomyces venezuelae. It is often used for bacterial selection in molecular biology applications at 10-20 μg/mL and as a selection agent for transformed cells containing chloramphenicol reistance genes.
