其他说明

仅用于生命科学研究。不可用于诊断。 Solution, 50 mg/ml, in PBS (phosphate-buffered saline), filtered through 0.2 μm pore size membrane.

制备说明

Working concentration: Recommended concentration for the selection of resistant cells is 50 to 1000 μg/ml in cell culture. A commonly used concentration for the selection of mammalian cells is 200 μg/ml. However, the optimal concentration must be determined experimentally, and may vary with the type of cell used.

General Description

Formula: C 20 H 37 N 3 O 13 LD50: 6 mg/kg in mouse (i.v.);13 mg/kg in guinea pig (i.p.); 63 mg/kg in rat (i.p.) Molecular weight: Mr = 527.5 Working concentration: 50 – 1,000 μg/ml in cell culture. A commonly used concentration for the selection of mammalian cells is 200 μg/ml. However, the optimal concentration must be experimentally determined, since it may vary depending on the type of cell used.

Application

Hygromycin B is an aminoglycosidic antibiotic that inhibits protein synthesis in prokaryotes and eukaryotes. It is used to select and maintain the phenotype of eukaryotic cells that are stably transfected with the E. coli hygromycin-resistance gene (hyg or hph).

Other Notes

For life science research only. Not for use in diagnostic procedures. Solution, 50 mg/ml, in PBS (phosphate-buffered saline), filtered through 0.2 μm pore size membrane.

潮霉素 B 来源于吸水链霉菌

一般描述

化学结构：氨基糖苷类 氨基糖苷是靶向核糖体的最广泛使用的一类抗生素。潮霉素B是一种氨基环醇抗生素。 吸水链霉菌 具有磷酸转移酶（HPH）活性，可将潮霉素B磷酸化，从而有助于激活针对该药物毒性作用的自身免疫。

应用

潮霉素B是一种氨基糖苷类抗生素，分离子从 吸水链霉菌。 它已被用于研究70S核糖体易位和mRNA模板误读水平的蛋白质合成；作为一种抗病毒剂，通过选择性穿透被病毒感染渗透的细胞并抑制翻译；以及作为潮霉素抗性基因转化细胞的选择剂。 建议以100-800 μg/mL的浓度用作选择剂，其中对于原核生物使用100 μg/mL，对于低等真核生物使用200 μg/mL，对于高等真核生物使用150-400 μg/mL。 潮霉素B抗生素可用于以下细胞的抗潮性作用： 160 μg/ml，用于经质粒混合物转染的293T细胞。 150 g/ml，用于MCF-7 ALOX12 细胞。 MSCV荧光素酶PGK-hygro质粒。 STAT3报告基因HeLa稳定细胞系（通过受STAT3启动子控制的荧光素酶基因稳定转染），维持在补充有10％FBS的DMEM中。

制备说明

该产物通过离子交换色谱法进行纯化。 潮霉素B可以>50 mg/mL的浓度溶于水，也可溶于甲醇或乙醇。 溶液应通过过滤而非高压灭菌进行灭菌。 另外，据报道潮霉素B溶液在冷冻时会失去活性，并且其在冷藏可保持稳定，因此应避免冷冻。

General Description

Chemical structure: aminoglycoside Aminoglycosides are the most widely used class of antibiotics that target ribosome. Hygromycin B is an aminocyclitol antibiotic. The organism, S. hygroscopicus contains phosphotransferase (HPH) activity, which phosphorylates hygromycin B helping in autoimmunity against the toxic effects of the drug.

Application

Hygromycin B antibiotic was used for hygro resistance effect in the following cells: transfected 293T cells with mixture of plasmids at 160 μg/ml. MCF-7 ALOX12 cells at 150 μg/ml. MSCV Luciferase PGK-hygro plasmid. STAT3 Reporter HeLa Stable Cell Line (stably transfected with Luciferase gene under the control of STAT3 promoter) maintained in DMEM supplemented with 10% FBS. Hygromycin B is an aminoglycoside antibiotic isolated from Streptomyces hygroscopicus. It has been used to study protein synthesis at the level of the 70S ribosome translocation and mRNA template misreading, as an antiviral agent by selectively penetrating cells rendered permeable by virus infection and inhibiting translation, and as a selection agent for hygromycin resistance gene transformed cells. It is recommended for use as a selection agent at 100-800 μg/mL, specifically at 100 μg/mL for prokaryotes, 200 μg/mL for lower eukaryotes and 150-400 μg/mL for higher eukaryotes.
