嘌呤霉素 (Puromycin, PM)是一种蛋白质合成抑制剂,CAS号为53-79-2,它具有与tRNA分子末端类似的结构,能够同氨基酸结合,代替氨酰化的tRNA同核糖体的A位点结合,并掺入到生长的肽链中。虽然嘌呤霉素能够同A位点结合,但是不能参与随后的任何反应,因而导致蛋白质合成的终止并释放出C-末端含有嘌呤霉素的不成熟的多肽。 嘌呤霉素二盐酸盐是一种由白黑链霉菌 (Streptomyces alboniger) 发酵产生的氨基核苷类抗生素,是嘌呤霉素的稳定盐酸盐形式,常被称为嘌呤霉素盐酸盐,其cas号是58-58-2。
嘌呤霉素盐酸盐溶液 (1 mg/ml)由高纯原料和甲醇配制而成,如有需要应用有机滤膜过滤后用于细胞培养。其摩尔数为1.84 mmol/L,工作浓度一般为10-100 μmol/L。本产品仅用于科研领域,不适用于临床诊断或其他用途。
操作步骤 (仅供参考):
1、根据实验具体要求操作。
2、以工作浓度为100 μmol/L为例,每10ml培养基中加入544μl 嘌呤霉素盐酸盐溶液 (1 mg/ml)。
注意事项:
1、注意无菌操作,避免污染。避免反复冻融,以免失效。
2、为了您的安全和健康,请穿实验服并戴一次性手套操作。
Puromycin (PM) is a protein synthesis inhibitor with a CAS number of 53-79-2. It has a structure similar to the terminal end of tRNA molecules, which enables it to bind to amino acids, replace aminoacylated tRNA to bind to the A-site of ribosomes, and be incorporated into the growing peptide chain. Although puromycin can bind to the A-site, it cannot participate in any subsequent reactions, thus terminating protein synthesis and releasing immature polypeptides containing puromycin at the C-terminus. Puromycin dihydrochloride is an aminonucleoside antibiotic produced by the fermentation of Streptomyces alboniger. As a stable hydrochloride form of puromycin, it is often referred to as puromycin hydrochloride, with a CAS number of 58-58-2.
Puromycin Hydrochloride Solution (1 mg/mL) is formulated with high-purity raw materials and methanol. If necessary, it should be filtered through an organic filter membrane before being used for cell culture. Its molar concentration is 1.84 mmol/L, and the general working concentration ranges from 10 to 100 μmol/L. This product is for research use only (RUO) and is not intended for clinical diagnosis or any other applications.
Operating Procedures (For Reference Only)
1. Operate in accordance with specific experimental requirements.
2. Taking a working concentration of 100 μmol/L as an example, add 544 μL of Puromycin Hydrochloride Solution (1 mg/mL) to every 10 mL of culture medium.
Precautions
1. Ensure sterile operation to avoid contamination. Minimize repeated freeze-thaw cycles to prevent reagent inactivation.
2. For your safety and health, wear a lab coat and disposable gloves during operation.
