青霉素G钠 (Penicillin G Sodium),CAS号:69-57-8,分子量:356.37,效价≥1500 U/mg。本品为青霉素G钠的无菌储存液,浓度50 mg/mL,经0.22 μm滤膜过滤除菌,可直接使用。青霉素G钠属β-内酰胺类抗生素,通过抑制细菌细胞壁的合成发挥杀菌作用,对革兰阳性菌(如链球菌、葡萄球菌)及部分革兰阴性菌(如肺炎球菌)具有良好抗菌活性,广泛应用于细胞培养、微生物筛选及分子生物学等科研领域。
使用方法
1.本产品已过滤除菌,可直接使用。使用前请解冻并充分混匀,根据实验需求按比例稀释后使用。
2.建议初次使用时通过预实验确定最佳工作浓度。
注意事项
1.反复冻融易导致抗生素效价下降,建议根据单次用量分装后-20℃保存。
2.青霉素G钠对β-内酰胺酶敏感,使用过程中应避免接触青霉素酶环境。
3.本产品仅供科研使用,请勿用于临床诊断或治疗。
Penicillin G Sodium, CAS No.: 69-57-8, molecular weight: 356.37, potency ≥ 1500 U/mg. This product is a sterile stock solution of Penicillin G Sodium at a concentration of 50 mg/mL. It is sterilized by filtration through a 0.22 μm membrane filter and is ready to use. Penicillin G Sodium belongs to the β-lactam class of antibiotics and exerts a bactericidal effect by inhibiting bacterial cell wall synthesis. It has good antibacterial activity against Gram-positive bacteria (such as Streptococcus and Staphylococcus) and some Gram-negative bacteria (such as Pneumococcus), and is widely used in scientific research fields such as cell culture, microbial screening, and molecular biology.
Instructions for Use:
1.This product has been filter-sterilized and is ready to use. Before use, please thaw and mix thoroughly, and dilute proportionally according to experimental requirements.
2.For first-time use, it is recommended to determine the optimal working concentration through preliminary experiments.
Precautions:
1.Repeated freeze-thaw cycles can easily lead to a decrease in antibiotic potency. It is recommended to aliquot the product based on single-use amounts and store at -20 °C.
2.Penicillin G Sodium is sensitive to β-lactamase; avoid contact with penicillinase-containing environments during use.
3.This product is for research use only. Please do not use it for clinical diagnosis or treatment.
