一般說明

Chemical structure: aminoglycoside

應用

Gentamicin sulfate, a broad-spectrum antibiotic, used as a selection agent (gentamicin-resistance gene) in cell culture and molecular biology applications. This product is recommended for use at 50 mg/L.

生化／生理作用

作用机制：庆大大霉素通过和30S核糖亚基结合，引起密码子误读，阻碍肽酰转移酶从供体位点转移到受体位点。庆大霉素通过它与外膜的结合来发挥它对铜绿假单胞菌的杀菌作用，它在外膜上置换天然阳离子，使膜不稳定，并在细胞表面形成孔。

抗菌谱：包括革兰氏阴性和革兰氏阳性细菌，包括对于四环素、氯霉素、卡那霉素和粘菌素，某些特定假单胞菌菌株，变形杆菌属，Staphylococcus 和 Streptococcus 的抗性。

成分

Gentamicin is an aminoglycoside complex produced by fermentation of Micromonospora purpurea or M. echinospora. It is used as the sulfate salt. There are three components, each consisting of five basic nitrogens and requiresing five equivalents of sulfuric acid per mole of gentamicin base.

注意

Sterile solutions should be stored at 2-8°C. Solutions have also been shown to be stable at room temperature and in boiling aqueous buffers of pH 2-142.

MAPKs are crucial for TNF-alpha and IL-6 production by innate immune cells in response to TLR ligands. MAPK phosphatase 1 (Mkp-1) deactivates p38 and JNK, abrogating the inflammatory response. We have previously demonstrated that Mkp-1(-/-) mice exhibit exacerbated inflammatory cytokine

Inner ear sensory hair cell death is observed in the majority of hearing and balance disorders, affecting the health of more than 600 million people worldwide. While normal aging is the single greatest contributor, exposure to environmental toxins and therapeutic

Cell death pathways regulate various homeostatic processes. Autoimmune lymphoproliferative syndrome (ALPS) in humans and lymphoproliferative (LPR) disease in mice result from abrogated CD95-induced apoptosis. Because caspase-8 mediates CD95 signaling, we applied genetic approaches to dissect the roles of caspase-8 in

The reaction of 1-adamantyl isothiocyanate 4 with the various cyclic secondary amines yielded the corresponding N-(1-adamantyl)carbothioamides 5a-e, 6, 7, 8a-c and 9. Similarly, the reaction of 4 with piperazine and trans-2,5-dimethylpiperazine in 2:1 molar ratio yielded the corresponding N,N'-bis(1-adamantyl)piperazine-1,4-dicarbothioamides 10a

The molecular distinctions between mortality stages 1 (M1; senescence) and 2 (M2; crisis) of human replicative aging are ill defined. We demonstrate a qualitative difference between telomeric end associations at M1 and the end fusions that produce dicentric chromosomes and
