LAH4 产品活性：LAH4 是两亲性肽抗生素的 α 螺旋，具有强大的抗菌 (antimicrobial)、核酸转染(nucleic acid transfection) 和细胞渗透活性。LAH4 具有较高的质粒 DNA 传递能力。LAH4 对细菌膜外膜中的阴离子脂质有很强的亲和力。 产品来源： https://www.medchemexpress.cn/LAH4.html 研究领域：Anti-infection 作用靶点：Bacterial In Vitro: LAH4 is capable of complexing DNA, associating with the cell surfacemembrane and then, when enveloped within an endosome, disrupts the endosomal membrane as the pH drops. LAH4 possesses robust plasmid DNA transfection properties. Peptides of the LAH4 family are able to efficiently deliver siRNAs in vitro into a human cell line. LAH4 is found to mediate the intracellular delivery of both protein and nucleotide cargo and facilitate protein internalization using mechanisms involving endosomal acidification and processing through the proteasome pathway, leading to enhanced cross presentation of protein antigen by dendritic cells to CD8+ T cells. LAH4 also improves the internalization of CpG, resulting in NF-kB activation, thus potentiating the adjuvant effect of CpG. LAH4 exhibits antibiotic activities against Escherichia coli and Bacillus subtilis. the peptide does not, however, lyse human red blood cells at bacteriocidal concentrations. The antibiotic activities of LAH4 are 2 orders of magnitude more pronounced at pH 5 when compared with pH 7.5. 相关产品：Rapamycin | Doxorubicin hydrochloride | Bafilomycin A1 | Dimethyl sulfoxide | Dexamethasone | Puromycin dihydrochloride | Staurosporine | Actinomycin D | Etoposide | G-418 disulfate | Nigericin sodium salt | 5-Azacytidine | Brefeldin A | CCCP | Estradiol | Ionomycin | Hygromycin B | Mitomycin C | Resveratrol | Tunicamycin | Everolimus | Doxycycline hyclate | Tacrolimus | Methotrexate | Streptozotocin | Lactate sodium | Neomycin sulfate | Acetaminophen | Anisomycin 品牌介绍: MCE (MedChemExpress) 拥有数百种全球独家化合物，我们致力于为全球科研客户提供最新最全的高品质小分子活性化合物；10,000 多种高选择性抑制剂、激动剂涉及各热门信号通路及疾病领域；设有专业的实验中心和严格的质控、验证体系；提供 LC/MS、NMR、HPLC、手性分析、元素分析等各项质检报告，确保产品的高纯度、高品质；产品的生物活性多经各国客户实验验证；Nature, Cell, Science 等多种顶级期刊及制药专利收录了MCE客户的科研成果；专业团队跟踪最新的制药及生命科学研究进展，为您提供全球最新的活性化合物；与世界各大制药公司及知名科研机构建立了长期的合作。
