HA Peptide | MedChemExpress (MCE)

HA Peptide 产品活性：HA Peptide (HA tag) 是来自人类流感血凝素 (HA) 的由九个氨基酸组成的多肽。HA Peptide 广泛用于细胞生物学和生物化学中分离，纯化，检测和追踪目标蛋白。 产品来源： https://www.medchemexpress.cn/HA_Peptide.html 研究领域：Anti-infection 作用靶点：Influenza Virus 结构分类：其他类 In Vitro: HA Peptide is a highly immunoreactive tag generally used for the separation of tagged proteins from cell culture supernatants and cell lysate under neutral pH conditions and thus are handy tools for coimmunoprecipitation but are also easily detected via western blot. HA Peptide is small and thus unlikely to interfere with the bioactivity and function of the fusion partner proteins. HA Peptide comes from human influenza hemagglutinin (HA) corresponding to amino acids 98–106 and is a strong immunoreactive epitope making it popular to isolate, purify, detect, and track the protein of interest. The recombinant HA-tagged proteins can be separated by highly specific anti-HA monoclonal antibody that is covalently immobilized on resin. The HA-tagged proteins can be eluted by mild elution approach with HA epitope at 1 mg/mL in TBS. On the other hand, three chemical elution options are available: 0.1 M glycine (pH 2-2.8), 3 M NaSCN, or 50 mM NaOH. The nucleotide sequences encoding an N-terminal HA Peptide in the mammalian expression vectors is an essential element for the T7 promoter-driven expression in E. coli even without trans-acting T7 RNAP. Research results suggest that HA Peptide is cleaved by caspase 3/7, and HA Peptide cleavage results in a total loss of immunoreactivity. Observations indicate that the use of HA to tag proteins and constructs to study cell death–related and apoptotic mechanisms can result in serious artifacts. 相关产品：Natural Product Library Plus | Bioactive Compound Library Plus | Acetylcysteine | Tunicamycin | Curcumin | U0126-EtOH | Camptothecin | Vadimezan | Indomethacin | Aprotinin | Rifampicin | Molnupiravir | Baicalein | Oseltamivir acid | Spermine | Geldanamycin | AEBSF hydrochloride | α-Vitamin E | Favipiravir | Chlorogenic acid | 6-Diazo-5-oxo-L-nor-Leucine | Baloxavir | Tofacitinib citrate | Trimethoprim | AG-1478 | Harringtonine | YM-201636 | Isoliquiritigenin | SC75741 | GSK 650394 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。
