The properties of the additional tag facilitate identification and provide a one-step purification procedure of the fusion protein by passing cell extracts or supernatants through columns of an appropriate matrix. FLAG peptide allows elution under non-denaturing conditions. Several antibodies against FLAG peptide have been developed. One antibody, M1, binds the peptide in the presence of bivalent metal cations, preferably Ca2+. Elution is effected by chelating agents. Another strategy is competitive elution with excess of free FLAGe peptide. Antibodies M2 and M5 are applied in this procedure. The Flag-tag is first described as a calcium-dependent epitope of a monoclonal antibody. It is a highly acidic octapeptide which can be N-terminally fused to the protein of interest. As a very hydrophilic peptide the Flag–tag has a high surface probability. Flag-fusion proteins can be captured by an immunoaffinity column in the presence of Ca2+ and eluted byEDTA at low concentrations, neutral pH and thus, nearly physiological conditions. 相关产品：Bioactive Compound Library Plus | Peptidomimetic Library | Digitonin | 5-Ph-IAA | 3X FLAG peptide | TCEP hydrochloride | Monocrotaline | Tocofersolan | Pronase E (Activity ≥ 7000 U/g) | DPPH | DNase I, Bovine pancreas | NMDI14 | O-Propargyl-Puromycin | Human IgG1 kappa, Isotype Control | Phytohemagglutinin | Hyaluronidase | Biotinyl tyramide | MYLS22 | Pertussis Toxin | N,N-Dimethylformamide | Kifunensine | OVA Peptide (323-339) | L-Tryptophan | 6-Aminonicotinamide | Lauryl maltose neopentyl glycol | Alkyne-phenol | Potassium oxonate | OVA Peptide(257-264) TFA | CHAPS | Teriparatide | 4-Azido-L-phenylalanine 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。
