p2Ca 产品活性：p2Ca是8聚体肽，是天然加工并呈递给Ld同种异体T细胞克隆2C的配体。 产品来源： https://www.medchemexpress.cn/p2Ca.html 研究领域：Others 作用靶点：Others 结构分类：其他类 In Vitro: p2Ca and QL9 peptides assume distinct conformations when bind to Ld and, furthermore, demonstrate that there is flexibility in peptide binding within the MHC class I cleft. Ld antigenic peptide p2Ca (LSPFPFDL) is 8-mer that lack the proline at position 2 and thus use alternative amino-terminal anchors. The p2Ca octamer is identified as the ligand that is naturally processed and presented to the Ld-alloreactive T cell clone, 2C. p2Ca, is immunodominant in allorecognition of the murine MHC class I molecule H-2Ld. The majority of Ld-alloreactive T-cell clones are specific for Ld-p2Ca and this immunodominance is not due to peptide cross-reactivity. p2Ca is a ubiquitously expressed self-peptide. p2Ca is derived from the mouse mitochondrial enzyme α-ketoglutarate dehydrogenase. p2Ca is present in every tissue of BALB/c mice that has been examined, including the spleen and thymus. It is also expressed by mouse tumor cell lines such as the mastocytoma P815. CTL derived in vitro recognize specifically the p2Ca/L d complex and use Vβ8 regions predominantly. The cultured cells lyse target cells with lower levels of p2Ca than the levels used for induction. This result suggests that it may be possible to use peptides at high concentrations to elicit CTL that react with endogenous levels of a peptide/class I complex. In Vivo: BALB/c mice, coinjected with a syngeneic BALB/c myeloma and exogenous p2Ca, are able to reject the tumor. The p2Ca/L d system may thus provide a model for evaluating the parameters for effective immunotherapy with tumor-associated peptides. 相关产品：Digitonin | 5-Ph-IAA | FLAG peptide | 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 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。
