产品描述: | OVA(257-264) is a polypeptide composed of 8 amino acids, which is a class I (Kb) - restricted epitope peptide of OVA, while OVA is an octamer peptide from ovalbumin presented by class I MHC molecule H-2Kb OVA Peptide(257-264) TFA 是 OVA 的 I 类 (Kb)-限制性肽表位,它是一种八聚体肽,可以来自 I 类 MHC 分子 H-2Kb 所呈现的卵清蛋白。 | ||||
体外实验: | TAP1-I- and C57BL/6 macrophages may process Crl-OVA and full-length OVA in different cellular compartments and that the protein context of the OVA Peptide (257-264) epitope influences the extent of TAP-independent processing for MHC class I presentation. OVA Peptide (257-264) epitope is presented with a differential dependence on the TAP transporter depending on the protein context of the OVA epitope: OVA Peptide (257-264) contained within the MBPCrl-OVA or Crl-OVA bacterial fusion proteins is presented with little dependence on the TAP transporter, while OVA Peptide (257-264) contained within full-length ovalbumin is largely dependent on the TAP transporter, regardless of whether recombinant OVA is expressed in bacteria or the native protein is coupled to polystyrene beads. OVA肽(257-264)TFA是OVA的I类(Kb)限制性肽表位,OVA是由I类MHC分子H-2Kb呈现的来自卵清蛋白的八聚体肽。TAP1-I-和C57BL/6巨噬细胞可在不同的细胞室中处理Crl OVA和全长OVA,并且OVA肽(257-264)表位的蛋白质背景影响MHC I类呈递的TAP独立处理的程度。OVA肽(257-264)表位对TAP转运体的依赖性取决于OVA表位的蛋白质背景:MBPCrl OVA或Crl OVA细菌融合蛋白中包含的OVA肽(257-264)对TAP转运体的依赖性很小,而OVA肽(257-264)包含在全长卵清蛋白中的蛋白在很大程度上依赖于TAP转运体,无论重组卵清蛋白是在细菌中表达还是天然蛋白与聚苯乙烯珠偶联。 |

OVA(257-264) 使用说明:
储存液制备: 将试剂置于室温下至少20min回温,低速离心,将1mg OVA Peptide 257-264粉末加入1ml去离子水,低速涡旋混合或用枪上下吹匀,即得到1mg/ml的储存液。
备注:请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;一旦配成溶液,请分装保存,避免反复冻融造成的产品失效。
储备液的保存方式和期限:-80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture)。-80°C储存时,请在6个月内使用,-20°C储存时,请在1个月内使用。
工作液配制: 根据具体实验要求或参考文献选择合适的工作浓度,用合适的缓冲液或介质稀释即可。例如,体内诱导CD8+T细胞应答的常用工作浓度为1ug/ml。
