Description | Annexin I, also knows as lipocortin I (Lipo1), belongs to the family of annexins. These proteins are thought to control the biosynthesis of the potent mediators of inflammation, prostaglandins and leukotrienes. In two lipocortins (I and II) a short amino-terminal sequence distinct from the core structure has potential regulatory functions which are dependent on its phosphorylation state. The gene in the mouse encodes a protein of 346 amino acid residues. Mouse Lipo1 gene spans about 17 kb and is divided into 13 exons. Annexin I gene, mapped to 9q11-q22, is located on mouse chromosome 19. Annexin I acts through the formyl peptide receptor on human neutrophils. Peptides derived from the unique N-terminal domain of annexin I serve as FPR ligands and trigger different signaling pathways in a dose-dependent manner. |

同形像统计图
阴性对照(Isotype Control):非特异荧光的强弱取决于抗体浓度、单克隆荧光抗体特异性和纯度,应与试验管抗体相对应。在多色分析时,同型对照应与其它抗体同时使用,以避免补偿造成的误差
血小板体外活化试验:使用正常人活化标本作为阳性质控;使用正常人未活化标本作为阴性质控
血小板自身抗体检测:使用含有已知血小板抗体的血清与血小板孵育,作为阳性质控;使用不含血小板抗体的血清与血小板孵育,作为阴性质控
血小板表面抗原缺失:如巨血小板症血小板表面CD42a/CD42b缺失,血小板无力症血小板表面gpIIb/IIIa,即CD41/CD61缺失或异常。使用正常人标本做阳性对照,抗体的同型对照做阴性对照
