    Antibody Type : Mouse Monoclonal Antibody ( Mouse mAb Service Platform )
    克隆号 : 03

    抗体宿主 : Mouse IgG2b
    缓冲液 : 0.2 μm filtered solution in PBS, 5% trehalose may be added in some batches. Please read the hardcopy of COA or contact our customer service to confirm the formulation.
    制备方法 : This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, human cell-derived, recombinant human SIRPA ( rh SIRPA ; Catalog#11612-H08H ; NP_542970.1 ; Met 1 - Arg 370 ). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography
    SIRPA / CD172A抗体背景综述
    Tyrosine-protein phosphatase non-receptor type substrate 1, also known as SHP substrate 1, Inhibitory receptor SHPS-1, Brain Ig-like molecule with tyrosine-based activation motifs, Macrophage fusion receptor, CD172 antigen-like family member A, SIRPA and CD172a, is a single-pass type I membrane protein which contains two Ig-like C1-type (immunoglobulin-like) domains and one Ig-like V-type (immunoglobulin-like) domain. SIRPA is ubiquitously expressed. It is highly expressed in brain and detected at lower levels in heart, placenta, lung, testis, ovary, colon, liver, small intestine, prostate, spleen, kidney, skeletal muscle and pancreas. It is also detected on myeloid cells, but not T-cells. SIRPA is an immunoglobulin-like cell surface receptor for CD47. SIRPA acts as docking protein and induces translocation of PTPN6, PTPN11 and other binding partners from the cytosol to the plasma membrane. SIRPA supports adhesion of cerebellar neurons, neurite outgrowth and glial cell attachment. It may play a key role in intracellular signaling during synaptogenesis and in synaptic function. SIRPA is involved in the negative regulation of receptor tyrosine kinase-coupled cellular responses induced by cell adhesion, growth factors or insulin. It mediates negative regulation of phagocytosis, mast cell activation and dendritic cell activation.

    • 抗体的发展历程

      脾细胞与小鼠骨髓瘤细胞(P3-X63/Ag8)融合,融合的细胞既获得了亲代脾细胞分泌特异性抗体的特性,又具有骨髓瘤细胞大量繁殖的能力,成为一种既能分泌特异性抗体又能长命的杂交瘤细胞。该技术为抗体的分子生物学研究提供了全新的手段。极大地促进了免疫学,遗传学,分子生物学的快速发展。   但传统抗体目前也面临诸多问题,如: 每使用一管新抗体都需要进行滴定测试; 多种同型对照,实验设计繁琐; 需要添加Fc阻断试剂; 抗体不佳,阳性细胞群不明显; 抗体作为细胞生物学和生物化学中最重要的试剂之一,科学界每年在这类
