| 产品介绍 | background: CD45 is a family of single chain transmembraneous glycoproteins consisting of at least four isoforms (220, 205, 190, 180 kDa) which share a common large intracellular domain. Their extracellular domains are heavily glycosylated. The different isoforms are produced by alternative messenger RNA splicing of three exons of a single gene on chromosome 1. CD45 is expressed on cells of the human hematopoietic lineage (including hematopoietic stem cells) with the exception of mature red cells. It is not detected on differentiated cells of other tissues. It is likely that CD45 plays an important role in signal transduction, inhibition or upregulation of various immunological functions. Antibodies recognising a common epitope on all of the isoforms are termed CD45 whilst those recognising only individual isoforms are termed CD45RA or CD45RO etc. Function: Protein tyrosine-protein phosphatase required for T-cell activation through the antigen receptor. Acts as a positive regulator of T-cell coactivation upon binding to DPP4. The first PTPase domain has enzymatic activity, while the second one seems to affect the substrate specificity of the first one. Upon T-cell activation, recruits and dephosphorylates SKAP1 and FYN. Dephosphorylates LYN, and thereby modulates LYN activity. Subunit: Binds GANAB and PRKCSH. Interacts with SKAP1. Interacts with DPP4; the interaction is enhanced in a interleukin-12-dependent manner in activated lymphocytes. Subcellular Location: Membrane; Single-pass type I membrane protein. Membrane raft. Note=Colocalized with DPP4 in membrane rafts. Post-translational modifications: Heavily N- and O-glycosylated. DISEASE: Defects in PTPRC are a cause of severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-positive (T(-)B(+)NK(+) SCID) [MIM:608971]. A form of severe combined immunodeficiency (SCID), a genetically and clinically heterogeneous group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels. Patients present in infancy recurrent, persistent infections by opportunistic organisms. The common characteristic of all types of SCID is absence of T-cell-mediated cellular immunity due to a defect in T-cell development. Genetic variations in PTPRC are involved in multiple sclerosis susceptibility (MS) [MIM:126200]. MS is a neurodegenerative disorder characterized by the gradual accumulation of focal plaques of demyelination particularly in the periventricular areas of the brain. Peripheral nerves are not affected. Onset usually in third or fourth decade with intermittent progression over an extended period. The cause is still uncertain. Similarity: Belongs to the protein-tyrosine phosphatase family. Receptor class 1/6 subfamily. Contains 2 fibronectin type-III domains. Contains 2 tyrosine-protein phosphatase domains.

CD45在活化信号转导中起到调节作用 在确定CD45为一种PTPase之前就已证实了CD45参于细胞的活化和生长调节。 抗CD45抗体可以抑制PHA或CD3交联所介导的T细胞增殖，还可抑制NK或细胞毒性T细胞对靶细胞的杀伤，抑制经CD2、CD3以及CD8膜分子介导的信号转导作用。 白细胞共同抗原是五种或更多的高分子量糖蛋白组成的蛋白家族，主要位于白细胞表面，包括T、B淋巴细胞、多形核白细胞、单核细胞等，而在红细胞、血小板及非造血系统中不表达。因此是区分淋巴瘤/白血病和非造血组织肿瘤（如未分化小细胞癌、小圆细胞肉瘤）的特异性标记物。该抗体主要用于淋巴瘤和未分化小细胞癌的鉴别诊断。 |

文献和实验相关实验
免疫荧光技术（Immunofluorescence technique ）又称荧光抗体技术，是标记免疫技术中发展最早的一种。它是在免疫学、生物化学和显微镜技术的基础上建立起来的一项技术。很早以来就有一些学者试图将抗体分子与一些示踪物质结合，利用抗原抗体反应进行组织或细胞内抗原物质的定位。Coons等于1941年首次采用荧光素进行标记而获得成功。这种以荧光物质标记抗体而进行抗原定位的技术称为荧光抗体技术（fluorescentantibodytechnique）。用荧光抗体示踪或检查相应抗原
内腔可产生高强度的磁场，足以分离磁微粒标记的细胞，无需分离柱提供提供更高强度的磁场。由于磁微粒极小，不会影响靶细胞的流式分析结果，因此不需要去除。除了现有的定型产品外，客户可选择EasySep® PE、FITC或生物素分选系统与自己的PE、FITC或生物素—偶联的单抗相结合，来富集任何所需的细胞。如果您有自己的小鼠IgG1抗任何细胞的抗体, 也可以使用“Do-It-Yourself”试剂盒做成TAC，用来分选您想要的细胞。此外，还可以根据您的特殊需要，专门为您设计定做试剂盒。用于正选小鼠的细胞标记
#01 什么是同型对照？ 同型对照（Isotype Control），是指与使用的流式抗体具有相同种属来源、亚型、荧光标记物、使用剂量和浓度，但对目标靶点无特异性结合的抗体。同型对照通常用来消除抗体与抗原的非特异性结合造成的背景染色。 #02 为什么要做同型对照？ 流式抗体与靶标的结合，是通过抗体的 Fab 端与靶标 Marker 进行特异性结合而完成的。白细胞（除T细胞外）表面大多表达 CD16、CD32、CD64 等 Fc 受体，这些受体可与各种抗体的 Fc 端非特异性结合，出现非特异
