| 产品介绍 | CD20 is a non glycosylated protein with a molecular weight of 35 or 37 kDa depending on the degree of phosphorylation. Although not a member of the tetraspanin superfamily of cell surface receptors, it crosses the cell membrane four times. The CD20 antigen is present on human pre B lymphocytes and on B lymphocytes at all stages of maturation, except on plasma cells. Low level expression of the CD20 antigen has been detected on normal T lymphocytes. The CD20 molecule is involved in regulation of B cell differentiation, presumably via its reported function as a Ca++ channel subunit. Function: This protein may be involved in the regulation of B-cell activation and proliferation Subcellular Location: Membrane; Multi-pass membrane protein. Tissue Specificity: Expressed on B-cells. Post-translational modifications: Phosphorylated. Might be functionally regulated by protein kinase(s). DISEASE: Defects in MS4A1 are the cause of immunodeficiency common variable type 5 (CVID5) [MIM:613495]; also called antibody deficiency due to CD20 defect. CVID5 is a primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B-cells is usually in the normal range, but can be low. Similarity: Belongs to the MS4A family.

B淋巴细胞标志物 CD20是B细胞特异性抗原,其表达呈细胞类型一种质膜蛋白质,参与信号传导作用,此抗体识别大多数B细胞上的一种抗原。多用于标记B淋巴细胞及B细胞淋巴瘤。 CD20一般不与T细胞交叉反应,对B细胞淋巴瘤和急慢性淋巴细胞白血病等有较好的细胞特异性,因此在恶性淋巴瘤,尤其是T或B细胞淋巴瘤的分类上,CD20是最常用的B细胞标志。 |

抗体的结构决定了其对应的功能,同一抗体的V区和C区的氨基酸组成和顺序不同,决定了其功能上的差异。V区和C区的组成和结构,决定了抗体的生物学功能。 图1:抗体的主要功能(图片来源:Abbas et al: Cellular and Molecular Immunology, 7e.) 1、特异性识别功能 抗体可以通过其结构上的可变区域与抗原结合,同时,具有极高的特异性。这种特异性识别功能可以使抗体识别和结合到感染的病原体,肿瘤细胞等不同种类的分子,帮助免疫系统识别并定位到这些分子,进而启动
在生命科学和医学基础研究中,或多或少都需要用到抗体。抗体的应用场景不同、标记物众多,且针对同一标记物市场上往往有多个抗体可供选择,那么,我们如何从成百万上千万种抗体中,挑选出我们想要的那支呢? 在我们6月份的关于抗体的调研活动中,我们发现,大家更多的是去参考文献或专利中的材料和方法部分,这无疑很大程度上保证了抗体的有效性。其次有45%和34%的受访者会用到百度和谷歌,然而这两个搜索引擎覆盖面颇广,经常会出现抗体无关的搜索结果,而专业用于查找抗体的网站,大家却知之甚少。 因此,本次文章中
