| 产品介绍 | background: 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.

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 |

文献和实验当FITC在碱性溶液中与抗体蛋白反应时,主要是蛋白质上赖氨酸的r氨基与荧光素的硫碳胺键(thiocarbmide)结合,形成FITC-蛋白质结合物,即荧光抗体或荧光结合物。一个IgG分子中有86个赖氨酸残基,一般最多能结合15~20个,一个IgG分子可结合2~8个分子的FITC,其反应式如下FITC-N=C=S + N-H2-蛋白质 → FITC-NS-C-N-H2-蛋白质常用Marsshall(1958)法标记荧光抗体,也可以根据条件采用Chadwick等标记法或Clark
ml三蒸水中即成; 方法与步骤: 根据Marshall氏法高效价的抗人球蛋白兔免疫血清,分离球蛋白。 1. 用0.15 mol/L NaCl的盐水及0.15 mol/L pH9.0的NaHCO3-Na2CO3缓冲液稀释使每毫升内含抗体10mg,缓冲液为总量的10%; 2. 将以上溶液降温至4℃,按蛋白:荧光素=50—80mg:1mg的比例加入异硫氰酸荧光素,在0—4℃下电磁搅拌12—14h; 3.用半饱和硫酸铵将标记球蛋白
5. 过柱。取透析过夜的标记物,过葡萄糖凝胶G-25或G-50柱,分离出游离荧光素,收集标记的荧光抗体进行鉴定。
