TCRβ-CD4/CD19-中分出Synd-1+IgM+浆细胞(E),TCRβ-CD19+中分出Synd-1+IgM+浆母细胞(F)和Synd-1-群体,后者进一步通过PD-L2-MHCII+IgM+IgD+分出活化 B 细胞(G)、PD-L2+IgM+记忆 B 细胞(H) 根据CD44/CD62L分出初始、效应记忆和中央记忆...
解析 小鼠B细胞 CD45R/B220(相应mAb为RA3- 6B2)是小鼠全B细胞最常用标记,但这个标记也表达于活化T细胞、活化NK细胞和NK祖细胞.相对来说,CD19是B细胞较特异的标记.结果一 题目 想请问用CD45R(B220)的流式抗体是否可以特异性地分离出小鼠B淋巴细胞?还是用CD19好呢? 答案 小鼠B细胞 CD45R/B220(相应mAb为RA3-...
NK cells in the CD19- B220+ bone marrow fraction are increased in senescence and reduce E2A and surrogate light chain proteins in B cell precursors. NK cells in the CD19- B220+ bone marrow fraction are increased in senescence and reduce E2A and surrogate light chain proteins in B cell ...
tyrosine kinases c-Kit and Flt3/Flk-2 and of the human CD25 gene expressed as a transgene under the regulation of the mouse lambda5 promoter in the bone marrow of 1-week-old mice allows us to identify three stages of B lymphocyte development before the CD19(+)c-Kit(+) pre-B-I ...
但这个标记也表达于活化T细胞、活化N械游基放七K细胞和NK祖细胞.相对来说,CD19是B细胞较特异的标记.
估计楼主都做完了吧，，，选择CD19的比较多，不过B220在B细胞上出现的时间跟CD19差不多 ...

In addition, the almost complete absence of peripheral B220+ B-lineage cells in μMT mice allowed the anatomical localization of the B220+CD19–CD11c+ cells to the red pulp and the T cell areas in the spleen. Taken together, our findings indicate that the mouse bone marrow contains a ...
Interestingly, we identify a new immune cell type: CD19(+)B220(-) BST-2(+), which we name G8-ICs. These cells appear during peripheral infection and enter the CNS. G8-ICs express high levels of MHC class II, stain for viral Ag, and are localized in the paracortical zone of ...
