About InVivoMAb anti-mouse CD276 (B7-H3)
The MJ18 monoclonal antibody reacts with mouse CD276 also known as B7-H3. CD276 is a type I transmembrane protein and a member of the B7 family of co-stimulatory proteins. CD276 is expressed weakly on activated lymphocytes, macrophages, dendritic cells, nasal and airway epithelial cells, osteoblasts, and some tumor cell lines. A soluble form of CD276 is also secreted by monocytes, dendritic cells, and activated T cells. The biological role of CD276 is still under investigation however, recent studies suggest a negative regulatory role for CD276 in T cell responses. The MJ18 antibody has been shown to block CD276 when administered in vivo.

其同型为;percp-cy5.5(25ug包装)浓度:0.2mg/ml,
那么如果CD45RA抗体如果加入20ul,那同型抗体应该加入多少ml:
我自己的初步计算是:1ul的3分之1.不知道我算对了吗?应该怎么加才好呢?
比如你用anti-MHC-II,mouse IgG1-FITC,那同型就用非特异性的mouse IgG1-FITC,同样浓度

不存在荧光重叠的两个抗体不需要调节补偿。
样本为PBMC,想用三色标记Treg细胞,分别为CD4-PECY,CD25-Fitc,Foxp3-PE,想知道如何设置荧光补偿,用的是BD的流式仪,1、是设置阴性管一个,单阳性管每种一个,样品管一个么?
荧光素强度依次为PE, PECY5 APC FITC, PE最强,FITC最弱。 所以,建议抗体组合为:
Foxp3-PE,CD4-FITC,CD25-PECy5.5或者CD25-APC。
同时购买三个相应的同型对照抗体。
样品管设置如下:
1. cell + FITC-isotype + Pecy5.5( or APC)-isotype + PE-isotype
2. Cell + FITC-isotype + CD25-mAb + PE-isotype
3. Cell + PE-mAb + FITC-isotype + Pecy5.5( or APC)-isotype
4. Cell + CD4-FITC + Foxp3-PE + CD25 -PECy5.5( or APC)。 [这一管的数据可以拿来分析用]。
在充分了解调整电压和补偿原理的基础上,也可以做一些简化。如果不太懂,就按照这个来。其中Foxp3的抗体和同型对照抗体都是在固定破膜以后再加,不是与CD4或者CD25同时加。
