The antibody has a proven strong biotin-streptavidin/HRP staining at a 1/1000 - 1/2000 dilution in rat globus pallidus and spinal cord. Staining is completely eliminated by pretreatment with 50 µg of Leucine Enkephalin per mL of diluted antiserum. Pretreatment with 50 µg of Methionine Enkephalin per mL of diluted antiserum also significantly blocks staining.
Photo Description: Low magnification IHC image of leucine enkephalin staining in the rat globus pallidus. The tissue was fixed with 4% formaldehyde in phosphate buffer, before being removed and prepared for vibratome sectioning. Floating sections were incubated at RT in 10% goat serum in PBS, before standard IHC procedure. Primary antibody was incubated at 1:2000 for 48 hours, goat anti-rabbit secondary was subsequently added for 1 hour after washing with PBS. Light microscopy staining was achieved with standard biotin-streptavidin/HRP procedure and DAB chromogen.

同形像统计图
选用和特异性抗体同种亚型的,同样荧光素标记的抗体,采用同样的染色步骤染同样浓度的细胞。然后上机检测。如果细胞有非特异性的结合,那同型对照的荧光强度可能会比未染色的阴性对照要高一些。
同型对照只用于那种阳性和阴性之间没有明确分解的情况。如果阳性细胞群非常清楚,是不需要同型对照的。另外,在多色同染的情况下,也不采用同型对照,而是采用FMO(fluorensence minus one)对照。
另外,对于同型对照的使用,也有很多反对意见。就算是同型抗体,也可能会有不同的亲和力,并不一定就能真实反应非特异性的结合。
同型对照(阴性对照)管:A同型+B同型+C同型
单阳性对照
A检测管:A+B同型+C同型
B检测管:B+A同型+C同型
C检测管:C+A同型+B同型
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。

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?
