在免疫组化检测过程中,许多样本组织会产生可通过各种波长滤光片的组织内源性自发荧光,干扰抗体标记的目的蛋白荧光的观察,甚至导致实验失败。为了解决免疫组化实验中的自发荧光,VectorLabs公司专门开发了一款Vector® True VIEW™ Autofluorescence Quenching Kit试剂盒,该产品旨在去除组织切片中由于醛固定、红细胞以及胶原蛋白/弹性蛋白结构造成的自发荧光。该试剂使用方便,无需稀释操作,为即用型试剂。
该试剂盒中含有防自发荧光效果极佳的VECTASHIELD Vibrance Antifade Mounting Media 封片剂(含或不含DAPI两种)。客户无需单独购买封片剂,经济、实用。
注意:该试剂盒对脂褐素造成的组织自发荧光无效。
● 试剂盒组成:
Vector® TrueVIEW™ Reagent A 5 ml
Vector® TrueVIEW™ Reagent B 5 ml
Vector® TrueVIEW™ Reagent C 5 ml
VECTASHIELD Vibrance Antifade Mounting Media 2 ml
VECTASHIELD Vibrance Antifade Mounting Media with DAPI 2ml
其中,货号SP-8400包含a,b,c,d四个组分;货号SP-8500包含a,b,c,e四个组分
● 产品使用方法:
 | 将ReagentA、B、C以1:1:1的比例混合。(注意混合顺序,先将A和B以1:1比例混合10s,再加入C,混匀10s) |  |
 | 将混好后的TrueView试剂滴加到组织样本切片上,将样本完全覆盖,孵育2-5min |  |
 | 使用PBS缓冲液洗片5次,除去多余缓冲液,VECTASHIELD Vibrance Media封片后观察 |  |
● 产品特征:
A 显著降低背景染色并保留特异性抗原染色;
B 提高信噪比;
C 产品稳定,储存在滴瓶中,使用方便;
D 操作简单,快速;整个染色过程仅需2-5min;
E 为使用者提供清晰、明确、真实的染色结果;
F 适用于多种荧光染料的自发荧光去除,包括Alexa 488, Alexa 594, DyLight 488,DyLight 594,FITC,Cyanine 5和GFP;
G SP-8500试剂盒中的封片剂中DAPI浓度较高,可对细胞核进行清晰的染色。
● 产品对自发荧光淬灭效果:

Note:2分钟内即可达到最大淬灭效果。 |  |
● 产品应用举例:
案例一
未经任何处 | 使用Vector® TrueVIEW™处理 |
 |  |
上图为人脾脏组织染色结果:使用VectaFluor TM Duet试剂盒(DK-8818)检测的mouse anti-CD20(red)和rabbit anti-Ki67(green)对人脾组织切片的染色。左图为未经任何处理的染色结果,右图为使用TrueVIEW™Autofluorescence Quenching试剂盒染色结果。于未经处理的染色结果相比,经TrueVIEW™Autofluorescence Quenching试剂盒处理后,自发荧光显著减少。 |
案例二
 | A-D图为人肾脏切片(石蜡切片) 染色结果,实验中使用anti-AE1 /AE3抗体对角蛋白进行染色(绿色)。A图未经处理,B-D图经TrueVIEW™Quencher Kit处理。自发荧光明显减弱。延长曝光时间,阳性信号强度也随之增强。 |
 |
案例三
未经任何处理 | 使用TrueVIEW Treatment Mounted with Vibrance + 3x DAPI处理 |
 |  |
上图为人胰腺组织染色结果:绿色为insulin的染色。左图为未经任何处理的染色结果,右图为使用TrueVIEW Treatment Mounted with Vibrance + 3x DAPI(SP-8500)试剂盒染色结果。与未经处理的染色结果相比,经该试剂盒处理后,自发荧光显著减少,核染色显著增强。 |
案例四
未经任何处理 | 使用TrueVIEW Treatment Mounted with Vibrance + 4x DAPI处理 |
 |  |
上图为人前列腺组织染色结果:红色为上皮细胞的染色。左图为未经任何处理的染色结果,右图为使用TrueVIEW Treatment Mounted with Vibrance + 4x DAPI(SP-8500)试剂盒染色结果。与未经处理的染色结果相比,经该试剂盒处理后,自发荧光显著减少,核染色显著增强。 |
