近红外活体成像染料 biotium Near-IR CF™ Dyes

产品信息
Near-IR CF™ Dyes
荧光强度Z高、稳定的长波长染料。特别适合于活体动物体内成像


近红外 CF 染料是由 Biotium 公司科研人员开发的一组吸收和发射波长在 650 到 800nm 之间的荧光染 料。近红外 CF 染料是为蛋白标记开发的,荧光强度远比其他相似波长的商业化染料更高, 同时也更稳定。
近红外染料和传统的可见光染料相比有显著的优势。由于细胞和组织的自发荧光在近红外波段Z小,因此在检测复杂生物系统时,近红外染料能提供更高的特异性和灵敏度。同时,由于光波在近红外区段的组织透过性更好,因此近红外染料尤其适合体内荧光成像(活体成像)这一近几年迅速发展的新兴领域。另外,近红外染料也是细胞内/全细胞免疫印记和传统基于膜介质免疫印记的理想染料。

近红外 CF 染料作为新一代的长波长染料,代表了这一领域的重大突破。现有商业化的近红外染料,由于染料的过分聚集以及稳定性差,因而受制于荧光亮度有限的问题。得益于 Biotium 公司科研人员采用的创新型分子工程学技术,近红外 CF 染料克服了上述问题,从而比其他竞争产品具备了关键性的优势:近红外 CF染料荧光强度极高并且非常稳定。例如CF750 亮度高至可以在 633nm 处激发(即在吸收峰值的肩部激发),而此时在 770 nm 左右的荧光发射强度仍然高于基于APC的串联染料。因此,近红外 CF 染料特别适合于流式细胞仪的各种应用,从而可以避免串联染料稳定性等带来的问题。
另外,近红外 CF 染料拥有的结构特性,这使近红外 CF染料和其他竞争产品相比免疫源性更小。因此,在标记同一个蛋白时,可以连接更多的近红外 CF 染料以获得Z大的荧光亮度。同时,这样标记获得的蛋白复合物在体内的半衰期也更长。
后一点,由于近红外 CF 染料优异的溶解性和大于 95% 的活化程度,它的标记效率也远远高于其他近红外染料。

产品特点:



  • 亮度: CF染料在亮度上达到或者超过Alexa Fluor和Cy 等其它商业化的染料.

  • 光稳定性: CF染料的光稳定性在同类染料中.

  • 特异性和体内稳定性:CF标记的抗体具有高度的特异性,同时还能延长抗体在体内成像时的半衰期.

  • 对pH值不敏感: CF染料在很宽的pH值范围内都能维持高亮度的荧光.

  • 溶解性: CF染料在水以及各种有机溶剂中有高度的溶解性.

  • 兼容性:CF染料的光谱特性和其他商业化的染料相似,兼容常见的激发光

    源和现有的各种滤片.

  • 多种颜色可供选择: CF系列染料包括了从紫外到近红外的多种颜色的染料可供选择.




产品应用:



  • 体内成像: CF活化染料和试剂盒非常适合活体成像(小动物体内成像技术)

  • 免疫印记: 用高度交叉吸收后的抗体进行免疫印记可使交叉反应和背景降至Z低

  • 蛋白标记: CF活化染料和试剂盒用于定制标记复合物

  • 流式细胞仪: 优异的非串联标记复合物用于细胞染色

  • 显微成像: 高亮度,光稳定的抗体和活化染料可用于多重标记





图 6. 用胞内CD3抗体或者同型对照孵育Jurkat 细胞并分别用1ug标记了Cy5.5,AlexaFluor680,CF680 或 DyLight680的山羊抗鼠 IgG 荧光二抗染色。用BD FACS Calibur流式细胞仪的FL4通道检测荧光。柱状图代表了CD3阳性荧光值和标记程度(DOL)相似的同型对照相比的信噪比。

图 5.分别用CF750,AlexaFluor750或Cy7标记山羊抗鼠IgG二抗。染料复合物的吸收光谱分别对各自的Z大吸收值做均一化。Cy7和AlexaFluor750染料有较大的肩峰,显示了染料的高度聚集,而这种聚集对整体荧光强度是没有贡献的。

图 8. 用胞内CD3抗体或者同型对照孵育Jurkat 细胞并分别用1ug标记了CF770,Dy­Light 800 或 IRDye800CW的山羊抗鼠 IgG 荧光二抗染色。用BD LSR II 流式细胞仪的633 nm激光器和780/60 nm PMT检测器分析荧光。柱状图代表了相对荧光值的几何均数。

图 7.用鼠抗alpha-tubulin作为一抗,标记了CF680的山羊抗鼠IgG作为二抗染色HeLa细胞。使用以汞电弧灯作为光源的Olympus显微镜拍照,使用Cy5 滤镜组,CCD相机和 ImagePro Express软件获取照片。

图 9. 细胞数量2倍稀释的HeLa细胞培养在一块黑色侧壁,底部透明的96孔板中。将细胞固定、透膜并用鼠抗alpha-tubulin和兔抗COX IV分别作为一抗,选用CF770或IRDye 800(绿色)标记的山羊抗鼠IgG作为二抗,或者选用CF680或IRDye680(红色)标记的山羊抗兔IgG作为二抗染色,抗体的终浓度相同。染色后,细胞被干燥并用Odyssey®红外成像系统(Li-Cor)扫描。上面的两行细胞是用CF染料抗体复合物染色的,对应的下面两行细胞是用商品化购买的IRDye二抗(Li-Cor)染色的。

图 10. 两倍稀释的HeLa 细胞裂解液先在聚丙烯酰胺凝胶上进行电泳,然后转印至硝酸纤维素膜上,并用鼠抗alpha-tubulin和兔抗COX IV分别作为一抗,选用CF770或IRDye 800(绿色)标记的山羊抗鼠IgG作为二抗,或者选用CF680或IRDye680(红色)标记的山羊抗兔IgG作为二抗染色,抗体的终浓度相同。染色后,膜被干燥并用Odyssey®红外成像系统(Li-Cor Biosciences)扫描。对条带定量后发现,CF染料的荧光强度大约是相对应IRDye 二抗(Li-Cor)的3.5倍。
