PE-Cy7 is a near-IR dye used primarily in flow cytometry for low-abundance antigens. We offer PE-Cyanine7 dye conjugated to a variety of antibodies, peptides, and proteins, optimized for cellular labeling and detection.

CY7 is a CY dye. CY, short for Cyanine, is a compound consisting of two nitrogen atoms connected by an odd number of methyl units. Cyanine compounds have the characteristics of long wavelength, adjustable absorption and emission, high extinction coefficient, good water solubility and relatively simple synthesis [1] .

Cy7 dye is a C7-cyanine dye having differentially-substituted 2-indolyl units at each end. It has a role as a fluorochrome. It is functionally related to a C7-indocyanine. 1- (5-carboxypentyl)-2- [ (1 E,3 E,5 E,7 Z)-7- (1-ethyl-5-sulfo-3 H -indol-2-ylidene)hepta-1,3,5-trienyl]-3 H …

Available non-sulfonated dyes incude Cy3, Cy3.5, Cy5, Cy5.5, Cy7, and Cy7.5. Cy ® stands for 'cyanine', and the first digit identifies the number of carbon atoms between the indolenine groups. Cy2 which is an oxazole derivative rather than indolenin, is an exception from this rule.

Cy7 from VectorLabs is a near-infrared dye that offers benefits in applications where low background and deep tissue penetration are critical. The near-infrared region is characterized by very low autofluorescence from biological tissues resulting in a much higher signal-to-noise ratio.

Cy7 (Cyanine 7) 是一种近红外花青素荧光染料， 磺化Cy7 (Sulfo-Cy7)是它的水溶型，常常统称为Cy7。 由于它的荧光波长 (em：~770 nm)恰好处于肌体 近红外窗口 I 的区域 (肌体的血液，体液和在此区域背景荧光弱，并且长波长光子的穿透性较强)，所以Cy7常常应用于小动物活体体内成像中。 Cy7荧光肉眼不可见，所以在显微镜头下观察时需要借助CCD相机在成像软件中显示。 另外近红外滤片较少见，很多荧光显微镜 (包括共聚焦显微镜)并不配备，但是流式细胞仪 (flow …

对于近红外染料Cy7和Cy7.5，市场上一般会有两种不同的结构，不同点一般在次甲基桥链上：直链次甲基桥链或者环己烯加固的桥链。 前者是一种比较原始的，直接从ICG染料继承的结构，后者是优化的结构。 和前者相比，后者利用环己烯结构固定次甲基桥链，结构更刚性更稳定，因此荧光量子产率提高了~20%，从而显影更灵敏。 但是需要注意的是这个仅仅只是Lumiprobe公司的说法，已有文献报道专门研究这个问题，发现环己烯固化次甲基桥链不能提高量子产率，两种Cy …

Cyanine 7 (Cy7) dye is a near-infrared fluorescent dye used in research and medical applications. With excitation and emission between 750-800 nm, Cy7 provides deep tissue imaging with minimal autofluorescence. It’s ideal for microscopy, flow cytometry, and in vivo imaging, offering high stability, bright fluorescence, and low toxicity.

PE-Cyanine7 是一种可以为广泛种类激光（包括 488 nm、 532 nm 和 561 nm）所激发的串联荧光团。 如果暴露于光漂白作用、固定过程和更高温度，染料降解常见。 这是一种往往用于流式细胞术中低丰度抗原的明亮染料。 PE-Cyanine7 染料是一种主要用于流式细胞术的近红外荧光团。 我们提供与多种抗体偶联的 PE-Cyanine 7 染料、链霉素亲和素偶联物和细胞凋亡试剂盒。 Brilliant Ultra Violet™ 和 Brilliant Violet™ 是 Becton, Dickinson 公司或其附属公司的商标或注册商标， …
