BODIPY™ 576/589 染料为明亮的红色荧光染料,激发和发射波长与罗丹明红™ 和 Alexa Fluor™ 568 相似。它具有高消光系数和荧光量子产率,对溶剂极性和 pH 值变化相对不敏感。与高水溶性荧光基团 Alexa Fluor™ 488 染料和荧光素 (FITC) 不同,BODIPY™ 染料具有独特的疏水特性,适用于染色脂质、膜和其他亲脂性化合物。BODIPY™ 576/589 染料具有相对较长的激发状态寿命(通常为 5 纳秒或更长),可用于基于荧光偏振的测定以及多光子激发的大型双光子横截面。除反应性染料配方外,我们还提供可与多种抗体、肽、蛋白、示踪剂和扩增底物偶联并且针对细胞标记和检测进行优化的 BODIPY™ 576/589 染料。

BODIPY™ 576/589 的 NHS 酯(或琥珀酰亚胺酯)是将该染料与蛋白或抗体偶联的较常用工具。NHS 酯可用于标记蛋白的伯胺 (R-NH2)、胺修饰的寡核苷酸和其他含胺分子。由此产生的 BODIPY™ 576/589 偶联物显示明亮荧光、窄发射带宽和相对较长的激发状态寿命,可用于荧光偏振测定和双光子激发 (TPE) 显微镜检查。

该反应性染料在荧光基团与 NHS 酯基团之间存在一个 C3 烷基间隔。该间隔有助于将荧光基团与连接点分离,可能减少荧光基团和其偶联的生物分子的相互作用。

荧光基团标记:BODIPY™ 576/589 染料
反应性基团:NHS 酯(琥珀酰亚胺酯)
反应性:蛋白和配体、胺修饰的寡核苷酸上的伯胺

典型偶联反应
胺反应性试剂可与几乎任何蛋白或肽偶联;提供的方案针对 IgG 抗体进行了优化。可以与任何量的蛋白发生反应,但为了获得较佳结果,蛋白浓度应至少为 2 mg/mL。我们建议使用三种不同摩尔比的反应性试剂对蛋白进行三种不同程度的标记。

BODIPY™ NHS 酯通常溶于高质量的无水二甲基甲酰胺 (DMF) 或二甲亚砜 (DMSO) 中,并在 0.1-0.2 M 碳酸氢钠缓冲液(pH 值 8.3)中于室温下进行反应,持续 1 小时。由于末端胺的 pKa 低于赖氨酸 ε -氨基基团的 pKa,您可以使用接近中性 pH 值的缓冲液对胺末端进行更具选择性的标记。

偶联物纯化
通常使用凝胶过滤柱(如 Sephadex™ G-25、BioGel™ P-30 或等同产品)将标记抗体与游离 BODIPY™ 染料分离。对于更大或更小的蛋白,选择具有适当截留分子量的凝胶过滤介质或通过透析纯化。我们提供了多种优化的纯化试剂盒,可用于不同量抗体偶联物:
0.5-1 mg 用抗体偶联物纯化试剂盒 (A33086)
20-50 µg 用抗体偶联物纯化试剂盒 (A33087)
50-100 µg 用抗体偶联物纯化试剂盒 (A33088)

Abstract
Wavelength-resolved fluorescence detection in capillary electrophoresis.
Authors:Timperman AT, Khatib K, Sweedler JV
Journal:Anal Chem
PubMed ID:7864386
'A multichannel laser-induced fluorescence detector for capillary electrophoresis is described. The detection system combines yoctomole limits of detection with the simultaneous acquisition of entire fluorescence emission spectra. An Ar/Kr mixed-gas ion laser provides great flexibility in excitation wavelengths, and a holographic grating and charge-coupled device detector combination allows a 500-nm ... More

'We designed and synthesized new, fluorescent, non-natural amino acids that emit fluorescence of wavelengths longer than 500 nm and are accepted by an Escherichia coli cell-free translation system. We synthesized p-aminophenylalanine derivatives linked with BODIPY fluorophores at the p-amino group and introduced them into streptavidin using the four-base codon CGGG ... More
Detection of the DeltaF508 mutation in the CFTR gene by means of time-resolved fluorescence methods.

Journal:Bioelectrochem Bioenerg
PubMed ID:10379562
A rapid recognition in the base sequence of nucleic acids is an important prerequisite toward the diagnosis of genetic diseases and their carrier states. We have developed a hybridisation method in which a fluorescently labeled oligonucleotide is used to detect point mutations in a target by a simple fluorescence lifetime ... More
Molecular dynamics of labeled oligonucleotide probes used for the detection of point mutations in DNA.

PubMed ID:10408923
The fluorescent label BODIPY 576-589 linked to the 5-end of an oligonucleotide via alkyl chain linkers can be used as a probe to detect point mutations in DNA. We have employed fluorescence anisotropy decay and dynamic fluorescence resonance energy transfer (FRET) in order to investigate the molecular origin of the ... More
Systematic evaluation of transcellular activities of secretory phospholipases A2. High activity of group V phospholipases A2 to induce eicosanoid biosynthesis in neighboring inflammatory cells.
Authors:Wijewickrama GT, Kim JH, Kim YJ, Abraham A, Oh Y, Ananthanarayanan B, Kwatia M, Ackerman SJ, Cho W
Journal:J Biol Chem
PubMed ID:16476735
The mechanisms by which secretory phospholipase A2 (PLA2) exerts cellular effects are not fully understood. To elucidate these mechanisms, we systematically and quantitatively assessed the activities of human group IIA, V, and X PLA2s on originating and neighboring cells using orthogonal fluorogenic substrates in various mixed cell systems.
