BODIPY™ FL-C5 染料为明亮的绿色荧光染料,激发和发射波长与荧光素 (FITC) 或 Alexa Fluor™ 488 染料相似。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™ FL-C5 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™ FL-C5 染料(了解更多信息)。

BODIPY™ FL-C5 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™ FL-C5 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 C5 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。

关于 BODIPY™ FL-C5 NHS 酯的详细信息:

荧光基团标记:BODIPY™ FL-C5 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
偶联物的 Ex/Em:504/511 nm
消光系数:87,000 cm-1M-2
分子量:417.22

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
The dynamin-dependent, arrestin-independent internalization of 5-hydroxytryptamine 2A (5-HT2A) serotonin receptors reveals differential sorting of arrestins and 5-HT2A receptors during endocytosis.
Authors:Bhatnagar A, Willins DL, Gray JA, Woods J, Benovic JL, Roth BL
Journal:J Biol Chem
PubMed ID:11069907
'5-Hydroxytryptamine 2A (5-HT2A) receptors, a major site of action of clozapine and other atypical antipsychotic medications, are, paradoxically, internalized in vitro and in vivo by antagonists and agonists. The mechanisms responsible for this paradoxical regulation of 5-HT2A receptors are unknown. In this study, the arrestin and dynamin dependences of agonist- ... More
Real experiences of uHTS: a prototypic 1536-well fluorescence anisotropy-based uHTS screen and application of well-level quality control procedures.

PubMed ID:11689128
This paper describes, for the first time, a true ultra-high throughput screen (uHTS) based upon fluorescence anisotropy and performed entirely in 1536-well assay plates. The assay is based upon binding and displacement of a BODIPY-FL-labeled antibiotic to a specific binding site on 70S ribosomes from Escherichia coli (Kd approximately 15 ... More
Donor-donor energy migration (DDEM) as a tool for studying aggregation in lipid phases.

Journal:Spectrochim Acta A Mol Biomol Spectrosc
PubMed ID:11506035
A BODIPY-labelled sulfatide (N-(BODIPY-FL-pentanoyl)-galactosylcerebroside-sulfate, hereafter abbreviated as BD-Sulfatide) was solubilised at different concentrations in lipid vesicles of 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC). Time-correlated single photon counting experiments show that the fluorescence relaxation is mono-exponential (with a lifetime of 6.5 ns) at molar ratios of BD-Sulfatide: DOPC that are less than 1:100. The fluorescence ... More
Different sphingolipids show differential partitioning into sphingolipid/cholesterol-rich domains in lipid bilayers.
Authors:Wang TY, Silvius JR
Journal:Biophys J
PubMed ID:10969009
Two fluorescence-based approaches have been applied to examine the differential partitioning of fluorescent phospho- and sphingolipid molecules into sphingolipid-enriched domains modeling membrane "lipid rafts." Fluorescence-quenching measurements reveal that N-(diphenylhexatrienyl)propionyl- (DPH3:0-)-labeled gluco- and galactocerebroside partition into sphingolipid-enriched domains in sphingolipid/phosphatidylcholine/cholesterol bilayers with substantially higher affinity than do analogous sphingomyelin, ceramide, or ... More
Functional characterization of coding polymorphisms in the human MDR1 gene using a vaccinia virus expression system.
Authors:Kimchi-Sarfaty C, Gribar JJ, Gottesman MM
Journal:Mol Pharmacol
PubMed ID:12065748
The human MDR1-encoded transporter is a 170-kDa plasma membrane glycoprotein [P-glycoprotein (P-gp)] capable of binding and energy-dependent extrusion of structurally diverse organic compounds and drugs. P-gp seems to play a significant role in uptake, distribution, and excretion of many different drugs. To determine whether common polymorphic forms of P-gp are ... More
