Synonym: Maleimide PEG DSPE, 1,2-distearoyl-sn-glycero-3-phosphoethanolamine PEG Maleimide, DSPE-PEG-Mal.

Description:

DSPE PEG Maleimide is one of Nanocs reactive phospholipid PEG  reagents that can react with sulfhydryl (thiol, -SH) groups. DSPE (1,2-Distearoyl-sn-Glycero-3-Phosphoethanolamine)  is a saturated 18C phospholipid that is highly hydrophobic. PEG linker (polyethylene glycol), on the other hand, offers good hydrophilicity and water solubility. Maleimide functional DSPE PEG has excellent reactivity towards sulfhydryl/thiol groups derived from various molecules. Reaction between maleimide and thiolproceeds easily at neutral pH. Maleimide PEG DSPE is one of most commonly used reactive phospholipids to conjugate antibodies, peptides or other ligands to the surface of liposome and other lipid PEG nanoparticles. Pegylated phospholipids have longer blood circulation time and higher stability for encapsulated drugs. Nanocs has developed a comprehensive collection of thiol reactive maleimide phospholipid PEG products that have high purity, various molecular weights and excellent chemical reactivity. These lipid PEG conjugates demonstrate excellent amphilphilic properties and offer superior advantages for small and large molecule drug formulation and delivery.

Physical Properties:

  • Form: Solid powder;
  • Color: White;
  • Solubility: Soluble in chloroform and warm water;
  • Reactive group: Maleimide;
  • Reactive to: Sulfhydryl (-SH);
  • Lipid type: 18C PE, saturated;
  • Purity: >95%

Storage Conditions:

产品介绍

花菁染料Sulfo-Cy5-E是一种远红外荧光标记染料，该染料具有高度亲水性和水溶性，含有游离的、未活化的单官能团羧酸。而Sulfo-Cy5-E Maleimide是Sulfo-Cy5-E染料的硫醇反应形式。Maleimide与硫醇基团反应形成硫醚偶联产物。反应可以在pH=7的胺中进行。在中性pH环境中，Maleimide基团不与组氨酸或精氨酸反应。
菁染料是性能优良的荧光染料，摩尔吸光系数在荧光染料中是无可比拟的，其琥珀酰亚胺酯是常用的脂肪氨基标记试剂，广泛用于蛋白、抗体、核酸及其他生物分子的标记和检测。通过改变次甲基链的长度，可改变其荧光发射波长，每增加一个双键，按照Huoffman规则正好红移约100 nm。
水溶性菁染料Cy3和Cy5已成为基因芯片的普遍荧光标记物；另外，Cy5，Cy5.5和Cy7的吸收在近红外区背景非常低，是荧光强度较高、稳定性较好的长波长染料。特别适合于活体小动物体内成像代替放射性元素。

注意事项

1. 产物如需长期储存，我们建议添加BSA和NaN3，并使其终浓度分别为5-10 mg/mL和0.01-0.03%，以防变性和微生物污染。

2. 标记好的抗体溶液应4℃避光保存，如果加入终浓度为50%的甘油，则可储存在-20℃，在这些条件下，产物可稳定保存一年或更长时间。

Qty Add to Cart

Description:

DBCO (Dibenzocyclooctyne) is a cycloalkyne that can reacts with azides via strain-promoted 1,3-dipolar cycloaddition in aqueous solution, a bioorthogonal reaction also termed Cu-free click reaction.  This reaction has excellent selectivity and biocompatibility, such that the complimentary reagents can form covalent bonds with richly functionalized biological systems. The Cu-free click reaction has been a powerful tool in catalyst-free bioconjugation. DBCO reagents posses fast kinetcs and stability in aqueous buffer and they can be used to label azide-modified biomolecules with high specificity and reactivity. 

Physical Properties:

  • Yellow/pale-yellow solid or semi-solid;
  • Soluble in DMSO or DMF;

Storage Conditions:

  • Store at -20 0C, desiccate. Avoid frequent thaw and frozen.

Copper-free Click Reaction Procedures:

Prepare the azide-containing sample in reaction buffer. Add DBCO conjugate to azide containing sample. Recommendation: Add 1 mole equivalent of limiting reagent to 1.5-3.0 mole equivalents of highest abundance reagent. Incubate the reaction at room temperature for 2-4 hours or 2-12 hours at 4 degree celcius. The reaction is now ready for purification.
