Description:

DBCO (dibenzocycolctyne) PEG Biotin derivatives can go Click Chemistry reaction without a need of any metal catalysts. The strain-promoted 1,3-dipolar cycloaddition of cyclooctynes and azides, also termed as the Cu-free click reaction, is a bioorthogonal reaction that enables the conjugation of two molecules in aqueous solution. DBCO PEG derivatives possess fast kinetics and stability in aqueous buffer. DBCO reagents can be used to label azide-modified biomolecules spontaneous without the need for toxic Cu catalysts. PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces.

Physical Properties:

  • White solid or viscous liquid depends on molecule weight;
  • Soluble in regular aqeous solution as well as most organic solvents;

Copper-free Click reaction procedures:

  • Prepare the azide-containing reagents in reaction buffer.
  • Add DBCO reagents to azide containing reagents. Add 1 mol equivalent of limiting reagent to 1.5~3.0 mol equivalents of abundance reagent.
  • Incubate the reaction at room temperature for 2~4 hours or 2~12 hours at 4 0C.
  • Purify conjugates either by dialysis or size-exclusion chromatograph.

Storage Conditions:

  • Store at -20 0C, dessicate. Protect from light. Avoid frequent thaw and freeze.

3.负压吸气端和正压打气端都配置了滤芯和缓冲杯套件组,负压吸气端套件组可以防止液体、粉尘等倒吸进泵损坏设备;正压打气端的套件组可以过滤掉空气中的杂质颗粒物和水汽,从而输送出干燥、清洁的气体。
4.无论是负压还是正压端均标配设计了调节阀,可以根据实际的使用需要调节真空度和压力。
5.采用双表设计,真空表和压力表各自独立,可以分别显示真空度和正压值,观察时更加简明。
6.整机插电即可使用,不需要加入泵油或连接水源,无油干式运行,使用方便免去日后维保的麻烦,同时工作时噪音值也更低。

Description:

Dibenzocycolctyne (DBCO) PEG NHS derivatives can go Click Chemistry reaction without a need of any metal catalysts. The strain-promoted 1,3-dipolar cycloaddition of cyclooctynes and azides, also termed as the Cu-free click reaction, is a bioorthogonal reaction that enables the conjugation of two molecules in aqueous solution. DBCO PEG derivatives possess fast kinetics and stability in aqueous buffer. DBCO reagents can be used to label azide-modified biomolecules spontaneous without the need for toxic Cu catalysts. PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces.

Physical Properties:

  • White solid or viscous liquid depends on molecule weight;
  • Soluble in regular aqeous solution as well as most organic solvents;

Copper-free Click reaction procedures:

  • Prepare the azide-containing reagents in reaction buffer.
  • Add DBCO reagents to azide containing reagents. Add 1 mol equivalent of limiting reagent to 1.5~3.0 mol equivalents of abundance reagent.
  • Incubate the reaction at room temperature for 2~4 hours or 2~12 hours at 4 0C.
  • Purify conjugates either by dialysis or size-exclusion chromatograph.

Storage Conditions:

  • Store at -20 0C, dessicate. Protect from light. Avoid frequent thaw and freeze.
