Medchemexpress LLC Diazo biotin-PEG3-alkyne | 1884349-58-9 | MFCD28505544 | 98.1% | C39H53N7O9S | 10MG
Diazo Biotin-PEG3-alkyne is a multifunctional chemical linker combining a photo-reactive diazo group, a biotin affinity tag, a PEG3 spacer, and a terminal alkyne. It is designed for conjugation to azide-containing biomolecules via copper-catalyzed azide-alkyne cycloaddition (CuAAC) and for downstream affinity capture or detection with biotin-streptavidin systems. Supplied as a high-purity powder for research use.
- Contains terminal alkyne for CuAAC (click chemistry).
- Provides biotin tag for affinity capture with streptavidin.
- Includes PEG3 spacer to improve solubility and flexibility.
- Features a photo-reactive diazo group for photoaffinity labeling.
- High purity suitable for biochemical and proteomic workflows.
Medchemexpress LLC Cy3 NHS ester | 1393363-07-9 | 99.5% | 590.15 | 50 MG
Cy3 NHS ester 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 characteristics of long wavelength, adjustable absorption and emission, high extinction coefficient, good water solubility, and relatively simple synthesis. CY dyes are often used for the labeling of proteins, antibodies, and small molecular compounds. For the labeling of protein antibodies, the combination can be completed through a simple mixing reaction.
- Long wavelength
- Adjustable absorption and emission
- High extinction coefficient
- Good water solubility
- Relatively simple synthesis
- Used for labeling of proteins, antibodies, and small molecular compounds
