Grainger BRIGHT DYES Dye Tracer Liquid, Blue
The Bright Dyes Dye Tracer Liquid Blue is a blue liquid dye used to detect leaks in plumbing and HVAC systems. It contains a concentrated blue dye that mixes with water. When added to a system, any leaks will release blue-dyed water for easy leak detection. This product is rated for use in all potable water systems and is safe for PVC, CPVC, copper and other common plumbing materials. It comes in a 16 oz plastic bottle with an easy pour spout that allows controlled dispensing into systems. This professional-grade leak detector provides an effective method to pinpoint leaks.
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

Dojindo Molecular Technologies Inc Biotin-PEAC5-maleimide (10MG), reacts with thiol compounds, such as proteins or peptides with sulfhydryl groups at pH 7-7.5 to create a thioether bond.
Avidin-biotin systems have many applications in immunology and histochemistry. Interactions between avidin and biotin are remarkably strong with dissociation constants on the order of 10-15 M. With an antigen-antibody complex and a biotin-labeled antibody, colorimetric/fluorometric detection of the antigen can be performed using enzymes, fluorophore-labeled avidin or streptavidin. Maleimide biotins react with thiol compounds at a pH of 7-7.5. Maleimide reacts with the sulfhydryl group to create a thioether bond. Unlike other maleimide biotin reagents, Biotin-PE-maleimide can be solubilized in PBS at pH 7.4 to prepare a 2 mM solution without using an organic solvent. The reactivity of maleimide with sulfhydryl groups is higher than that of bromoacetamide, so the required concentration of maleimide biotin is much lower than that of bromoacetamide biotins. Stock solutions of Biotin-PE-maleimide and Biotin-PEAC5-maleimide in DMSO are stable for 1 year at -20°C.
