Profile: Lumiprobe Corporation is a manufacturer of fluorescent dyes, and phosphoramidites for oligonucleotide synthesis. We offer advanced chemicals for life science research, and diagnostics. Pyrene is polyaromatic hydrocarbon containing four fused rings. This reagent contains terminal alkyne group. We offer acetylenic amidite for the incorporation of acetylene groups into oligos. Azido ester is designed for the conversion of proteins, peptides, amino-DNA, and other amines. Biotin azide is a derivative of biotin (vitamin H) covalently bond with azide group. This reagent allows labeling of various alkynylated molecules (such as DNA, oligonucleotides, and proteins) with biotin. Biotin binding to avidin or streptavidin can be used in downstream affinity applications for the isolation of biotinylated molecules or their binding with streptavidin conjugates. This structure of biotin azide features long hydrophilic linker which separates biotin residue from the target molecule for efficient binding with streptavidin. Its linker (PEG) also enhances aquous solubility to facilitate conjugation. Cyanine alkyne is non water-soluble. However, when used with organic co-solvent (DMSO or DMF), this dye can be efficiently attached to water-soluble molecules such as proteins, or peptides.
