Product Overview:
Alkynyl-biotin is a form of biotin with a terminal alkyne group separated by two polyethylene glycol moieties. It is used to add biotin to other molecules bearing an azide group using a copper Cu(I)-catalyzed azide-alkyne cycloaddition reaction. Alkynyl-biotin has been used to add a biotin tag to a range of biochemicals, amino acids, proteins, and nucleotides that have been modified by the addition of an azide group.{33225,33226,33227} Alkynyl-biotin can also be used to capture sulfenic acid-modified proteins that have been tagged with the cell-permeable probe DAz-2 (Item No. 13382).{17444}

Cayman Chemical's mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.

Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.

Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.

Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
