Biotinylation Kits & Reagents
Solulink is the inventor and manufacturer of ChromaLink Biotin, the most advanced and intelligent biotinylation reagent on the planet. It is the only biotinylation reagent with a built-in feature that tells the user how many biotins are on the antibody, protein or peptide with just a simple UV scan.
Featured Product: ChromaLink™ Biotin Labeling Kit
Biotinylate & Quantify Antibody Labeling with 1 Reagent
ChromaLink Biotin links traceable biotins on any amine-containing biomolecule or surface. The kit allows for the simple and direct UV quantification of total incorporated biotin on antibodies and other proteins.
Technology
ChromaLink Biotin is the most advanced protein biotinylation reagent available. It features a water-soluble sulfo-succinimidyl ester functional group (a), which modifies protein lysine residues in an aqueous buffer. The linker is UV-traceable (b), and absorbs at 354 nm. This UV-signature permits rapid quantification of incorporated biotin (c), by means of non- destructive measurement (A280/A354 nm). The linker possesses an extended PEG3 spacer (d), which helps preserve and maintain streptavidin/biotin affinity while enhancing antibody solubility.

Quantitation is Built Into the Reagent
By simply measuring the 280 and 354 of a modified protein, the concentration and number of biotins incorporated per protein can be determined directly.
