biotechrabbit™ Tris-NTA Biotin for high-affinity His-tag binding.
His-tags are one of the most commonly used tags for protein expression analysis. Conventional metal ion chelators, such as nitrilotriacetic acid (NTA) and iminodiacetic acid (IDA), bind His-tags with low affinities in the range of 10 µM. The biotechrabbit Tris-NTA complexes three NTA groups that together bind a 6xHis-tag with an affinity that is four orders of magnitude higher (1 nM) than is possible with conventional chelators. The binding of His-tags is stoichiometric, and single-molecule detection is possible. Binding is reversible: bound His-tags can be released with imidazole or ethylenediaminetetraacetic acid (EDTA).
biotechrabbit Tris-NTA is available in amino-group-conjugated and biotinylated forms and can be used in a large range of applications, including protein detection and marking, protein, lipid or cell coupling to surfaces, protein purification and reversible protein modification.
