StreptaClick® Precision is a modified streptavidin designed for precise stoichiometric 1:1 conjugations. Currently, StreptaClick® Precision is available with exactly one azide or exactly one DBCO (dibenzylcyclooctyne). StreptaClick® Precision also features a unique cis-divalent design for enhanced monovalent binding to biotinylated proteins. In addition, the conjugation site and the biotin binding region are on opposite sides of StreptaClick® Precision, minimizing the risk of conjugates interfering with biotin binding. This design makes StreptaClick® Precision ideal for attaching bulky molecules without sterically hindering biotin binding and without causing aggregation when mixed with biotinylated antibodies in solution.
Click-chemistry ready
StreptaClick® Precision is currently available with a single azide or DBCO group for either copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) or copper-free strain-promoted azide-alkyne cycloaddition (SPAAC) click chemistry.
For oligonucleotides, we strongly recommend SPAAC click chemistry (DBCO/azide).
Pre-conjugated, off-the-shelf
StreptaClick® Precision based, pre-conjugated products are also available. These include StreptaClick® Precision with a single 14 mer DNA oligonucleotide or a single bright fluorochrome (488 nm or 647 nm).
