Biotin is a water-soluble B-complex vitamin, also known as vitamin B7 or vitamin H. It binds to the biotin-binding pockets of streptavidin, Strep-Tactin, and Strep-TactinXT with different affinities. As a result, it allows the efficient elution of Strep-tagII or Twin-Strep-tag fusion proteins from Strep-TactinXT, while maintaining the reusability of the resin. It can be used for preparation of Strep-TactinXT elution buffer, Buffer BXT. In addition, biotin can be used for elution of biotinylated proteins from Strep-Tactin, where it binds irreversibly to the resin. Hence, Strep-Tactin cannot be regenerated in this kind of application.

Apexbio Technology LLC Sulfo-NHS-SS-11-Biotin 1g
Sulfo-NHS-SS-11-Biotin is an amine-reactive water-soluble biotinylation reagent containing an N-hydroxysulfosuccinimide (Sulfo-NHS) active ester group and a cleavable disulfide bond The Sulfo-NHS moiety reacts specifically with primary amines in proteins peptides or other biomolecules forming stable amide linkages This reagent introduces a disulfide-containing spacer arm enabling subsequent selective cleavage under reducing conditions for release of biotinylated molecules It is commonly employed in affinity chromatography immunoprecipitation experiments cell surface protein labeling and target identification allowing isolation purification or detection of biomolecules through streptavidin or avidin affinity interactions
Apexbio Technology LLC Cy3 Bis NHS ester 25mg
Cy3 Bis NHS ester is a water-soluble fluorescent labeling reagent containing two amine-reactive NHS ester groups on a single dye molecule This compound specifically reacts with primary amines such as lysine residues on proteins or amine-modified nucleic acids enabling covalent fluorescent conjugation Upon formation of stable amide bonds with target molecules Cy3 fluorescence can be detected with standard fluorescence instruments exhibiting excitation at approximately 550 nm and emission near 570 nm Typical applications encompass labeling proteins peptides antibodies nucleic acids and other amine-containing biomolecules for fluorescence microscopy flow cytometry and biochemical assays as well as single-molecule fluorescence resonance energy transfer (FRET) studies
