Desthiobiotin-NHS ester is an NHS-activated desthiobiotin reagent that reacts with primary amines to form stable amide bonds, enabling reversible affinity capture with streptavidin in labeling and bioconjugation workflows. Supplied as a dry powder with recommended low-temperature storage, it is used for protein labeling, biochemical assays, and metalloprotein probing.
- Reacts with primary amines to form stable amide bonds.
- Enables reversible streptavidin-based capture due to lower affinity than biotin.
- Suitable for protein labeling, bioconjugation, and biochemical assays.
- Supplied as a powder with recommended low-temperature storage.
- High purity for reliable conjugation performance.
Cayman Chemical Botn-HPDP 5mg
A sulfhydryl-reactive biotinylation reagent that forms a reversible disulfide linkage, used to label protein cysteines and other substrates that contain sulfhydryl groups; EAsily linked with target substrates at pH 6.5 to 7.5 in buffers such as PBS; disulfide linkage can be cleaved by reducing agents
