Apexbio Technology LLC Sulfo-NHS-LC-D-Desthiobiotin 1mg
Sulfo-NHS-LC-D-Desthiobiotin is a sulfonated amine-reactive labeling reagent targeting primary amines on proteins or peptides It is designed to covalently label cell-surface proteins by reacting with lysine residues or protein N-termini thereby enabling selective modification of these proteins Sulfo-NHS-LC-D-Desthiobiotin exerts its biological activity primarily through covalent reaction with primary amines via its activated Sulfo-NHS ester Due to its membrane-impermeable negatively charged sulfonate group it selectively labels cell-surface proteins without entering intact cells Based on these chemical properties Sulfo-NHS-LC-D-Desthiobiotin holds research potential in affinity purification biotin-streptavidin interaction assays selective enrichment and analytical workflows involving reversible labeling of surface proteins

Medchemexpress LLC Desthiobiotin-NHS ester | 80750-24-9 | MFCD08062086 | 98.0% | 311.33 g/mol | C14H21N3O5 | 100 MG
Desthiobiotin-NHS ester is a desthiobiotin analog bearing an N-hydroxysuccinimide (NHS) ester that selectively reacts with primary amines to form stable amide bonds. The desthiobiotin moiety binds streptavidin with lower affinity than biotin, allowing reversible affinity capture and mild elution, making it useful for labeling, enrichment, and probe development in biochemical assays.
- Selective labeling of primary amines.
- Enables reversible streptavidin-based affinity capture.
- Forms stable amide bonds for durable conjugation.
- Suitable for protein labeling and pull-down assays.
- Available in multiple package sizes for research scalability.
