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-PEG4-acid | >98% | 461.55 | 25 MG
Desthiobiotin-PEG4-acid is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs. PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
- Used as a PEG-based PROTAC linker
- Useful in the synthesis of PROTACs
- Enables selective degradation of target proteins

Medchemexpress LLC Desthiobiotin-NHS ester | 80750-24-9 | MFCD08062086 | 98.0% | 311.33 g/mol | C14H21N3O5 | 25 MG
Desthiobiotin-NHS ester is an amine-reactive bioconjugation reagent that couples desthiobiotin to primary amines via an N-hydroxysuccinimide (NHS) ester to form stable amide bonds. It is used for protein labeling, affinity purification, and biochemical assays where reversible streptavidin binding is desired.
- Reacts with primary amines to form stable amide bonds.
- Desthiobiotin tag enables reversible streptavidin binding for gentle elution.
- High purity (98.0%) supports consistent labeling performance.
- Available in small-scale quantities for research use, including 25 mg.
- Solid, white to off-white appearance for easy handling and storage.
- Powder stable at -20°C for extended shelf life; solutions should be stored cold.
Medchemexpress LLC Desthiobiotin-NHS ester | 80750-24-9 | MFCD08062086 | >98.0% | 311.33 | C14H21N3O5 | 1 G
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.
