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
Bachem D-Biotinyl-OSu
D-Biotinyl-OSu, 35013-72-0, C14H19N3O5S, Mr 341.39, 1g. BNHS, Biotin-NHS. The activated biotin derivative Biotin-OSu is used for labeling the amino groups of amino acids, peptides, and proteins. When conducting the biotinylation at pH 6.5, N-terminal amino groups can be selectively tagged in the presence of lysine.
Aat Bioquest Texas Red® cadaverine *Single Isomer*
Texas Red® cadaverine reacts with carbonyl compounds such as aldehyde, ketones and acids to give bright red fluorescent conjugates. It is widely used for labeling glycoproteins and carbohydrates through reductive amination.
Apexbio Technology LLC Sulfo-NHS-SS-11-Biotin,100mg
Sulfo-NHS-SS-11-biotin is a long-chain cleavable amine-reactive biotinylation reagent. The presence of the negatively charged sulfonate group in the chemical structure of sulfo-NHS-SS-11-biotin makes it a water-soluble biotinylation reagent that can be directly added to aqueous reactions without prior dissolution of organic solvents. Although no prior dissolution is required, an aqueous stock solution of sulfo-NHS-SS-11-biotin must be prepared rapidly and used immediately in case of the occurrence of hydrolysis of the active ester. Sulfo-NHS-SS-11-biotin has been used to react with amine-containing proteins and other molecules forming a complex which further interacts with avidin or streptavidin probes and to purify targeted molecules using affinity chromatography on a column of immobilized avidin or streptavidin. Other sizes are also available. Please inqury us for quote.

LICOR IRDye QC-1 NHS Ester (5.0 mg)
IRDye QC-1 is the first non-fluorescent (dark) quencher compatible with a wide range of visible and near-infrared fluorophores (~500-800 nm). It has the widest available quenching range, so you do not need to carefully match the donor's fluorescence spectrum with the acceptor's absorbance. IRDye QC-1 NHS ester can be used for FRET (fluorescence resonance energy transfer) applications such as protease assays. Recently, it has been paired with IRDye 800CW in optoacoustic studies.
