Dojindo Molecular Technologies Inc -SulfoBiotics- Biotin-HPDP(WS) solution (500 μL) is a novel water-soluble biotin-labeling reagent that is modified from Biotin-HPDP, easy-to-use aqueous solution including 20 mmol/l Biotin-HPDP(WS).
Biotin-HPDP is a reagent widely used to introduce a biotin moiety to a sulfhydryl group of protein via a reversible disulfide bond via the Biotin switch method. This reagent is useful for affinity-purification of biotinylated proteins by using avidin-coated beads, because the disulfide bond can be cleaved by a reducing agent. However Biotin-HPDP has very low solubility in a solvent, and it is necessary to dissolve it by using an organic solvent such as DMSO or DMF. The preparation of this solution is time-consuming.Biotin-HPDP(WS) solution is a novel water-soluble biotin-labeling reagent that overcomes the problems of Biotin-HPDP by dramatically improving its solubility in water. Moreover, since it is a 20 mmol/L aqueous solution, no reagent dissolution operation is required. Dojindo offers various sulfur biology reagents. (https://www.dojindo.com/sulfur-biology/)
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.
