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.

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/)
Biotium Tyramide Amplification Kit with HRP Streptavidin and CF640R Tyramide
Tyramide amplification, sometimes called Catalyzed Reporter Deposition (CARD), is an enzyme-mediated detection method that uses the catalytic activity of horseradish peroxidase (HRP) to generate high density labeling of a target protein or nucleic acid sequence in situ. The tyramide amplification method has been reported to increase the sensitivity by up to 100-fold compared to the conventional avidin-biotinylated complex procedure. The kit contains HRP streptavidin CF640R dye tyramide. The dye has an excitation/emission of 642/662 nm. The kit contains sufficient reagent for 50-150 slides.
Santa Cruz Biotechnology Chromeo™ P503 | 1mg
Chromeo™ P503 detects proteins and peptides by exhibiting a color change from blue to red. After binding to primary amines, it undergos a large shortwave spectral shift of more than 100nm that is visible to the naked eye. There is also a large increase in quantum yield that changes the non- or only weakly fluorescent dye into a bright fluorescent conjugate. The shift of the absorption & emission bands together with the increased fluorescence quantum yield effectively eliminates background from any unbound dye. In addition, because unbound the pyrylium dye is hydrolyzed during the labeling procedure, there is no need for purification following the simple one-step, room-temperature incubation. The labeled protein is ready to use immediately, and any possible background from the unbound dye is eliminated. Due to the unique conjugation mechanism, proteins labeled with Py-Dyes maintain their native charge and isoelectric point.
