Cy5-Biotin，Cy7-Streptavidin

供應(yīng)Cy5-Biotin 1mg我公司供應(yīng)Cy5-Biotin試劑產(chǎn)品，如果有需要了解Cy5-Biotin試劑包裝、價(jià)格及貨期的請(qǐng)與我們聯(lián)系。Cy5-Biotin產(chǎn)品介紹：Cy5 Biotin can be used to quantitate available biotin-binding sites or the concentration of avidin or streptavidinCy5 Biotin is a heterobifunctional reagent containing a biotin moiety and a Cy5 group separated by a long-chain hydrophilic polyethylene glycol (PEG) spacer arm. Unlike Biotin-Fluorescein, whose absorbance and emission is strongly pH dependent, optical properties of Cy5-Biotin is completely pH independentReproducibility – absorbance and emission spectra of Biotin-Cy5 are pH independentSolubility – reagent easily dissolve in aqueous buffersExtended PEG3 Spacer – reduces aggregation, minimizes steric hindrance for affinity-binding to avidin or streptavidin供應(yīng)商：西安凱新生物科技有限公司

Cy3-Streptavidin，熒光標(biāo)記鏈霉親和素試劑，Cy3-labeled Streptavidin我公司供應(yīng)進(jìn)口熒光標(biāo)記鏈霉親和素試Cy3-Streptavidin，Cy5-Streptavidin，Cy5.5-Streptavidin和Cy7-Streptavidin試劑Cy3-Streptavidin熒光標(biāo)記鏈霉親和素試劑介紹：Fluorescent conjugates of streptavidin is a well-established detection tool for protein array, in-gel western, ELISA, and western blottingFluorescent conjugates comprises a biotin-binding protein (streptavidin) covalently attached to a fluorescent label. Streptavidin is a 66 kDa tetramer protein that can bind up to 4 molecules of biotin with extremely high affinity (Kd = 10-15 M). Fluorescent conjugates of streptavidin are commonly used for specific detection of a variety of biotin-labeled proteins, protein motifs, nucleic acids, and other molecules (for example, a biotinylated primary antibody bound to a protein target can be detected with a fluorescently labeled streptavidin). Strategies similar to this are used in many detection protocols including western blots, flow cytometry, imaging, microscopy, and microplate assays. Fluorescent dye streptavidin conjugates are supplied in 1 mL volumes at 1 mg/mL solution.High performance – optimized dye-protein ratios ensure high signal-to-noise, and low backgroundIntense fluorescence – bright emission offers great sensitivityNarrow emission spectra – enables sensitive, multi-color analysisConsistent performance – minimal lot-to-lot variation reduces the need for assay optimization如果有需要了解Cy3-Streptavidin，Cy5-Streptavidin，Cy5.5-Streptavidin和Cy7-Streptavidin熒光標(biāo)記鏈霉親和素試劑，請(qǐng)致電我們公司咨詢。供應(yīng)商：西安凱新生物科技有限公司HRP Streptavidin 1mg我公司提供HRP Streptavidin本辣根過氧化物酶標(biāo)記鏈霉親和素試劑，如果有需要可以跟我們公司聯(lián)系。HRP Streptavidin產(chǎn)品介紹：HRP-Conjugated Streptavidin consists of streptavidin protein, that is covalently conjugated to horseradish peroxidase (HRP) enzyme.HRP Streptavidin is a well-established detection tool for ELISA, chemiluminescence detection, and western blot analysis as well as immunohistochemistry and immunocytochemistry. Using biotinylated primary or secondary intermediates and peroxidase-labeled streptavidin, antigens can be localized in histological sections, cytospin preparations, or smears. In addition, sensitive detection systems for a variety of solid-phase assays utilizing microtitration plates or nitrocellulose have been developed using this conjugate.如果有需要了解HRP Streptavidin本辣根過氧化物酶標(biāo)記鏈霉親和素試劑，請(qǐng)致電我們公司咨詢。供應(yīng)商：西安凱新生物科技有限公司
