{"product_id":"90nm-ni-nta-gold-nanoparticles","title":"90nm Ni-NTA Gold Nanoparticles","description":"\u003cp\u003eWhen protein labeling, His-tag protein binding, and assay development require a well-defined nanoparticle reagent, the 90 nm Ni-NTA gold nanoparticles format helps procurement and lab teams identify the relevant material and functional configuration.\u003c\/p\u003e\n\u003cp\u003eGold nanoparticles are widely used as plasmonic labels and conjugation scaffolds because their optical response, surface chemistry and particle size can be matched to assay, imaging or sensor formats. The listed absorption maximum of 564 nm can help compare this size with related gold nanoparticle options.\u003c\/p\u003e\n\u003cp\u003eThe Ni-NTA surface is intended for binding proteins that carry a terminal 6x His tag. This makes the particle suitable for preparing His-tag protein probes and for assay development involving histidine-tagged targets.\u003c\/p\u003e\n\u003cp\u003eThe supplied description notes controlled particle sizing and dynamic light scattering assessment of size and monodispersity. That context is useful for assays where optical response, conjugate behavior or particle-size comparisons need to be reproducible.\u003c\/p\u003e\n\u003cp\u003eThe application profile includes protein labeling, His-tag protein binding, and assay development. These terms reflect the supported scientific workflows for this listing and help scientists compare related products by use case, not by material alone.\u003c\/p\u003e\n\u003cp\u003eThis mid-to-large nanoparticle size can be useful when stronger optical contrast or more particle surface area is desired.\u003c\/p\u003e\n\u003cp\u003eFor gold nanoparticle workflows, compare standard, stabilized, reactant-free, endotoxin-free and functionalized versions according to the application. The same size can behave differently depending on the surface chemistry and formulation.\u003c\/p\u003e\n\u003cp\u003eFor procurement and product selection, compare it with related nanoparticles by particle size, surface chemistry, formulation and listed application rather than treating all nanoparticles as interchangeable.\u003c\/p\u003e\n\u003ch3\u003eApplication areas\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eProtein labeling and protein-nanoparticle conjugate preparation\u003c\/li\u003e\n  \u003cli\u003eBinding and labeling of His-tagged proteins using Ni-NTA chemistry\u003c\/li\u003e\n  \u003cli\u003eAssay development and comparison of nanoparticle size or surface chemistry\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cytodiagnostics","offers":[{"title":"0.5 ml","offer_id":58053253824857,"sku":"CGNTA-90-25","price":255.0,"currency_code":"EUR","in_stock":true},{"title":"1 ml","offer_id":58053253857625,"sku":"CGNTA-90-50","price":445.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/1011\/0553\/files\/100nm-functionalized-gold-nanoparticles_c6888a28-cf0c-43cf-8a9e-cb8d894f5a0f.jpg?v=1778675473","url":"https:\/\/absource.de\/products\/90nm-ni-nta-gold-nanoparticles","provider":"Absource Diagnostics","version":"1.0","type":"link"}
