90nm Ni-NTA Gold Nanoparticles

When 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.

Gold 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.

The 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.

The 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.

The 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.

This mid-to-large nanoparticle size can be useful when stronger optical contrast or more particle surface area is desired.

For 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.

For 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.

Application areas

• Protein labeling and protein-nanoparticle conjugate preparation
• Binding and labeling of His-tagged proteins using Ni-NTA chemistry
• Assay development and comparison of nanoparticle size or surface chemistry
