製品名20nm Gold Nanoparticles (1 OD)
20nm Gold Nanoparticles (1 OD) (ab269935) is an aqueous suspension of spherical metallic nanoparticles manufactured to the highest standard to ensure:
- Uniform spherical shape
- Narrow size distribution: 20nm ± 2nm, <10% CV
- Ultra high quality
- Batch to batch consistency
- High efficiency antibody binding for maximum sensitivity
- Available at high concentrations to simplify assay development.
This product is manufactured by Expedeon, an Abcam company. It was previously called 20nm Gold Nanoparticles (1 OD). Expedeon product code 3201-0010 is the same as the 10 mL size of this product and code 3201-0100 is the same as the 100 mL size.
Our colloidal Gold Nanoparticles are suspended in citrate buffer and are suitable for:
- Protein adsorption
- Oligonucleotide adsorption
- Surface modifications.
Narrow size distribution and consistent shape is important and preferable for most applications.
A consistent, spherical shape means that particles are less prone to aggregation, which can be a problem associated with gold nanoparticles. Furthermore uniform shape ensures consistent binding of antibodies, ensuring reliable assay results.
保存方法Shipped at Room Temperature. Store at +4°C. Do Not Freeze.
