Conjugated Nanopartz™ Gold Nanoparticles

Nanopartz™ Gold Nanoparticles, conjugated specifically for in vitro applications, utilize the complete line of Accurate™ Spherical Gold Nanoparticles, Nanorods, Microgold™, Gold Nanowires, and Plasmonic Fluorophores™ conjugated via a covalent polymer bridge to the most popular in vitro terminations including amine, biotin, carboxyl, methyl, maleimide, neutravidin, nhs, streptavidin, and secondary antibody conjugations. These particles may also be conjugated to customer defined antibodies, peptides, oligos, and more. Most importantly, Nanopartz™ posseses the proprietary technology to bind to almost any location of the target. For instance, in binding to antibodies, not only does Nanopartz™ conjugate to the antibody, but can to specific sections of the antibody. This ability to covalently conjugate to specific locations ensures the activity of the target is not compromised. These conjugated particles can be used in brightfield, darkfield, fluorescence, and other imaging modes; and ELISA, lateral flow, and other assays. Every batch is completely characterized including size, monodispersity, aggregation, residual chemicals, and concentration. A Certificate of Analysis (COA) is provided for every order exhibiting TEM and UV-VIS images and data, as well as DLS data. In all cases, the loading of the target is determined.

Certifications

This product is manufactured using our audited ISO 9000/2001 quality control system. Every order comes with a Certification of Analysis that includes the following information. We use NIST traceable:

UV-VIS (Agilent 8453) for extinction and concentration measurements

NIR (Cary 500) for NIR extinction and concentration measurements

DLS (Malvern Nano ZS) for zeta potential measurement

ICP-MS (Varian 820-MS) for gold mass measurements

TEM (Phillips CM-100 100KV) for sizing

Detailed Specifications

For detailed specifications, please refer to the product family pages for those products. The coating compounds adds an unmeasurable thickness to the particles as the PDI of the particles is greater than the thickness of the polymer.

 

These gold nanoparticles exhibit extinctions from 500nm to 2100nm, perfect for labeling in dark field, bright field, and fluorescence microscopy applications. These gold nanoparticles come with a wide variety of covalent conjugations, specifically suited for in-vitro applications. They are resistant to high salt concentrations, and a wide variety of pHs (4-9). The customer is given the opportunity to select from a variety of buffers, and may request custom conjugations to specific antibodies. Nanopartz possesses technologies that allow for the "site specific conjugation" to antibodies, thereby keeping the ligand active for further activity. Customer has a choice for radiation sterilization (no sodium azide is used) certification and endotoxin free products.

How much thickness does your proprietary capping agent add?

It is less than the variablility of the size of the nanoparticles themselves, so it is unmeasurable.

How do I determine the concentration of the product?

Simply divide the number of nanoparticles (nps) found on the included COA by the amount of solvent you add.

Why do you sell your rods as OD-mLs and what does this mean?

This is because unlike spherical gold nanoparticles, the conversion from OD to mg is not linear with nanorod diameter. Consequently, for the same OD, the weight of the nanorods increases with diameter. 50 OD-mLs means that if you resuspend the material in 1mL of solvent, you will have an absorption of OD50 through a 1mL optical path.

Can I resuspend in water?

Yes

Can I suspend in silicon oil?

No

Will the SPR wavelength shift with different solvents?

The SPR is a function of the index of refraction of the host solvent in which the nanoparticles are suspended. Nanorods are the most sensitive and are therefore a great tool for measuring the index of refraction of the host.

What is the shelf life if I never open the package?

1 year.

Should I store in the refrigerator?

Yes.

"We have looked at many different gold nanoparticles samples from Nanopartz including spheres, rods, and microrods using single particle spectroscopy techniques and are extremely happy with the quality of the samples and the service provided by Nanopartz."
