Nanopartz Antibody Functionalized Gold Nanoparticles

Nanopartz Gold Nanoparticles, conjugated specifically for in vitro applications, utilize the complete line of Accurate Spherical Gold Nanoparticles and Gold Nanorods functionalized via a number of different methods including absorption, short carbon covalent bridges, PEG, and our own proprietary invitro covalent polymer bridge - all to the most popular primary and secondary antibodies. Using our invitro covalent polymer bridge, this product is well known for its resistantance to temperature, salt, and pH, and for its exceptional loading capability. Using our in vivo covalent polymer bridge, this product is know for its long circulation times and it exceptional loading capacity. These conjugated particles can be used in a multitude of applications, including diagnostics, imaging, particularly in adverse environments. These particles are guaranteed not to aggregate. Every batch is completely characterized including size, monodispersity, aggregation, residual chemicals, and concentration. Typical volume is 1mL at a concentration of 50 OD. 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 antibody is measured. Please note products on this page require additional quotes as different antibodies incur different charges.

Spherical Gold Nanoparticles UV VIS

How much thickness does your proprietary in vitro polymer bridge add?

From 1-2nm.

What is the length of the different PEGs?

Go to PEG length.

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 solution 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

What is the shelf life if I never open the package and keep refrigerated?

Many years.

Should I store in the refrigerator?

Yes.

How do you size your gold nanoparticles? Does the size include the capping agent?

We use three methods to specify our gold nanoparticles; TEM, UV VIS, and DLS. Each has its own advantages and disadvantages, and we use a weighted system to take advantage of each methods strengths. In the end, we place the strongest weight to the TEM method, particularly since we use samples sizes greater than 50 particles for each lot.

Do you really provide a TEM for my specific lot?

Yes, and not just for 5-10 particles, rather 50-100 are standard.

Why are your small gold nanoparticles colored? I have seen 2nm particles on other website that look as clear as water.

All gold nanoparticles absorb and/or scatter. If you can't see them, then they probably aren't there.

What is OD?

Optical Density (OD) is measured by UV-VIS. An Optical Density OD=1 corresponds to a transmission of 10% through a 1cm cuvette. Optical Density is a nice unit to use since Optical Densities correlate linearly to concentration. So an Optical Density of 1.2 is equal to 1.2 times the concentration of a gold nanoparticle solution that has an Optical Density of 1. We use OD and concentration interchangingly as it is easier to refer to a solution of OD=1 rather than 2.35e12 nanoparticles. For all spheres up to 200nm, OD=1 does refer to 0.05mg/mL.

What is PDI?

PDI refers to polydispersity index and is equal to the standard deviation of the particle sizes divided by the average size.

How does your polymer bridge compare to PEG?

It is superior in its resistance to salt, pH, loading, and other chemicals.

"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."

The manufacturing method for these nanoparticles are based on our proprietary method. This family of products have resulted in more than 100 publications and is the cornerstone of our product line. Other covalent polymer bridges are available as well.

 

 

  Nanopartz™ Ab Conjugated Gold Nanoparticles Others
Stability (salt,pH,chemicals) High Medium
Monovalent option Yes No
Nonspecific binding Very low Medium
Sterilization Yes No

 

 

  • Covalent bonds insure specificity, stability, long shelf life
  • Buffer Stability - stable from pH 4-9
  • No sodium azide
  • No BSA
  • Polymer coating insures no aggregation in high salts, reduced nonspecific binding
  • Stable
  • Well Characterized
  • Customer can select buffer
  • Customer can select gold nanoparticle type, size and/or SPR
  • Loading of all ligands is optimized

Example part number is CAS11-10-488-Host Ab-Anti Reactivity-1KPEG-FC-PBS-50-1-CS-EP where:

CAS11 - Product family number for Secondary Antibody Conjugated Spherical Gold Nanoparticles. For Gold Nanorods, its CAS12 and so forth.

10 - Sphere diameter in nanometers. Other choices are 1.8 to 1500.

488 - Optional Fluorophore.
