Toolkit to Determine the Health and Activity of Antibody Functionalized Gold Nanoparticles

Nanopartz offers a number of toolkits that will help you assess the activity of your antibody functionalized gold nanoparticles. This toolkit utilizes the power of Nanopartz nanomagnets to selectively bind to healthy, functionalized antibodies on gold nanoparticles. The video below shows how this can be achieved in less than 30 seconds. The key to the product is the antigen loaded Nanopartz nanomagnets. Highly reactive, highly magnetic, and yet small enough to functionalize and then selectively magnetically separate only healthy antibody/gold nanoparticle conjugates in solution. Overall measurements are made using a simple UV VIS. This same method can be used to measure non specific binding as well.

Certifications

Every order comes with a Certification of Analysis that includes the following information. We use calibration 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 mass measurements

TEM (Phillips CM-100 100KV) for sizing

How long does it take to bind the antigen functionalized nanomagnets to the antibodies?

That depends on the antibody concentration.

How long does it take to pull the antibody/gold nanoparticle + antigen functionalized nanomagnet pairs out of solution.

That depends on the gold nanoparticle size.

Can I measure the non specific binding?

Yes.

The manufacturing method for these nanoparticles are based on our proprietary method. This invention allows the first use of a reducing agent to be used at room temperature. Unlike citrate which is only a reducing agent at the boiling temperature of water - thereby quickly making non-monodisperse magnetic nanoparticles, our reducing agent works by slowing building nanoparticles from seed, atom by atom, over the course of up to hours. The result is a highly monodisperse product with unrivaled spherical shapes. Monodispersity is important for efficient calculation.
