Meet the newest addition to our family of gold nanoparticle labeling reagents.
Now available: our 5 nm Nanogold® labeling reagents bring the same covalent labeling and conjugation reactions available with our 1.4 nm Nanogold® labeling reagents.
Make any molecule a gold probe:
- Antibodies
- Proteins
- Peptides
- Oligonucleotides - DNA, RNA and PNA
- Small molecules
|
- Hormones
- Surfaces
- Nanostructured materials
- ...and many more

VivoVist™: The Ultimate Micro CT Contrast Agent |
| |
| Best Performance · Best Value · Best Price
|
| |
- VivoVist™ provides approximately 3-4 times higher contrast than competing commercial microCT contrast agents
- Long blood half-life of 14 hrs. Enables extended imaging times and longer diffusion into tumors and other features of interest
- Lowest price - affordable rat imaging! Less than two vials provides good contrast in a 250 g rat.
- Low toxicity (4 g/kg is well-tolerated). Produce super-high contrst in fine structures and accelerate loading of tumors
- Low osmolality, even at high concentrations - minimal metabolic disruption
- Low viscosity: easy to inject into small mouse tail vein blood vessels
- Image with MicroCT, clinical CT, planar X-ray, or mammography units - flexibility for any desired instrument configuration
- Enhances radiotherapy - higher X-ray dose to tumors and other targets

Updates
Our mission at Nanoprobes is to harness chemistry, biology and nanotechnology to engineer the most sensitive reagents and nanotechnology for detecting, locating and visualizing biological molecules.
Our unique gold nanoparticle labeling technology uses chemically cross-linked metal clusters and nanoparticles as labels.
Unlike conventional immunogold probes, in which colloidal gold particles are electrostatically adsorbed to antibodies and proteins, our gold nanoparticle labels are uncharged molecules which are cross-linked to specific sites on biomolecules. This gives our nanogold probes greater range and versatility than colloidal gold.
Our labels can be attached to any molecule with a reactive group -- proteins, peptides, oligonucleotides, small molecules and lipids -- for detection and localization. Other labels can be combined with our gold particle labels; our unique FluoroNanogold probes combine Nanogold® and fluorescein into a single probe for imaging a specimen both by fluorescence and electron microscopy. Our gold nanoparticles, including our Nanogold™ conjugates, and Nanogold™ labeling reagents, are formulated for use with electron microscopy (tem) as well as light microscopy, immunolabeling, x-ray contrast for EM, angiography, mammography and microCT, and for correlative and fluorescence microscopy imaging.
New probes can be engineered based on any fragment of a naturally occurring biomolecule, and the label can be positioned away from the binding site so it does not interfere with binding.
Our Nanogold® probes have been cited in over 250 publications, and are used in the laboratories of several Nobel Laureates.
It's all about creating better tools and finding innovative solutions, so that research and treatments can move ahead.
Drop us a line and let us know what you're working on. We'll be glad to help.
