2 nm Immuno Gold Reagents (2)
AURION 2nm Immuno Gold Reagents are prepared using a monodisperse size population of 2nm gold nanoparticles. Due to its small gold nanoparticle size, labeling density with AURION 2nm Immuno Gold Reagents is significantly higher compared to particle density obtained with Conventional Immuno Gold Reagents. This makes the conjugate especially suited for detection of low copy numbers of antigen. Read more about AURION 2 nm Immuno Gold Reagents. -
Ultra Small Immuno Gold Reagents (28)
Aurion Ultra Small Immunogold Reagents are prepared with subnanometer gold particles. These particles have far less influence on the adsorbed antibodies or detecting molecules, and consequently the conjugates behave as though they are uncoupled. In conjunction with the highly efficient and easy-to-use R-Gent SE-LM and SE-EM silver enhancement reagents, the Ultra Small Immunogold Reagents are the best choice for any application.

Conventional Immuno Gold Reagents (27)
Conventional Immunogold Reagents are available in four size classes. The monodisperse size population makes the conjugates suited for multiple labeling with no overlap. The Conventional Immunogold Reagents are the classical conjugates in immuno electron microscopy; they are a good choice when the antigen is abundant and the accessibility of the antigen is relatively good.

AURION BSA-c (1)
In the blocking step, hydrophobic moieties causing “stickiness” in the specimen surface are rendered hydrophilic to minimize background. Nevertheless, the more dynamic charge-based interaction between the specimen surface and immunoreagents also needs to be controlled in order to eliminate background. Aurion has developed BSA-c™ , a unique incubation buffer additive with an unparalleled ability to effectively prevent charge based background. BSA-c™ is prepared by acetylation of bovine serum albumin (BSA). Polycationic sites in the specimen interact readily with negatively charged acetylated BSA molecules. This significantly reduces the risk that such sites might bind negatively-charged immunoreagents and immunogold conjugates and thus reduces the risk of background. Read more about AURION BSA-c -
AURION Blocking Reagents (12)
The signal-to-noise ratio determines the quality of any detection experiment. This ratio is in principle determined by the characteristics of specimen and detection reagents. With adequate blocking and incubation media, background reactions are minimized whereas specific reactions are not hampered. Read more about AURION Blocking Reagents -
Silver Enhancement Reagents (3)
The Immunogold Silver Staining technique (IGSS) finds application both at the electron microscope and the light microscope level. In addition the technique is used to identify proteins or nucleic acids after blotting. Light microscopical and macroscopical visualization of the latent gold signal requires an enhancement system that renders a high contrast signal. Light insensitivity and negligible autonucleation are required for ease of handling and low background. Read more about Silver Enhancement Reagents -
AURION Gold Nanoparticles (3)
Gold Nanoparticles - Gold Sols - have been developed for conjugate preparation via the classic direct adsorption method. AURION Gold Nanoparticles - Carboxyl Functionalized - have been developed to facilitate conjugating gold nanoparticles to molecules that cannot be conjugated via the classic direct adsorption method. The product is especially suited for covalent conjugation of small ligands. Read more about AURION Gold Nanoparticles... -
AURION Gold Tracers (4)
Aurion Anionic Gold Tracers are used to visualize charged moieties in specimens. They bind to polycationic moieties (basic proteins e.g. histones). “Neutral” BSA coated gold tracers are useful for detecting open connections and tissue damage. Under proper conditions and with suitable microscopical techniques the tracers can also be used to follow cellular events in time. Read more about AURION Gold Tracers -
Miscellaneous (1)
Col-Aurion is a colloidal gold particle based total protein stain, developed for the sensitive staining of electrophoretically separated protein bands on nitrocellulose or PVDF™ blotting membranes. Colloidal gold particles accumulate at the site of the protein bands on the membrane, generating an intense dark red staining pattern. The total protein stain assists in assessing immunoblotting results and to evaluate the effectivity of the blotting procedure. Read more about Col-Aurion
