Description
Gold Nanoparticle : GNPS Series
SR produces and commercializes highly spherical and stable citrate-stabilized gold colloids specifically adapted to lateral flow test format. Their unique sphericity combined with their size homogeneity and their highly contrasting ruby red color make SR Gold nanoparticle ideal for the development of rapid tests showing high sensitivity and precision.
Why Choose SR Bioera Gold
- High Sensitivity
SR BIOERA highly spherical gold nanoparticles do not contain sharp edges particles reducing their aggregation rate and maximizing the contact surface available to immobilize a high number of antibodies. High sphericity means that all antibodies interacting with the gold surface are in the same environment with very limited steric hindrance. This makes for favorable association kinetics between antibodies and their corresponding antigen.
- High Precision
SR BIOERA Gold colloids have the advantage to only present highly spherical and monodisperse particles with no odd shapes (e.g., triangles, hexagons…). All particles have the same size and morphology, so they will not bring any additional variability to your diagnostic assay.
- Economy
Using SR BIOERA Gold, you will be sure that all antibodies immobilized on colloidal gold will remain accessible for antigen binding. Using less costly antibody will allow substantial economies. In addition, our high-scale manufacturing units ensure you to benefit from highly competitive pricing while offering improved quality gold particles.
- Stability
Considering the excellent monodispersity and the truly spherical shape of our gold nanoparticles, our Gold offers unique shelf life of 24 months.
- High-Contrast
Well-dispersed and stable gold nanospheres give ruby red color to the colloidal gold suspension. This color, synonym of high-quality gold, reveals with high contrast test and control lines on nitrocellulose membranes.
- Flexibility
SR BIOERA Gold particles are available in different sizes for a maximum of flexibility. Single batch of gold nanoparticles are available at volumes exceeding 100 liters for reduced hands-on time linked to new batch implementation.
