Product details:
Gold nanoparticles at Abcam have a proprietary surface coating that can withstand the most extreme conditions (e.g. 2.5 M NaOH at 70°C for 2 hours), making our Gold nanoparticles an ideal reagent for a wide range of applications.
Our Gold streptavidin conjugates share the stability attributes of the core nanoparticle. Furthermore, since the streptavidin is covalently bound to the surface coating of the gold nanoparticle it is unable to desorb, which is a major problem faced by competing products whereby the streptavidin is directly attached to the metal. Our Gold Streptavidin binds with high affinity to biotinylated molecules.
Notes:
This product is manufactured by Expedeon, an Abcam company. It was previously called 20nm InnovaCoat
GOLD (10 OD) Streptavidin Conjugate. Expedeon product code 251-0200 is the same as the 200 μL size of this product and code 251-1000 is the same as the 1 mL size.
