Product details:
Carboxyl Gold Nanoparticles (40nm, 40OD) (ab269942) are coated gold nanoparticles functionalized with carboxyl groups that allow the covalent conjugation of antibodies, using the water-soluble carbodiimide crosslinker EDC.
Unlike traditional EDC/NHS coupling used to activate carboxyl groups, Carboxyl Gold Nanoparticles (40nm, 40OD) (ab269942) are optimized for single step EDC covalent coupling without signs of aggregation. This eliminates the need for EDC/NHS pre-activation and washing steps associated with traditional conjugations.
This process is also significantly faster than standard methods, with conjugates ready to use in less than 35 minutes.
Carboxyl Gold Nanoparticles (40nm, 40OD) (ab269942) have a narrow size distribution, a uniform spherical shape and high batch-to-batch consistency:
Mean Diameter 36-44 nm
SD <4 nm
CV% <10%
Composition: 40nm carboxyl-gold 40 OD carboxyl gold nanoparticles
Size: 40 nm
Adsorption max: 530 nm
OD: 40.0
Particles per mL: 36 x 10
Volume: 1 mL and 5 mL
Buffer: 10 mM EPPS, pH 8.5
Benefits of Carboxyl Gold Nanoparticles (40nm, 40 OD):
