Goat Anti-Rabbit IgG (40nm Gold, 10 OD)

Product details

The Goat Anti-Rabbit IgG antibody (GAR) is covalently conjugated to 40 nm Gold Nanoparticles which have a unique protective coating that can withstand most extreme conditions (e.g. 2.5 M NaOH at 70°C for >1 hour). The irreversible attachment does not allow the desorption of the antibody, which is a major problem with products in which the antibody is only passively adsorbed to the metal.

To exchange the conjugated antibody into a different buffer specific to your application, centrifuge the conjugate in a microfuge at 9,000 x g for 6 minutes. Carefully remove the supernatant, gently tap the pellet and add the preferred buffer. It is important to avoid substances that have a very high affinity for gold (e.g. thiols).

If an incubation of the conjugated Goat Anti-Rabbit IgG with the target antibody is performed, do not centrifuge the gold complex after this stage (an antibody titration is recommended).

The table below is just a guideline for possible applications:

This product is manufactured by Expedeon, an Abcam company. It was previously called 40nm InnovaCoat^® GOLD (10 OD) Goat Anti Rabbit IgG Conjugate. Expedeon product code 213-0200 is the same as the 200 μl size of this product and code 213-1000 is the same as the 1 mL size.

Concentration: 10 OD. The concentration for this product is expressed in OD units. This is based on the absorbance of gold nanoparticles at 530nm of a 1:10 diluted sample.
