Cytodiagnostics provides custom conjugation of full length antibodies, antibody fragments (e.g. Fab', F(ab')2
, scFv), enzymes and other proteins to our gold nanoparticles, silver nanoparticles, and gold nanourchins with a wide range of available sizes (up to 100nm in diameter).
Conjugation can either be done through direct attachment to the nanoparticle surface (standard), or covalently through a linker, depending on customer need.
To be able to perform your custom conjugation we require 2-3 mg of purified lyophilized protein. If you want us to source your protein of antibody we would be glad to assist.
A successful conjugation would result in a typical yield of 10ml* of your protein gold, silver nanoparticle or gold urchin conjugate at an optical density of 3 (OD=3). This amount is generally sufficient to probe 10-15 PVDF or nitrocellulose membranes or more using 15ml of a 1:15 diluted conjugate per strip as a starting point.
