Gold Nanoparticles, Streptavid

Synthesis and Characterization of Deoxyribonucleic Acid-Conjugated Gold Nanoparticles

Gold nanoparticles functionalized with thiol-modified single-stranded oligonucleotides are highly useful reagents for a variety of applications, ranging from materials science to bioanalytics. In this chapter, the preparation of citrate

Colloidal Gold/Streptavidin Methods

. This nonspecific binding has been attributed both to its high isoelectric point (PI = 10) and to the fact that the protein is glycosylated (3 , 4 ). Because of the problem of nonspecific binding of avidin, streptavidin has largely replaced avidin

Reverse Transfection Using Gold Nanoparticles

, we have found that the conjugation of gold nanoparticles (20 nm in particle size) to the pEGFP-N1/Jet–PEI complex resulted in an increase in the intensity of fluorescence of enhanced green fluorescent protein (EGFP) (based on the efficiency of transfection) from human mesenchymal
