Parameters for protein adsorption on gold nanoparticles.

Protein MW, kD 1/MW, kD−1 Kd(1), nM Kd(2), nM N
IgG 150 0.00667 4 30 52
BSA 66 0.01515 6 76 90
Protein G 26 0.03846 10 175 500
STI 20 0.05 15 100 550

Kd(1) and Kd(2) are the equilibrium dissociation constants for sections of the Scatchard graph significantly below the saturation value, and close to the saturation value, respectively; N is the maximum number of binding sites; BSA: bovine serum albumin; STI: Kunitz-type soybean trypsin inhibitor; protein G: recombinant streptococcal protein G; IgG: human immunoglobulin G.
