Fig 4. NP selectivity in human serum (red) and in human serum + N. nigricollis venom (blue).

In the presence of serum alone, the NP favorably associates with proteins of varying molecular weights (Serum only corona band). A distinct change in the distribution and a new dominant molecular weight band (<15 kDa) in the N. nigricollis venom-containing corona band. Proteins that comprised this NP corona were identified via in gel digestion followed by proteomic identification.
