Coagulation curve analysis and immunogold staining of colloidal gold-labelled mAb. (A) The optimal pH value of gold particles and the concentration of mAb LK2-11a for stabilizing colloidal gold particles were determined by the coagulation curve analysis. The OD absorbance of each sample was determined at 580 nm. After the tracer (the mAb-gold complexes) was prepared, it was examined using transmission electron microscopy; (B) and stained by the goat anti-mouse IgG 6-nm gold conjugate (C).
