Fig. 3From: Amine-Aldehyde Chemical Conjugation on a Potassium Hydroxide-Treated Polystyrene ELISA Surface for Nanosensing an HIV-p24 Antigena Intact HIV structure. The p24 antigen is indicated. b The optimization of APTES and GLU. APTES (0.5, 1, and 2%) and GLU (1 and 2%) were used with different combinations to detect the constant concentration (250 nM) of HIV-p24 antigenBack to article page
