Fig. 6From: Surface Functionalized Nanofibrillar Cellulose (NFC) Film as a Platform for Immunoassays and DiagnosticsCLSM intensity images of adsorbed FITC-stained antihuman IgG (100 μg/mL) in 10 mM phosphate buffer (pH 7.4) on unmodified NFC film (a) and EDC/NHS activated NFC-film (b). Both films were rinsed with 10 mM NaCl (pH 10) to remove electrostatically bound antibodies. Images are recorded using 848 V laser with constant imaging conditionsBack to article page
