MAE C187/C287L Lab 8. Biomolecule Fluorescence Detection Procedures 1. Clean a SiO 2 /glass chip by DI water rinse. Blow to dry. 2. Prepare BSA and biotin-BSA solution in plastic tubes. 3. Put one droplet of BSA solution and three droplets of biotin-BSA on the chip. Incubate for 30 min. Rinse with DI water. 4. Prepare Streptavidin labeling solution (20ul Alexa 546-streptavidin conjugate stock solution dilute in PBS by a factor of 10) and control sample (Alexa 546- DNA). 5. Add prepared solutions to each spot as following:
