Compared to the positive control (co-localization rate of 78.5±1.3% and Pearson's correlation coefficient of 0.82±0.01), LAMP1-GFP and Gold-BSA-Rhodamine showed comparable high co-localization in either non-infected cells (co-localization rate of 80.22±6.7% and Pearson's correlation coefficient of 0.85±0.02) or cells post infection (e.g., at 8 h p.i., co-localization rate of 79.7±3.5% and Pearson's correlation coefficient of 0.74±0.02). Here, LAMP1 is linked to infection.
