To explore this possibility, we processed doxycycline-treated HTet1/SW1 and HTet1/SD614G for immunofluorescence microscopy (IFM) using the human polyclonal anti-spike antibodies present in COVID-19 patient plasmas, together with antibodies specific for the Golgi marker GM130 (SARS spike is known to accumulate in the Golgi) (74). This evidence concerns the gene GOLGA2 and COVID-19.
