Study Title | Absolute quantification of plasma cytokines and metabolome reveals the glycylproline regulating antibody-fading in convalescent COVID-19 patients |
Study Summary | COVID-19 pandemic has caused tremendous costs worldwide and is still threatening public health in the “new normal”. The association between neutralizing antibody levels and metabolic alterations in convalescent patients with COVID-19 is still poorly understood. In the present work, we conducted absolutely quantitative approach to profile the metabolomes in the plasma of the ordinary convalescent patients with antibody (CA), the convalescents of rapidly faded antibodies (CO) as well as the healthy subjects. |

Treatment Summary: | We classified the convalescent patients into the CA and CO groups according to the results of the ELISA test of anti-SARS-CoV-2 IgG following the manufacturer’s instructions. Briefly, 100 μL of diluted plasma samples (1:100 to 1: 800 dilution) was added to pre-coated plates, and the plates were then incubated at 37°C for 1 h. After washing, 100 μL of horseradish peroxidase (HRP)-conjugated RBD protein of SARS-CoV-2 was added into each well, followed by 30 more min of incubation at 37°C. After washing, the OD value at 450 nm (A450) was determined. The cutoff for negative was calculated by summing 0.090 and the average A450 of negative-control. A sample was determined negative when its A450 was below this cutoff value. |
