T48 | 5-81 | Sentence | denotes | Reference Samples and Tests Chosen for Evaluation of Immunoassay Performance |
T49 | 82-193 | Sentence | denotes | Thirty-seven serum samples were obtained from 26 outpatient patients with a PCR-confirmed SARS-CoV-2 infection. |
T50 | 194-422 | Sentence | denotes | Blood was drawn between four and 60 days (median 19 days) after a positive real-time RT-PCR result in which parts of the SARS-CoV-2 E or N genes [18] were detected in oropharyngeal swabs with a cycle threshold ≤35 (median 26.8). |
T51 | 423-491 | Sentence | denotes | Serum was obtained from the blood and stored at −20 °C until tested. |
T52 | 492-672 | Sentence | denotes | These sera are likely to contain SARS-CoV-2 IgG/total antibodies and, therefore, were considered to determine the serological assay sensitivities (as previously suggested by [19]). |
T53 | 673-869 | Sentence | denotes | This variant of the sensitivity calculation only took into account whether a SARS-CoV-2-infected patient was reactive at all, regardless of when this reactivity was developed (reference method 1). |
T54 | 870-1000 | Sentence | denotes | A plaque reduction neutralization assay (PRNT) using a SARS-CoV-2 isolate designated as Kiel M16502/2020 and Vero cells (order no. |
T55 | 1001-1135 | Sentence | denotes | 605372, CLS Cell Lines Service GmbH, Eppelheim, Germany) was included as a further reference for the calculation of the sensitivities. |
T56 | 1136-1196 | Sentence | denotes | All sera classified as reactive in the PRNT were considered. |
T57 | 1197-1251 | Sentence | denotes | This also covered follow-up sera (reference method 2). |
T58 | 1252-1379 | Sentence | denotes | Testing was done under biosafety level 3 conditions and was in accordance to previous reports [20,21] with minor modifications. |
T59 | 1380-1475 | Sentence | denotes | One to two days before infection, 1.0 × 105 cells were seeded into each well of 48-well plates. |
T60 | 1476-1561 | Sentence | denotes | These were then incubated under standard conditions until the cells became confluent. |
T61 | 1562-1921 | Sentence | denotes | Directly prior to the PRNT, patient sera were heat-inactivated at 56 °C for 30 min and then diluted from 1:10 to 1:1280 in cell culture medium consisting of Dulbecco’s modified Eagle’s medium (DMEM) (Bio&SELL GmbH, Feucht, Germany) supplemented with 3.7 g/L NaHCO3, 4.5 g/L glucose, 2 mM L-glutamine, and 1% (v/v) Penicillin/Streptomycin/Fungi-Mix (Bio&SELL). |
T62 | 1922-2101 | Sentence | denotes | A serum dilution series was made by mixing 50 µL of each dilution step with 50 µL virus suspension containing 100 plaque-forming units, followed by an incubation for 1 h at 37 °C. |
T63 | 2102-2289 | Sentence | denotes | The cells were washed with phosphate-buffered saline (Bio&SELL), inoculated with 100 μL of these virus serum dilutions, and incubated for one hour at room temperature on a rocking shaker. |
T64 | 2290-2448 | Sentence | denotes | Then, 100 µL of the cell culture medium supplemented with 20% (v/v) fetal calf serum (FCS) was added to each well to achieve a FCS concentration of 10% (v/v). |
T65 | 2449-2640 | Sentence | denotes | After four to five days, cells were fixed with 4% (w/v) paraformaldehyde in phosphate-buffered saline and stained with an aqueous solution of 0.1% (w/v) crystal violet and 20% (v/v) methanol. |
T66 | 2641-2682 | Sentence | denotes | The stained plates were photo-documented. |
T67 | 2683-2816 | Sentence | denotes | All dilution steps were tested in quadruplicates, and plaque formation was compared to an untreated cell control and a virus control. |
T68 | 2817-2988 | Sentence | denotes | A serum dilution >1:10, which prevented plaque formation in at least 50% of the wells compared to the virus control, was classified as reactive and probably as protective. |
T69 | 2989-3047 | Sentence | denotes | The reciprocal titers were used to visualize the kinetics. |
T70 | 3048-3153 | Sentence | denotes | If an exact titer could not be given, a geometric mean value was calculated from the two adjacent titers. |
T71 | 3154-3305 | Sentence | denotes | For the calculation of assay specificities, 100 archived sera collected during the summer 2018 (N = 50) and during winter 2018/2019 (N = 50) were used. |
T72 | 3306-3372 | Sentence | denotes | None of these sera were expected to contain SARS-CoV-2 antibodies. |
T73 | 3373-3480 | Sentence | denotes | The inclusion of such pre-pandemic sera for the demonstration of specificity was previously suggested [19]. |
