IHC (Immunohistochemistry) (Figure 11 IHC Validation of SARS-CoV2 Spike in COVID-19 Patient Brain Spike protein was detected by anti-spike antibodies (AAA10931, 0.2 ug/mL) in the brain of the COVID-19 patient confirmed by PCR. (Courtesy of Dr. Nuovo Gerard J., OSU))

IHC (Immunohistochemistry) (Figure 10 IHC Validation of SARS-CoV2 Spike in COVID-19 Patient Lung Strong spike signal was detected by anti-spike antibodies (AAA10931, 0.2 ug/mL) in the lung of the COVID-19 patient confirmed by PCR. (Courtesy of Dr. Nuovo Gerard J., OSU))

IHC (Immunohistchemistry) (Figure 9 IHC Validation of SARS-CoV2 Spike in the Nasopharyngeal Swab Sample of the COVID-19 Patient Strong spike signal was detected by anti-spike antibodies (AAA10931, 0.2 ug/mL) in the nasopharyngeal swab sample of the COVID-19 patient and no spike signal was observed in the sample of the COVID-19 negative patient. COVID-19 cases were confirmed by PCR. (Courtesy of Dr. Nuovo Gerard J., OSU))

IF (Immunofluorescence) (Figure 8 IF Validation of SARS-CoV2 Spike in COVID-19 Patient Skin (Magro et al., 2020) C4d is highlighted green while COVID-19 spike protein detected by anti-spike antibodies (AAA10931, 0.2 ug/mL) shows a red staining pattern; a yellow signal is discernible indicative of co-localization of C4d and viral protein within the microvasculature.)

IF (Immunofluorescence) (Figure 7 IF Validation of SARS-CoV2 Spike in COVID-19 Patient Lung (Magro et al., 2020) SARS-CoV2 spike protein (red, panel C) detected by anti-spike antibodies (AAA10931, 0.2 ug/mL) colocalized with C4d (green in panel d, merged in yellow). Spike protein (red, panel g) was also colocalized with C5b-9 (green in panel f&h, merged in yellow))

IHC (Immunohistchemistry) (Figure 6 IHC/IF Validation in COVID-19 Patient Sample (Nuovo et al., 2020) Detection of SARS-CoV-2 proteins in nasopharyngeal swab cell preparations. B. An intense signal for covid-19 spike protein tested by SARS-CoV-2 spike antibodies (AAA10931) was observed in the glandular cells. F-H. Co-expression of spike detected by spike antibodies (AAA10931, 0.2 ug/mL) and envelope proteins detected by envelope antibodies (, 2 ug/mL) of SARSCoV- 2 (F) documented localization of each protein to glandular cells (G, yellow). No signal was seen in oral swabs of positive cases (H). Both the spike and envelope protein detected by anti-spike antibodies (AAA10931) and anti-envelope antibodies (,) produced a signal in the nasopharyngeal swabs of the three cases and no signal was evident in the nasopharyngeal swabs of the seven controls.)

IHC (Immunohistochemistry) (Figure 5 Immunohistochemistry Validation of SARSCoV-2 (COVID-19) Spike in COVID-19 Patient Lung Immunohistochemical analysis of paraffin-embedded COVID-19 patient lung tissue using anti-SARS-CoV-2 (COVID-19) Spike S2 antibody (AAA10931, 0.5 ug/mL). Tissue was fixed with formaldehyde and blocked with 10% serum for 1 h at RT; antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody overnight at 4°C. A goat anti-rabbit IgG H&L (HRP) at 1/250 was used as secondary. Counter stained with Hematoxylin. Strong spike protein signal wasobserved in macrophages of COVID-19 patient lung.)
