MDCK cells (ATCC) were used for the preparation of virus stocks and for virus titration by plaque assay. Cell culture Calu-3 cells were kindly provided by Dr. Suchitra Kamle, Brown University. Cells ...

An immunofluorescence assay reveals their presence only within the plaques and the adjacent area. [2–4] A significant reduction in plaque size is observed when antiserum is mixed with a standard ...

SALT LAKE CITY, Jan. 3, 2025 /PRNewswire/ -- ARUP Laboratories today launched a new assay for the detection and subtyping of influenza A (H5) virus. This test will aid in the evaluation of ...

SALT LAKE CITY, Jan. 3, 2025 /PRNewswire/ -- ARUP Laboratories today launched a new assay for the detection and subtyping of influenza A (H5) virus.

To identify the ratio between the virus library and human serum that reduced virus titers ≥1000-fold compared to the untreated virus library in the absence of human serum, we mixed library aliquots ...

The 1918–1919 Spanish influenza pandemic was estimated to have infected one-third of the world's population and accounted for 50–100 million deaths. 1 In early 2009 attention was drawn to the ...

Infectious virus titre in swabs was measured by plaque assay on MDCK cells (b, c). c Bird ID number for directly inoculated ANP32AN129I-D130N birds above the detection limit is indicated.

Nevertheless, the traditional viral plaque assays require an incubation period of 2~14 days, followed by sample staining using chemicals and human visual inspection to count the number of viral ...

The antiviral activity of purified FRIL protein and lablab bean powder was also examined against the Influenza H1N1, H3N2, and Coronavirus HCoV-OC43 via plaque reduction assays.

This observation is particularly interesting in view of the mounting evidence in support of a significant role for influenza in triggering plaque rupture in murine models 23 and human clinical studies ...
