Tests of antiviral substances

This Bioreader® supports testing and development of antiviral  substances.

Example#1: The automatic analyses of Plaque reductions assay.

This assay applies diluted doses of a -possibly- antiviral drug into multiwell plates. The Bioreader automatically observes its capability to suppress the formation of plaques (-holes-) in the bacterial lawn.

The ‘Plaque reductions neutralization test’ (PRNT) is a variation of this test. It is an attempt to find an antibody that neutralizes a specific virus. This is a very valuable tool in antiviral vaccine research.

Examplel#2: The automatic evaluation of the Yield reduction assay

In several steps of operation cells are infected in presence of variable doses of a possibly antiviral drug substance.

Thereafter the virus titer is determined in the liquid by use of the plaque or TCID50 assay with of the Bioreader®.

The titer is calculated as the quotient of the positive cells/all cells, taking in account the virus dilution factor and the volume of the inoculum.

"The focus forming assay (FFA) is a variation of the plaque assay, but instead of relying on cell lysis in order to detect plaque formation, the FFA employs immunostaining techniques using fluorescently labeled antibodies specific for a viral antigen to detect infected host cells and infectious virus particles before an actual plaque is formed."

"The enzyme-linked immune absorbent spot (ELISpot) is a type of assay that focuses on quantitatively measuring the frequency of cytokine secretion for a single cell."

[https://en.wikipedia.org/wiki/ELISpot]

Why Elispot?

The cytokine Elispot assay is designed to enumerate cytokine secreting cells in single cell suspensions of lymphoid tissue, CNS tissue, bone marrow or preparations of peripheral blood mononuclear cells (PBMC).

The assay has the advantage of detecting only activated/memory T cells and the cytokine release can be detected at the single cell level, allowing direct determination of T cell frequencies.

The ELISPOT assay is an effective tool to enumerate antigen-specific T cells in the circulation of immunized humans and animals at much lower frequencies than possible with other currently available methods.

The ELISPOT assay has proven to be a sensitive and unique system to follow disease progression in human individuals or animals. Several studies have indicated that alterations in the frequency of cytokine pc in different compartments of the body adequately reflect changes in immune function.

The ELISPOT assay may be used to determine effects of drugs, chemicals or other compounds on cytokine secretion in vitro, thereby providing data on their putative modulatory effects on immune function in vivo

The ELISPOT assay is currently being used increasingly for the quantitative assessment of peptide reactive T lymphocytes from PBMC in infectious disease (3, 9) or in the course of vaccination trials aimed at the induction of tumor-specific T cells in patients with cancer.

Elispot may be used for Diagnosis of genetic defects,Allergic diseases,Autoimmune diseases,Transplantation,Cancer research,Acute inflammation,Acute infectious diseases and septic shock.

The alveolar epithelium is a major target in toxic exposures of the lung because of its structural delicacy and proximity to inhaled toxicants. Type II epithelial cells are important in maintaining the integrity of alveolar epithelium and normal lung function.
