Viral Load Determination

Price on request

Determines infectious virus particles in a sample. Virus is sequentially diluted and dilutions are plated on susceptible cells. Cultures are overlaid with nutrient agarose and plaques or pocks formed by cytopathic viruses can be quantitated.

Radial Immunodiffusion Assay

Price on request

The SRID Assay is used to quantitate the amount of antigen in a sample. Antigen concentration is determined by the degree of antigen/antibody precipitate around a well into which detergent solubilized virus is placed. A standardized antigen preparation and a specific polyclonal antibody are required.

We offer custom construction of recombinant bacteriophage containing your gene of interest.

The similarity between animal viruses and bacteriophage in their structure, physicochemical properties and infection dynamics is striking. Bacteriophage are viruses infecting bacteria and are known to be specific for E. coli, staphylococcus and all bacterial genus. We apply many techniques we have developed in understanding animal viruses to bacteriophage with great results.

  • VIRAPUR has engineered bacteriophage containing control viral genes as lysis controls for viral PCR assays.
  • We can engineer a phage expressing or containing your gene of interest.
  • We can purify phage to pharmaceutical grade to high concentrations and low endotoxin.

The IC50 (50% Inhibitory Concentration) of an antiviral drug can be determined using tissue culture. A sample of known virus concentration is incubated with susceptible cells in the presence of increasing concentrations of an antiviral drug. This assay determines the concentration at which the drug will inhibit virus replication. This can also be done using antibodies in the place of drugs, in which case it is called a Microneutralization Assay.

Quantitates infectious virus particles in a sample. Virus is sequentially diluted and dilutions are plated in replicate wells of susceptible cells. The TCID50 (50% Tissue Culture Infectious Dose) is that dilution of virus which will produce pathological change in fifty percent of cell cultures inoculated at a particular dilution. TCID50 values are normally very close to the Plaque Assay values for most cytopathic viruses.

Microneutralization Assay

Price on request

An excellent test to determine if an antibody may have therapeutic effects. This assay measures the ability of an antiserum to inhibit cytopathogenic effect of about 100 virus infectious units. The antibody/virus mixture is plated on susceptible cells and inhibition is tracked.

Detects the presence of certain viruses that agglutinate red blood cells. This assay can be used to quantitate or type many virus strains. For example, influenza virus possesses the capacity to agglutinate red blood cells of specific animal species. It does this by cross linking sialic acid residues on the surface of red blood cells. In some labs, the hemagglutination assay is preferred for detecting influenza virus growth. The hemagglutination titer of an influenza virus sample can be determined when dilutions of virus are mixed with human or turkey red blood cells. The presence of virus will hold the red cells in a diffuse matrix and prevent them from settling out to the bottom of the well.

Hemagglutination Inhibition (HI/HAI) Assay
This test is based on the inhibition of viral agglutination by a specific antibody and can be used for virus identification or for assay of antibodies. This assay is still used as a standard for measuring the efficacy of influenza vaccines and potency of neutralizing antibodies.
