Herpes simplex virus (HSV) is a double stranded DNA, enveloped virus, 110nm to 120nm in diameter. The icosahedral viral capsid is assembled in the host cell nucleus followed by the virus acquiring its envelope by budding through the nuclear membrane at sites modified by the addition of viral protein. The HSV genome encodes over 50 polypeptides, including 9 glycoproteins (gB to gJ), at least 6 capsid proteins, viral protein kinase and DNA polymerase. There are two serotypes, HSV type 1 and HSV type 2 that can be differentiated on the basis of antigenicity of glycoprotein gG. The serotypes have approximately 40% homology leading to antigenic cross reactivity.
Source
HSV, strain MacIntyre, from BSC-1
Applications
Suitable for use in for both IgG and IgM detection in assays which include EIA with polystyrene and latex solid phases. Other applications not tested.
Recommended Dilution
Optimal dilutions to be determined by the researcher.
Inactivation
HSV antigen is inactivated using gamma radiation. This procedure is effective primarily by damaging viral genetic material.
Storage and Stability
Aliquot to avoid repeated freezing and thawing and store at -70°C. Aliquots are stable for 6 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Purity
HSV type 1 grade 2 antigen is collected from both the cell and supernatant phases of tissue culture. Harvest of antigen is carried out by disrupting optimally infected monolayers into the tissue culture medium. Cellular debris is removed by centrifugation.
Form
Supplied as a liquid in tissue culture medium.
