Description:
The DRG Herpes Simplex Virus Type 2 IgM Enzyme Immunoassay Kit provides materials for the qualitative and semiquantitative determination of IgM-class antibodies to HSV-2 in serum. This product is for Research Use Only; International customers contact your representative to receive information about the CE marked version.
The DRG Herpes Simplex Virus Type 2 IgM ELISA Kit is a solid phase enzyme-linked immunosorbent assay (ELISA). Patient samples are diluted with Sample Diluent and additionally incubated with IgG-RF-Sorbent, containing hyper-immune anti-human IgG-class antibody to eliminate competitive inhibition from specific IgG and to remove rheumatoid factors. This pretreatment avoids false negative or false positive results. Microtiter wells as a solid phase are coated with native gG2 protein of HSV-2. Diluted patient specimens and ready-for-use controls are pipetted into these wells. During incubation HSV-2-specific antibodies of positive specimens and controls are bound to the immobilized antigens. After a washing step to remove unbound sample and control material horseradish peroxidase conjugated anti-human IgM antibodies are dispensed into the wells. During a second incubation this anti-IgM conjugate binds specifically to IgM antibodies resulting in the formation of enzyme-linked immune complexes. After a second washing step to remove unbound conjugate the immune complexes formed (in case of positive results) are detected by incubation with TMB substrate and development of a blue color. The blue color turns into yellow by stopping the enzymatic indicator reaction with sulfuric acid. The intensity of this color is directly proportional to the amount of HSV-2-specific IgM antibody in the patient specimen. Absorbance at 450 nm is read using an ELISA microtiter plate reader.
