ToRCH Antigens

Product Name  EL Catalogue Number Product Description
Toxoplasma gondii, Grade IgG EL-18-07

Description: Native Toxoplasma gondii antigens are obtained by extracting and subsequently centrifuging Toxoplasma tachyzoites from infected cell cultures.

Strain: RH

Buffer: 1% Triton x-100, Phosphate Buffered Saline pH 7.4

Toxoplasma gondii, Grade IgM EL-18-08

Description: Toxoplasma Antigen, IgM Grade is produced by subjecting Toxoplasma tachyzoites to membrane fractionation, which allows for surface antigen isolation, specifically Toxoplasma p30.

Strain: RH

Buffer: 2% N-octyt–D-glucopyranoside (OGP) in Phosphate Buffered Saline pH 7.4

Rubella BR2S EL-05-15

Description: The predominant form of the antigen is whole virions suspended in NTE with sucrose. The preparation is free of detergent. Residual non-viral protein may come from host tissue and culture medium.

Strain: HPV-77

Buffer: NTE buffer (Sodium chloride, TRIS and EDTA)

Cytomegalovirus, Grade 2 EL-01-02

Description: This preparation contains CMV antigens from all parts of the virus cycle of replication including early and late antigens, nuclear antigen, cytoplasmic antigen, structural and non-structural proteins. The antigen is in GBS without detergent or preservative. This preparation contains residual host cellular material.

Strain: AD-169

Buffer: Glycine buffered saline (GBS) pH 9.5

Herpes Simplex 1, Grade 2 EL-02-02

Description: Herpes Simplex 1 Grade 2 antigen contains a high concentration of virus particles and components in tissue culture medium containing a low concentration of bovine serum. The preparation contains no preservative or detergent. Some residual host cellular material is present.

Strain: MacIntyre

Buffer: Tissue culture medium

Varicella-Zoster, Grade 2 EL-03-02

Description: The resulting antigen preparation contains a high concentration of virus and viral components as well as some cellular material suspended in EMEM with some serum proteins.

Strain: VZ-10

Buffer: EMEM

EBV Purified Antigen ‘VCA’ (glycoprotein B, gB, BALF4) EL-16-06

Description: This preparation contains more than 90% virus specific protein. The predominant form of the antigen is purified protein suspended in 20mM Tris-HCl with 3M MgCl,; pH 7.4. The preparation is free of detergent. Any residual non-viral protein comes from host tissue and culture medium. The protein concentration is nominally 0.030 mg/ml.

Strain: P3H3 cells infected with EBV

Buffer: 20mM Tris-HCl with 3M MgCl2; pH 7.4

EBV Purified Antigen ‘VCA’ (glycoprotein B, gB, BALF4) Concentrate. EL-16-07

Description: This preparation contains more than 90% virus specific protein. The predominant form of the antigen is purified protein suspended in 20mM Tris-HCl with 3M MgCl2; pH 7.4. The preparation is free of detergent. Residual non-viral protein comes from host tissue and culture medium. This preparation is a more concentrated for of EL-16-06 with a protein concentration is nominally 0.10 mg/ml.

Strain: P3H3 cells infected with EBV

Buffer: 20mM Tris-HCl with 3M MgCl2; pH 7.4
