Shelf Life: 12 months
Molecular Weight: 46 kDa
Purity: > 95 % (SDS-PAGE)
Form: liquid (Supplied in 10 mM PBS pH 7.6 and 10 mM NaCl)
Applications:
Antigen in ELISA and Western blots, excellent antigen for detection of HHV-4 (EBV) with minimal specificity problems.
Description:
This protein does contain a GST-tag. The mosaic protein contains fragments of HHV-4 EBNA1 nuclear protein, amino acids: 1-90 and 408-498. The protein is purified by proprietary chromatographic technique.
Background: The Epstein-Barr virus (EBV), a gamma herpesvirus, persists in B lymphocytes for the life of the host. EBNA1 (Epstein-Barr virus nuclear antigen 1) is expressed in every form of EBV-related malignancy, including posttransplant lymphomas. Tumors such as nasopharyngeal cell carcinoma, Hodgkin's lymphoma, and Burkitt's lymphoma (BL) that fail to express some or all of the dominant CD8+ T-cell latent antigens still express EBNA1. A significant proportion of memory CD4+ T-cells that recognize lymphoblastoid cell lines (LCLs) are directed against the EBNA1 protein. The EBNA1 protein contains a glycine-alanine repeat that prevents proper processing and presentation through the major histocompatibility complex class I (MHC I) pathway.
Specificity: Immunoreactive with all sera of EBV infected individuals.
