Humoral immune response to the E2 protein of hepatitis G virus is associated with long‐term recovery from infection and reveals a high frequency of hepatitis G virus exposure among healthy blood donors
M Tacke, S Schmolke, V Schlueter, S Sauleda, J I Esteban, E Tanaka, K Kiyosawa, H J Alter, U Schmitt, G Hess, B Ofenloch‐Haehnle, A M Engel – 30 December 2003 – The second envelope protein (E2) of the hepatitis G virus (HGV) was expressed in Chinese hamster ovary (CHO) cells and showed a molecular weight of approximately 60 to 70 kd, with 15 to 25 kd of the size contributed by N‐linked glycosylation. An enzyme‐linked immunosorbent assay (ELISA) using HGV‐E2 was developed to test for antibodies to this protein (anti‐E2) in human sera.
