Human anti gp41, Clone AbD08066 specifically recognizes the Human Immunodeficiencey Virus (HIV) envelope glycoprotein 41 (gp41).
The fusion of the HIV-1 with the membrane of the host cell is the first step in the process of viral infection and replication and involves confomational changes in the gp120 and gp41 viral envelope proteins. It is now known that the HIV envelope glycoprotein gp41 contains a highly conserved N-heptad repeat (N-HR) region which is conserved in many HIV-1 strains and as such it is hypothesized that this maybe a target for developing a vaccine (Gustchina et al. 2010).
Clone AbD8066 is a unique antibody that has been shown to be broadly neutralizing across a wide range of primary isolates from HIV-1 subtypes B and C (Gustchina et al. 2010).
A monovalent human recombinant Fab (lambda light chain) selected from the HuCAL® phage display library, expressed in E. coli. The antibody is tagged with a myc-tag (EQKLISEEDL) and a his-tag (HHHHHH) at the C-terminus of the antibody heavy chain. This antibody is supplied as a liquid.
Metal chelate affinity chromatography
Recombinant protein corresponding to a conserved internal trimeric coiled-coil of the N-heptad repeat (N-HR) of HIV-1 gp41.
