gp41 antibody | AbD08066
A microtiter plate was coated overnight with target antigen HIV gp41-derived chimeric construct, NCCG-gp41, and various negative control antigens at a concentration of 5 μg/ml. After washing and blocking with PBST+5% milk powder, detection was performed using Human Anti-gp41 Antibody (clone AbD08066) at a concentration of 2 μg/ml and Goat Anti-Human IgG F(ab')2:Alk. Phos. Antibody (0500-0100) in HISPEC Assay Diluent (BUF049A) followed by AttoPhos AP Fluorescent Substrate.
Human Anti-gp41 Antibody, Clone AbD08066 specifically recognizes an epitope derived from the ectodomain of the Human Immunodeficiency Virus (HIV) type 1 envelope glycoprotein 41 (gp41).
This antibody was selected from the Human Combinatorial Antibody Library (HuCAL®) by panning on an HIV gp41-derived chimeric construct, NCCG-gp41, as described in Louis et al. 2001.
The fusion of HIV-1 with the membrane of the host cell is the first step in the process of viral infection and replication and involves conformational changes in the gp120 and gp41 viral envelope proteins. It is now known that the HIV 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 panel of B and C type HIV-1 viruses. The crystal structure of the N-HR mimetic 5-Helix with this antibody has been reported (Gustchina et al. 2010, Protein Data Bank ID 3MA9).
