Description: Gene cloned from Macrophage -cell-tropic HIV-1 YU2 strain and the full length recombinant envelope gp120 glycoprotein produced in the Baculovirus Expression System.

Purification: This protein is purified by immuno-affinity chromatography to >95% purity as determined by SDS-PAGE, reduced.

Specificity: This protein binds to murine monoclonal antibodies of defined epitope specificity and HIV-1 converted human serum polyclonal antibodies in ELISA and Western ELISA.

Biological Activity: This protein binds to human T-cell receptor CD4 in ELISA and Western ELISA as determined by CD4/gp120/Anti gp120 mAb-peroxidase capture ELISA. Cell activation assays in progress.

Application and Instructions for use

Recommended concentrations for use are approximate values. A dose dependent response assay should be performed to determine the optimal concentration for use in specific applications. ELISA and Western ELISA require 10-100ng protein depending on the nature and affinity of the detection reagent. Human serum polyclonal antibodies yield titers of 1:1000 or greater at 10-100ng of immobilized protein under standard ELISA conditions. Application: Human diagnostics, CD4 binding, Drug screening, Human T-cell CD4 receptor binding and co-receptor binding studies.
