Product Specifications: Item# 1039: Recombinant HIV-1 YU2 (M Tropic)Envelope Glycoprotein gp41( E.coli) Concentration: See vial Mass/vial: 0.1mg Diluent: 10 mM Tris, pH 8.0, SDS (99% Stabilizer: None Preservative: None Storage: -75°C Physical State: Frozen Liquid Stability: At least 6 months at -75°C. Application: In-Vitro Diagnostics, Cell Activation, CD4 Binding Description: Truncated Recombinant HIV-1 YU2 M-Tropic envelope protein gp41 produced as a fusion protein in the E.coli Expression System. Truncated gp41 protein mol.wt: 25kD. Purification: This protein is purified by affinity chromatography and by preparative electrophoresis to >99% purity as determined by SDS-PAGE, reduced. Specificity: This protein binds to murine anti-gp41 YU2 mAbs and HIV-1 converted human serum polyclonal antibodies in ELISA and Western Elisa. Biological Activity: T-cell activation assays pending 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 100ng of immobilized protein under standard ELISA conditions. Protein concentration for lateral flow rapid diagnostics range from 0.1 – 0.5mg/ml.
