Cat#:RP-3776H;Product Name:Recombinant Human HIV-1 Envelope Protein;Synonym:HIV;Description:HIV-1 envelope is an E.coli-derived recombinant protein that composes all of the reported immunogenic determinants found in gp41 and a small portion of gp120. The gene encoding this fusion protein was synthesized using codons optimized for E.coli expression and doesn’t represent a linear HIV-1 envelope sequence. HIV-1 is a non-glycosylated, 233 amino acid polypeptide chain, having a molecular mass of 27275.88 dalton and pI=9.68. HIV-1 envelope protein spans the C-Terminus of gp120 and most of gp41. Superior diagnostic reagent for HIV-1 and HIV type-O detection. Detects all HIV-1 and HIV-type O infected individuals responding to envelope proteins.;Source:E.coli;Purity:Greater than 95.0% as determined by HPLC analysis and SDS-PAGE.;Formulation:The HIV-1 contains 0.5X PBS & 6M urea.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Storage:HIV-1 Envelope although stable at 4°C for 1 week, should be stored below -18°C. Please prevent freeze thaw cycles.;
