    Notes

    The Red Fluorescent Protein (DsRed) antibody ABIN967350 reveals a protein of the expected molecular weight (31kDa) in lysates of cells infected with DsRed or with DsRed and EGFP expressing virus. A slightly lower MW band is visible in the lysates of EGFP (expected MW 28kDa) expressing cells. This might reflect some cross-reactivity of the DsRed antibody with the structurally similar EGFP. However, the overall selectivity of ABIN967350 towards DsRed is very good.

    Sujet
    DsRed is naturally occurring fluorescent protein from a coral of the genus Discosoma. DsRed, like green fluorescent protein (GFP) can be introduced into either cultured cells or in transgenic animals to study the localization of a specific protein. It can also be used in fusion constructs with a protein of interest to examine protein-protein interactions or as a general marker. The crystal structure of DsRed has been solved and shown that DsRed monomers exhibit similar topology to GFP, but have additional chemical modifications which account for differences in the spectra, when compared to GFP. DsRed has a longer emission/absorption wavelength than GFP. DsRed migrates at 31 kDa in SDS/PAGE. The antibody recognizes three forms of DsRed, 1, 2 and pTimer. A recombinant protein representing DsRed1 was used as the immunogen.
