Overview

  • Product name
  • Description
    Rabbit polyclonal to RFP
  • Host species
    Rabbit
  • Specificity
    ab28664 detects RFP tagged proteins. This antibody is specific for the RFP tag. It shows very low reactivity to GFP or GFP tagged proteins. ab28664 non-specifically detects a 45 kDa protein from E. coli extracts. This non-specific cross-reactivity is not present in mammalian samples.

Target

  • Relevance
    Fluorescent proteins have become a useful and ubiquitous tool for making chimeric proteins, where they function as a fluorescent protein tag. Typically they tolerate N- and C-terminal fusion to a broad variety of proteins. They have been expressed in most known cell types and are used as a noninvasive fluorescent marker in living cells and organisms. They enable a wide range of applications where they have functioned as a cell lineage tracer, reporter of gene expression, or as a measure of protein-protein interactions.
  • Alternative names
    • DsRed antibody
    • GFP like chromoprotein antibody
    • red fluorescent protein antibody
    • RFP antibody

Images

  • Western blot of recombinant RFP using ab28664.

  • Immunofluorescent analysis of recombinant Red Fluorescent Protein (RFP)-transfected HeLa cells. Cells were transfected with a pCMV RFP C-Myc plasmid and 48 hours post-transfection cells were fixed with formalin and permeabilized with 0.1% Triton X-100 for 15 minutes at room temperature. Cells were blocked with 3% BSA for 15 minutes at room temperature, and then probed with ab28664 at a dilution of 1/50 for at least 1 hour at room temperature, washed with PBS, and incubated with DyLight® 488-conjugated goat anti-rabbit IgG secondary antibody at a dilution of 1/400 for 30 minutes at room temperature. Nuclei (blue) were stained with Hoechst 33342 dye. Images were taken at 20X magnification.
