概述

  • 产品名称
  • 描述
    兔多克隆抗体to RFP
  • 特异性
    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.

靶标

  • 相关性
    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.

  • Predicted band size : 26 kDa

    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.

Thank you for contacting us.

To our knowledge, the antibody ab62341 has not been tested for reactivity with mCherry. I suggest trying ab28664, if you only plan to use it for western blotting, because the immunogen sequence, VNGHEFEIEGEGEGR, ...

Thank you for your inquiry.


The antibody was raised against amino acids 22-36 of the RFP protein, which is made up of a single 231 amino acid polypeptide chain. The lab said that theprotein doesn't exist in any other form,that it is alw...

Thank you very much for your interest in Abcam anti-RFP antibodies. ab28664 was recommended to your colleague because the homology between the immunogen and the mCherry is 100%. ab62341 was raised using the whole RFP, which has 82% homology with mCher...
