Red Fluorescent Protein (RFP)
Red Fluorescent Protein (RFP) is a versatile biological marker for monitoring physiological processes, visualizing protein localization, and detecting transgenic expression in vivo. RFP can be excited by the 488 nm or 532 nm laser line and is optimally detected at 588 nm.

Life Technologies offers a series of RFP CellLight® fusion constructs of signal peptides or cell structure proteins with tagRFP for accurate and specific targeting to subcellular structures, including the cytoskeleton, mitochondria, and secretory compartments.

To complement these tools, we also offer anti-RFP antibodies and antibody conjugates for a wide variety of applications, including imaging, western blotting, and flow cytometry. All of our anti-RFP antibodies are suited for detection of native RFP, RFP variants, and CellLight® fusion proteins.

RFP products

CellLight® reagents

CellLight® reagents are ready-to-use fluorescent protein constructs targeted to specific subcellular structures. These reagents provide a simple and effective method for introducing targeted intracellular labels within living cells. Simply add the reagent to your cells, incubate overnight, and you’re ready to image your cells.

 

Anti-GFP antibodies

Anti-GFP antibodies provide a convenient method for visualizing GFP, especially when amplification of the fluorescent protein of interest is necessary to overcome a dim or degraded signal. Our anti-GFP antibodies are easily incorporated into standard immunostaining protocols for cell and tissue analysis.

rfp-imaging

Specificity of anti-RFP rabbit polyclonal antibody in immunocytochemistry (ICC). Following fixation and permeabilization, HeLa cells were stained with Alexa Fluor® 350 phalloidin and anti-RFP rabbit polyclonal antibody, the latter subsequently visualized with Alexa Fluor® 647 Goat Anti-Rabbit IgG antibody, red fluorescence and imaged. No cross-reactivity is observed of the anti-RFP antibody with GFP (green-fluorescence, perinuclear region).

BacMam technology

  • Efficient transduction of cell lines, including primary cells and stem cells
  • Safe transduction and lack of observable cytopathic effects
  • Easy modulation of gene expression
  • Expression of multi-component complexes at the right stoichiometry

The BacMam technology is based on double-stranded DNA insect viruses (baculovirus) as vehicles to efficiently deliver and express genes in mammalian cells, including those encoding fluorescent proteins. such as Red Fluorescent Protein. Baculoviruses are well-tolerated and nonreplicating in mammalian cells, so they have an excellent safety profile for routine applications.

Antifade reagents

Antifade reagentsAntifade reagents suppress photobleaching and preserve the signals of your fluorescently labeled target molecules. They offer excellent compatibility with a multitude of dyes across the spectrum, making them especially valuable tools for multicolor applications. For added convenience, some formulations include the nuclear counterstain DAPI, eliminating the need for a separate counterstaining step.
