The Goat Anti-Anti-mTangerine Polyclonal IgG Antibody is a specialized reagent used in various molecular and cellular biology applications. This antibody is designed to specifically recognize and bind to the mTangerine fluorescent protein, a derivative of the popular mFruit series of fluorescent proteins. This makes it a critical tool for researchers using mTangerine-tagged proteins in live-cell imaging, protein localization studies, and other fluorescence-based assays. Below, we explore the key features, applications, and benefits of this antibody in detail, alongside references to authoritative educational and governmental sources.
What is mTangerine?
mTangerine is a red fluorescent protein (RFP) that has been engineered for monomeric stability and bright fluorescence in biological imaging experiments. It belongs to the mFruit series, which includes several variants of red fluorescent proteins derived from the Discosoma coral. These proteins are widely used to tag proteins of interest for visualization in living cells, tissues, and organisms. For a more in-depth look at fluorescent proteins, visit NCBI and NIH.
mTangerine’s fluorescence emission spectrum peaks around 585 nm, making it ideal for imaging applications that require a bright, stable red fluorescent marker. Its rapid maturation time and excellent photostability are other factors that make it highly valuable in various fluorescence microscopy techniques. For a deep dive into the properties and applications of mTangerine and other fluorescent proteins, consult resources like the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC).
Structure of Goat Polyclonal IgG Antibody
Polyclonal antibodies are produced by immunizing animals (in this case, goats) with the mTangerine antigen. These antibodies are generated by multiple clones of B-cells, each recognizing different epitopes (regions) on the mTangerine protein. This multi-epitope binding provides polyclonal antibodies with a heightened sensitivity, making them particularly effective in detecting low-abundance targets or in assays where multiple epitopes are accessible.

Applications of Goat Anti-Anti-mTangerine Polyclonal IgG Antibody
- Immunofluorescence and Fluorescence Microscopy:
- This antibody is often used in immunofluorescence (IF) assays to detect mTangerine-tagged proteins within cells. By coupling the antibody with a secondary fluorescent label, researchers can visualize the location and expression levels of the target protein. The high specificity of the antibody ensures that only mTangerine is detected, providing clear and accurate imaging results.

- Western Blotting:
- In western blotting, this antibody is used to detect mTangerine proteins from cell lysates after separation by gel electrophoresis. The polyclonal nature of the antibody ensures strong binding to multiple epitopes, allowing for the sensitive detection of the mTangerine protein even at low expression levels. For protocol references, visit Harvard University’s western blotting techniques page.
- Flow Cytometry:
- The antibody is highly effective in flow cytometry, where it helps quantify and sort cells expressing mTangerine-tagged proteins. Flow cytometry allows for the analysis of fluorescence intensity in individual cells, making it possible to isolate specific cell populations. For more on flow cytometry protocols, visit NIH’s flow cytometry core facilities and CDC’s flow cytometry guide.
- Immunoprecipitation (IP):
- This antibody can be used in immunoprecipitation experiments to pull down mTangerine-tagged proteins from complex mixtures, such as cell lysates. This enables the isolation and analysis of protein-protein interactions, offering deeper insights into cellular mechanisms. For advanced IP methods, refer to Stanford University’s antibody resource guide.
Advantages of Using Goat Polyclonal IgG Antibodies
- Enhanced Sensitivity: Polyclonal antibodies bind to multiple epitopes on the target protein, increasing the likelihood of detecting mTangerine, especially in assays where protein abundance is low. This makes them a better option in certain applications compared to monoclonal antibodies, which bind to a single epitope. Learn about the benefits of polyclonal antibodies at NCBI’s antibody technology page.
- Broad Epitope Recognition: The broad recognition capability of polyclonal antibodies allows them to recognize proteins that have undergone slight modifications, such as phosphorylation or other post-translational modifications. This flexibility is crucial in many assays where target proteins may exist in different forms. Further explore this at FDA’s antibody information page.
Handling and Storage Conditions
For optimal performance, the Goat Anti-Anti-mTangerine Polyclonal IgG Antibody should be stored under specific conditions to maintain its activity and stability:
- Short-term storage: 4°C
- Long-term storage: -20°C (avoid multiple freeze-thaw cycles)
- Proper handling protocols are essential to maintain antibody performance. For more details on antibody handling and storage, visit the CDC’s laboratory guidelines.
Troubleshooting and Optimization Tips
- Low Signal in Immunofluorescence or Western Blot:
- Ensure sufficient amounts of the antibody are used. If the signal remains low, optimize the antibody dilution or extend the incubation time. See troubleshooting tips from Harvard’s Immunology Research Center.
- Non-Specific Binding:
- Non-specific binding can be minimized by using blocking agents, such as bovine serum albumin (BSA) or non-fat milk. For more on reducing background noise in antibody assays, refer to this FDA guideline on assay development.
