# Understanding the V5 Tag Nucleotide Sequence and Its Research Applications
In the field of molecular biology and protein research, the selection of an appropriate epitope tag is a fundamental decision for the successful expression and detection of fusion proteins. Over the years, my experience in laboratory research has frequently led me to the v5 tag nucleotide sequence. Whether for localized protein analysis or verifying expre Search by Sequence performs a nucleotide-nucleotide or protein-translated nucleotide BLAST search against Addgene’s plasmid … ssion levels in a construct, the V5 system remains a gold standard for specificity.
The V5 epitope is derived from a 14-amino-acid peptide sequence found within the P and V proteins of the Simian Virus 5 (SV5). The specific v5 tag amino acid sequence is universally recognized as: GKPIPNPLLGLDST.
When researchers discuss the v5 tag dna sequence, they are typically referring to the optimized codons used to translate this peptide. A common mammalian expression optimization for this sequence is: `GGT AAG CCT ATC CCT AAC CCT CTC CTC GGT CTC GAT TCT ACG`. Understanding the v5 epitope tag The V5 Tag Sequence: Origin, Function, and Applications sequence at the nucleotide level is crucial for ensuring that your construct remains in-frame during fusion, particularly when using common vectors like the pcDNA3.1/V5-His series.
Technical Specifications and Considerations
When I design experiments using this label, I keep several key parameters in mind:
* V5 tag molecular weight: The peptide itself has a molecular weight of approximately 1.5 kDa (1524.8 Da). When calculating the total weight of a fusion protein, this negligible a V5 Tag Sequence Guide: [The Precision Molecular Tool] ddition is ideal as it minimizes the risk of inter For these applications, the detection, localization, and quantification of heterologous fusion proteins assembled from interchangeable … fering with the target protein's tertiary structure or biological functio Jul 20, 2025 · Synthetic biology has fundamentally advanced cell engineering and helped to develop effective therapeutics such as … n.
* V5 tag size kDa: While the tag is ~1.5 kDa, it is often expressed as part of a larger fusion construct that may include 6xHis or other purification handles, which should be accounted for when analyzing output on Western blots.
Search by Sequence performs a nucleotide-nucleotide or protein-translated nucleotide BLAST search against Addgene’s plasmid …
* Detection: The v5 epitope tag antibody landscape is robust. My preferred approach involves using the well-documented SV5-Pk1 clone. These antibodies offer high affinity for the tag, allowing for clean detection in both immunoprecipitation and immunofluorescence assays.
Research Insights and Practical Application
The versatility of the v5 epitope tag stems from its stability across various pH levels and its proven efficacy in cell engineering. In my personal experience, the most important aspect of working with this system is verifying the sequence of v5 tag integration. Errors in nucleotide sequence design—often involving frame-shift mutations during cloning—are the most common reasons for failed expression.
When conducting homology-directed repair or using plasmid vectors from resources like Addgene, always perform a blast search against the v5 tag dna sequence to ensure your construct aligns perfectly with your open reading frame. Using a reliable v5 epitope tag allows for the Epitope tags Explore widely used epitope tags, such as c-Myc and HA, including their recommended applications and key … rapid identification of tagged molecules within complex cellular environments, making it an indispensable tool for characterizing protein interactions and subcellular localization.
Conclusion
Whether you are scaling up protein production or delving into synthetic biology, the V5 tag provides a high level of reliability. By focusing on the specific v5 tag dna sequence and utilizing high-quality v5 epitope tag antibody reagents, researchers can achieve consistent, reproducible results. Always remember that the purity of your synthetic constructs is paramount, and ensuring the correct v5 tag amino acid sequence is present in your finalized vector is the first step toward successful experimental validation.
