S-tag protein The S-peptide tag, a term frequently encountered in molecular biology research, refers to a specific oligopeptide derived from pancreatic ribonuclease A (RNase A). This peptide tag is a crucial component in various biotechnological applications, primarily for the detection and purification of proteins. Its utility stems from its unique biochemical properties and the well-characterized interaction it forms with its corresponding binding partner, S-protein.S-tag Antibody, pAb, Rabbit

The S-tag itself is a relatively short sequence, typically comprising 15 amino acids. A common sequence cited is KETAAAKFERQHMDSS-peptide epitope tagging for protein purification .... This specific sequence is generated when pancreatic RNase A is digested with subtilisin, leading to the cleavage of a single peptide bond.S-peptide Epitope Tag Antibody from Thermo Fisher ... The resulting fragment, the S-peptide epitope tag, retains the ability to bind strongly and specifically to S-protein, which is the larger portion of the cleaved RNase A. This specific interaction forms the basis of the S-Tag system, a widely recognized protein tagging and detection system.S-tag is the name of an oligopeptide derived from pancreatic ribonuclease A(RNase A).

The application of epitope tags in modern research is extensive, with the S-peptide epitope tagging method being a prime example. Epitope tags are widely used in cell biology and biochemistry research because they allow researchers to introduce a short, identifiable sequence onto a protein of interest. This tag then acts as a molecular handle, facilitating a range of downstream analyses.The S-peptide Epitope Tag Antibody from Thermo Fisher Scientificis a Mouse Monoclonal antibody. The S-peptide Epitope Tag Antibody has been validated for the ... The S-peptide tag is particularly advantageous due to its small size, which minimizes the potential for interfering with the native function or folding of the target protein. Furthermore, the S-tag is often engineered onto either the N- or C-terminus of a protein of interest, offering flexibility in experimental design.

One of the primary applications of the S-peptide tag is in protein purification. By fusing the S-tag to a recombinant protein, researchers can efficiently isolate the target protein from complex cellular mixtures. This is achieved by immobilizing S-protein onto a chromatography resin. When the cell lysate containing the tagged protein is passed over this resin, the S-tag binds specifically to the immobilized S-protein, allowing the tagged protein to be captured.S-tag is the name of an oligopeptide derived from pancreatic ribonuclease A(RNase A). If RNase A is digested with subtilisin, a single peptide bond is cleaved, ... Unbound proteins are washed away, and the tagged protein can then be eluted by disrupting the S-tag and S-protein interaction, often using specific buffer conditions or competitive peptides. This method is highly effective for achieving high purity levels. The S Tag purification kit is a common tool employed for this purpose.

Beyond purification, the S-peptide tag is instrumental in protein detection and analysis. The strong and specific binding of the S-tag to S-protein allows for sensitive detection using various immunological methodsS Tag Peptide (25mg). This includes the use of S-Tag antibodies, which are specifically designed to recognize and bind to the S-tag sequence. These S-Tag antibodies can be used in techniques such as Western blotting, ELISA, and immunofluorescence microscopy to confirm the presence and localization of the tagged protein.

For instance, a Synthetic peptide corresponding to S tag conjugated to keyhole limpet haemocyanin is often used in the production of these antibodies.

The S-peptide tag is also known for its ability to enhance protein solubility. Due to its abundance of charged and polar residues, the tag can improve the solubility of recombinant proteins, which may otherwise aggregate or precipitate within the cell. This is a significant advantage, especially when working with proteins that are prone to poor solubilityS•Tag : A Multipurpose Fusion Peptide for Recombinant ....

The interaction between the S-tag and S-protein is a classic example of how intrinsically unstructured peptides can adopt a defined structure upon binding to their specific substrate. This characteristic makes the S-tag a valuable tool, as it minimizes the likelihood of interference from naturally occurring molecules in the cellular environment. The Tag peptide and the S-protein interaction is highly specific, ensuring that only the intended tagged protein is recognized.The S-peptide Epitope Tag Antibody from Thermo Fisher Scientificis a Mouse Monoclonal antibody.
