In the realm of molecular biology resea The Myc tag is a small, immunoreactive peptide tag (11 amino acids) that is ideal for co-immunoprecipitation studies and Western blots. It binds to the cMyc rch, the c-Myc peptide has established itself as an indispensable tool for protein characterization and laboratory analysis. As a user who frequently engages with various biochemical reagents for experimental workflows, I have found that understanding the specific mechanics of this synthetic peptide is essential for successful immunoassay outcomes.
Defining the c-Myc Peptide and Its Origins
The c-Myc peptide is a synthetic sequence that corresponds to the amino acids 410-419 of the C-terminal of the human c-Myc protein. Often referred to as the EQKLISEEDL sequence, this specific epitope is the target recognized by various anti-c-Myc antibodies. Because the Myc-tag is a peptide tag derived from the c-Myc protein, it serves as a highly reliable marker in recombinant DNA technology.
When rese Sep 13, 2016 — We are going to clone a protein in a pCMV-Myc plasmid. Looking for fluorochrome-conjugated antibodies to track the efficiency of transfection, I found both archers discuss the Myc-tag, they are referring to a polypeptide protein tag derived from the c-Myc gene product that can be fused to proteins of interest. This Myc ta Pierce™ c-Myc Peptide 5 mg | Buy Online g is a small, immunoreactive peptide tag—consisting of only 11 amino acids—which makes it ideal for tagging proteins without signi Myc-tag: An epitope tag for protein characterization, ficantly altering their native structure or function.
Practical Applications in the Laboratory
From my experience, the primary utility of thes The Myc tag is a small, immunoreactive peptide tag (11 amino acids) that is ideal for co-immunoprecipitation studies and Western blots. It binds to the cMyc e peptides lies in their ability to simplify protein purification and detection. A c-Myc peptide may be used to elute c-Myc-tagged proteins from affinity columns. By competing with the tagged fusion protein for binding sites on the anti-c-Myc antibody, the synthetic pepti c-Myc Peptide TFA | Growth Regulated Agent de allows for the gentle, non-denaturing release of the target protein. This is why c-Myc Tag peptides are substitutes for c-Myc fusion proteins in competitive binding assays.
Furthermore, this peptide usually contains the epitope recognized by the antibody, which is why it is often used as a protein modification to simplify labeling. Whether you are performing immunoprecipitation or Western blots, the precision offered by this tag is unparalleled. While a c-Myc Antibody detects endogenous levels of total c-Myc protein, the tag allows for the specific tracking of exogenous, recombinant proteins.
Scientific Context: The Role of c-Myc
It is important to distinguish between the tag and the protein itself. c-Myc is a proto-oncogene that encodes a transcription factor crucial for cellular processes. As a transcription factor that binds DNA in a non-specific manner, it acts as a central regulator of cell growth and proliferation. Because c-Myc is a key regulator of cell growth, it remains a major subject of interest in structural biology.
Advanced research has even led to the development of synthetic molecules like IDP-121, a stapled peptide specifically designed to target c-MYC protein, demonstrating how far our manipulation of these sequences has evolved.
Why Researchers Choose the c-Myc System
1. Versatility: As one of the most common antibody tags, the c-Myc system is supported by a vast ecosystem of commercially available reagents.
2. Specificity: The c-Myc peptide EQKLISEEDL provides a clean binding profile, reducing background interference in complex lysates.
3. Stability: Many researchers prefer the c-Myc Peptide (TFA) form, which is a lyophilized powder, for its long-term stability and ease of reconstitution in laboratory buffers.
Whether you are working with c-Myc (Myc) fusion constructs or investigating the binding kinetics of transcription factors, the c-Myc peptide remains a foundational element of modern molecular research. By maintaining a clean experimental design and utilizing well-characterized peptide tags, one can achieve highly reproducible results in pr Pierce™ c-Myc Peptide. The c-Myc peptide may be used to elute c-Myc-tagged proteins from Thermo Scientific Anti-c-Myc Agarose, when the bound protein is otein purification and analytic detection.
