In the realm of molecular biology research, 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 researchers 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 tag is a small, immunoreactive peptide tag—consisting of only 11 amino acids—which makes it ideal for tagging proteins without significantly altering their native structure or function.

From my experience, the primary utility of these peptides lies in their a c-Myc Peptide Tag (Previously Covance catalog# PEP-150P) bility to simplify protein purification and detection. A c-Myc peptide may be used to elute c-Myc-tagged proteins from affinity colu c-Myc Peptide is a useful for displacement of c-Myc-tagged fusion proteins bound to anti-c-Myc antibodies in immunoassays. The successful inhibition of mns. By competing with the tagged fusion protein for binding sites on the anti-c-Myc antibody, the synthetic peptide 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 c-Myc Tag peptides are substitutes for c-Myc fusion proteins. It is used to competitively bind anti-c-Myc antibodies in immunoassay assay. -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 MYC-Targeting Inhibitors Generated from a Stereodiversified 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.
