In the field of biochemical research, specific protein fragments serve as essent PLP (139-151) | Neuronal Metabolism ial tools for understanding complex biological pathways. One such tool is the PLP139 151 peptide, a synthetic fragment derived from the myelin proteolipid protein (PLP). As someone who closely follows advancements in laboratory reagents, I have found that the study of these sequences provides significant insights into how the c We previously generated a panel of T helper cell 1 (Th1) clones specific for an encephalitogenicpeptideof myelin proteolipid protein (PLP)peptide139–151( Read more entral nervous system (CNS) interacts with various immune components.
What is the PLP139 151 Peptide?
The PLP (139-151) peptide represents a specific amino acid sequence—HSLGKWLGHPDKF—found within the native myelin proteolipi ThePLP [139-151] peptidefrom the myelin proteolipid protein (PLP) has been found to be highly immunogenic in inducing experimental allergic encephalomyelitis Read more d protein. Myelin is a critical component of the CNS, and the amino acid residue 139 to 151 of myelin proteolipid protein (PLP) has been identified as a major encephalitogenic epitope.
In experimental settings, researchers utilize this synthetic myelin proteolipid protein (PLP) fragment to observe interactions at the molecular level. It is frequently employed in immunological studies to evaluate how specific sequences can influence T cell responses. Because PLP139-151 is one of the major encephalitogenic epitopes of PLP, it serves as a standard reference point for those studying cellular behavior in controlled environments.
Experimental Utility and Variants
The versatility of this reagent is highlighted by the various modifications available to researchers. For instance, the [Ser140]-PLP (139-151) variant and the [Gln144]-PLP (139-151) analog are often used to compare how slight structural changes affect binding PLP (139-151) peptide affinity and cellular activation. These modified versions allow for a deeper understanding of the PLP(139-151) epitope’s behavior compared to its native state.
Another area of interest is the development of cyclic PLP139-151 structures. By cyclizing the peptide, researchers have observed differences in immunological activity compared to linear versions. Whether you are looking at PLP (139-151) or related fragments like PLP (178-191), the primary goal remains the same: to generate data that clarifies the function of these proteins in vitro. For example, the Myelin PLP (139-151) active peptide is often used in culture media; it is used in vitro to generate encephalitogenic T cells or to evaluate specific proliferative responses.
Practical Considerations for Researchers

Many suppliers offer this 151 amino acid-derived sequence in various quantities, such as 1mg or 15mg vials. Based on my experience with laboratory reagents, it is vital to ensure that the product is handled according to the manufacturer's storage guidelines to maintain its integrity.
It is also important to distinguish between various research needs. While some may confuse this with other peptides like BPC-157 or other peptide 151 variations, it is crucial to maintain focus on the specific epitope being stu Myelin PLP (139-151) active peptide died. The scientific literature consistently emphasizes that PLP(139-151) is a specialized tool for research use only. It is not intended for any form of human use, and reputable supp 151 peptide 151 - peptides669.info liers will explicitly state that they do not sell to patients.
Conclusion
The PLP (139-151) peptide remains a cornerstone in the study of myelin-related immunology. From the basic PLP139 sequence to more complex SER140]-PLP(139-151) modifications, these tools provide a window into the mechanisms of the CNS. By using these well-characterized sequences, the scientific community continues to refine its understanding of protein interactions, ensuring that every of myelin proteolipid protein (PLP), peptide 139-151 experiment contributes to a larger body of verifiable, peer-reviewed knowledge.
