In the field of molecular biology and protein research, the cmv pp65 peptide sequence remains a cornerstone for those investigating the structural and functional properties of the human cytomegalovirus. As someone who frequently explores the technical specifications of biological reagents for research purposes, I have found that understanding the nuances of the tegument protein pp65 is essential for any laboratory work involving the cytomegalovirus.
The Architecture of pp65
The pp65 protein, also known as the UL83 tegument protein, is a 65 kDa phosphoprotein that acts as a major structural component of the virus. When analyzing the pp65 sequence, it becomes clear why this specific protein is so frequently utilized in experimental assays. The phosphoprotein 65 (pp65) is a prim CEF20 ary target for cellular immune investigations, and its broad range of epitopes allows for a comprehensive assessment of protein-specific responses.
From my experience, when sourcing materials, the lyophilized mixture of 138 peptides—often referred to as a PepTivator CMV pp65—is the gold standard for full-coverage studies. These 15-mer sequences with 11-amino-acid overlaps are engineered to span the en by SJ Hyun·2017·Cited by 44—Analysis of the fine specificity ofpp65-specific CTL showed that some donors have a highly focused response recognizing only a singlepeptide, whereas others Read more tire protein, ensuring that researchers can map responses across the full length of the CMV phosphoprotein pp65.
Key Epitopes and Their Sequences
Specific segments of the CMV pp65 are highly sought a CMV pp65 peptide fter due to their well-documented binding affinities. Among these, the HLA-A*0201-restricted epitope is perhaps the most famous. The HCMV pp65 (495-503) peptide—with the peptide sequence: H-NLVPMVATV-OH—is a vital reference point for researchers. Having worked with thi CMV phosphoprotein pp65is thought to be a major antigen for CMV-specific cellular immunity. Synonyms, MHC; HLA-A*02:01; CMV pp65. Learn More. Back. For Read more s single peptide (NLVPMVATV), I can confirm that its stability and purity are critical for accurate results in tetramer staining or other PE-Labeled Human HLA-A*02:01&B2M&CMV pp65 analytical methods.
Other notable sequences include:
* CMV pp65(91-100): Often utilized for its HLA-A33-restricted properties.
* CMV pp65 (415-429): Represented by the Thr-Pro-Arg-Val-Thr-Gly-Gly-Gly-Ala-Met (TPRVTGGGAM) sequence.
* CMV pp65 (113-121): Known as the VYALPLKML sequence.
* CMV pp65 (120-129): Identified as MLNIPSINV.
* H-Gln-Tyr-Asp-Pro-Val-Ala-Ala-Leu-Phe-OH: A specific 9-amino acid sequence often cited in high-purity research catalogs.
Practical Considerations for Research Use
When selecting a CMV product, I always prioritize purity and documentation. Whether you are using a 1-sample peptide microarray or a custom-synthesized peptide for stimulation assays, the quality of the synthesis determines the reliability of your data.
The amino acid residues 13 to 27 of the 65k lower matrix phosphoprotein are frequently examined to understand how the human cytomegalovirus pp65 peptide interacts with host systems. It is fascinating to see how the cytomegalovirus pp65 continues to be a central entity in virology. By fo by G Li Pira·2004·Cited by 54—A selectedpeptidelibrary derived from thepp65 sequencecan stimulateCMV‐specific T cells that maintain specificity for the protein antigen, as proposed here Read more cusing on variables like the CMVpp65 concentration and the specific sequence length, researchers can achieve high-fidelity results that contribute to a deeper understanding of this complex organism.
In summary, whether you are dealing with the broad coverage of a peptide p Antigen Peptide CMV pp65 - HLA-A*0201 (NLVPMVATV) ool or the precision of an HLA-A*0201-restricted epitope, the study of cytomegalovirus pp65 remains a highly technical and rewarding endeavor. Always verify the uniprot status and purity levels of your reagents to ensure your experiments are as robust as possible.
