Peptide Tools to Study HCMV

About Human Cytomegalovirus

HCMV or HHV-5 belongs to the family of Herpesviridae and is known to establish latency in leukocytes. At least 40% of adults worldwide have been exposed to HCMV. Whereas it is typically unnoticed in healthy individuals, HCMV infection can become life-threatening for high-risk groups such as pre- and postnatal infants or immunocompromised individuals e.g HIV-infected patients and organ transplant recipients. Therefore, these individuals require regular immune monitoring to detect acute HCMV infections.

HCMV in Research

Studies in humans and animal models have demonstrated a critical role for both CD4+ and CD8+ T-cell immunity in limiting viral replication and preventing the clinical manifestations of progressive infection. Many studies focus on pp65 for general immune monitoring. However, other antigens can be immune relevant and are often investigated in HCMV vaccine development. Furthermore, HCMV specific humoral immune responses have been reported and correlated to viral load.

  • Evaluation of co-infection
  • Detection of epitopes and epitope spreading

Catalog RepliTope™ Peptide Microarrays
Ready-made peptide microarrays displaying overlapping peptides through single immunodominant antigens:
IE-1, IE-2, pp65, UL28, UL32, UL36, UL40, UL48, UL55, UL82, UL86, UL94, UL99, UL103, UL151, UL153, US3, US24, US29 and US32.

RepliTope™ Antigen Collections
• The RepliTope™ Antigen Collection combines all 20 proteins above on one microarray for optimal coverage of the most important antigens in a single experiment.

Peptide ELISA

In addition to high-content peptide microarrays, JPT offers the development of peptide based enzyme-linked immunosorbent assays (ELISA). This common analytical and highly sensitive immunological assay is well established for proteins but requires detailed experimental know-how for peptides. Peptide ELISA is offered as stand alone service for mapping of epitopes and definition of protein interaction sites or as validation assay to confirm results obtained with JPT’s peptide microarrays.

Clinical Peptides

Clinical Peptides

JPT’s Clinical Peptides product lines GxP and ISO Plus are produced in production environments that are regulated by an enhanced ISO 9001:2015 quality management system for the stringent product requirements of immunotherapy as well as vaccine and drug development. Depending on the specifics of the immunotherapy concept to be applied, the resulting products have been shown to be applicable in clinical applications.

“I have been collaborating with JPT for several years. Their unique peptide library technologies and knowledge of specific peptide requirements for T-cell assays made them a valuable, long-termpartner in our efforts to develop novel adoptive immunotherapy approaches to prevent and treat viral infections post-transplant as well as for the treatment of virus and non virus-associated malignancies. Furthermore, their reagents allow us to precisely monitor and track specific T-cell populations post-infusion.”
Ann M. Leen, PhD, Baylor College of Medicine, Center for Cell andGene Therapy, Houston, USA.

“Over the past five years my research team has been active in the development of species-specific peptide arrays. Our ability to advance this technology into new research areas has been dependent on working with the highest quality of arrays. In this regard, JPT’s commitment to excellence has been a critical foundation for the success of our research program. I have been consistently impressed with their customer service, technical expertise and professionalism. When it comes to peptide work there are no other options for our group… JPT is the best.”
