Peptide Tools for HIV Research
About Human Immunodeficiency Virus
HIV is a retrovirus that causes acquired immuno-deficiency syndrome (AIDS). This progressive collapse of cellular immune response renders commonly harmless infections and cancers to become severe. They are caused by pathogens such as Candida, M. tuberculosis or latent herpes viruses (e.g. EBV, HCMV). In infected individuals, HIV is present as free particles and in infected immune cells (specifically CD4+ cells). Entry of HIV into cells requires the interaction of the viral envelope protein gp120 with the CD4 glycoprotein and a chemokine receptor on the host cell surface.
HIV in Research
Development of a potential vaccine is an important goal to AIDS researchers. Immune correlate analysis of the largest clinical trial so far (RV144 or Thai trial) was performed with the help of JPT’s RepliTope™ Antigen Collection HIV Microarrays. The results showed that the presence of IgG against the V2 loop of gp120 is highly correlated with reduced risk of infection. Other vaccination strategies aim to stimulate specific cytotoxic T-lymphocytes.

HIV Ultra PepStar™ Peptide Microarray
JPT’s HIV Ultra microarray displays overlapping peptide scans through HIV gag p17 and p24, tat, nef, env and the remaining immunogenic regions of the HIV proteome (6564 15mer peptides). It covers sequences from the most frequent clades (A, B, C, D, G, CRF1, CRF2) of HIV 1. We also offer our assay and analysis service using your samples with this high-content HIV peptide microarray.
Tailored PepStar™ Peptide Microarrays
You define content and layout, we provide economic and fast production in our regulated clean-room environment. We also offer our assay and analysis service using your samples with your tailored peptide microarray.
Our tailored Peptide ELISA plates are 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
JPT’s Clinical Peptides product lines Clinical Grade 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.
