JPT Peptide Technologies' PepSpots™ Peptide Arrays on cellulose membranes are synthesized with the unique SPOT technology (SPOT peptide synthesis technique). SPOT technology is a fast and economic technique for parallel custom peptide synthesis on membrane supports. SPOT peptide synthesis was developed to give rapid and low-cost access to large numbers of custom peptides both as membrane bound peptide arrays (PepSpots™) based on cellulose membranes for efficient and inexpensive B-cellantibody epitope mapping, protein-protein interaction studies etc. and as soluble peptide libraries (Micro-Scale Peptides and PepTrack™ Peptide Libraries). PepSpots™ peptide arrays are reliable and combine an easy experimental procedure, inexpensive equipment needs and a highly flexible array and library formatting. Subsequently, the mapped epitopes can be functionally characterized on the cellulose peptide array by rapid determination of key residues playing a definite role in the binding process. More than 100 scientific papers describing the application of this PepSpots™ peptide array technology and the hundreds of successful epitope mapping and epitope characterization projects performed at JPT over the last decade distinguish PepSpot™ peptide arrays as the method of choice for fast and reliable antibody epitope mapping and characterization.
"Our teams at the Vrije Universiteit Brussel deal with a wide variety of projects in different areas of applied biological sciences. For many of them we are in need of peptide related tools and services ranging from peptide libraries and highly purified peptides to peptide arrays. In our search for an integrated and reliable provider we came across JPT. Meanwhile, we are collaborating with JPT for many years and are very satisfied with the relationship which led to several well received publications. Especially, their unique array technology helped us to enhance our knowledge on different protein protein interactions such as Chaperone-substrate recognition."
