High Throughput Peptides
What is SPOT Synthesis?
The SPOT peptide synthesis technique is an ultra-high-throughput synthesis method for hundreds to thousands of peptides in parallel. Peptides are synthesized on a coated cellulose membrane that is used as solid phase. After synthesis peptides can remain on the membrane for an easy and inexpensive peptide array (PepSpots) or be separated from the mebrane and used as individual peptides (PepTrack Fast Track), pooled (SpotMix) or used to print on glass slides (PepStar).
This automated process results in the production of huge numbers of peptides making this a fast and economical alternative to other methods that aim for deep T- and B-cell epitope discovery, MS-based proteomics relying on heavy & light reference peptides, antigen target identification and others.
Our SPOT peptides come in many ready to use formats, which allow a broad application range for well-known experimental procedures with a robust readout.
