The PSBinder is a predictor that can be used to predict if your peptide are polystyrene surface-binding peptide (PSBP) or not. The predictor was built using Support Vector Machine. PSBP are useful as affinity tags to build high effective ELISA systems. However, they are also a quite common type of target-unrelated peptides in the panning of phage-displayed random peptide library. Please enter peptides in FASTA or raw sequence format. (Download standalone tools on the Download page.)

Pay attention: the threshold to distinguish between predicted positives and negatives (tp) ranges from 0 to 1. However, it is set to 0.5 by default. That is to say, a peptide will be predicted to be a PSBP if the probability is 0.5 or higher. You can adjust the threshold according to your own needs. For instance, you should set a lower tp if you do not care about false positives and just want to exclude all possible PSBPs. On the contrary, you should increase the tp to 0.95, for example, if your purpose is to discover some novel PSBPs with greater confidence. Here we go!
