peptide library

As validated by quality control DNA sequencing, more than 97% of randomly picked clones from these two libraries contained dsDNA inserts, and only an insignificant percentage of them harbored longer or shorter diversified peptides. None stop codons were founded as expected. Also, there was no single nucleotide deletion or insertion detected; importantly, non-sense frame-shift mutation was completely absent, demonstrating the beauty of trimer-codon strategy. Moreover, no Cys encoding codon was identified in the peptide library as designed. These Random Peptide Libraries are the best random 16-mer and 20-mer peptide libraries in terms of their quality and diversity.
