Here we show that traditional Sanger sequencing combined with analysis tools available from the European Molecular Biology Laboratory-European Bioinformatics Institute (EMBL-EBI), specifically EMBOSS Transeq and Clustal Omega, is extremely effective in the analysis of naïve phage display antibody libraries for the determination of library size and diversity. The free tools are easy to use and require little manipulation of reads by hand, allowing analysis to be performed on a standard personal computer. Utilization of this technique has applicability to researchers with limited access to deep sequencing. The primary drawback to this analysis methodology is that antibodies with particular molecular or binding properties, desirable or otherwise, are not identifiable by their sequences.
The authors would like to thank the Pearson Pond Ranch and Llama Co. for allowing llama blood collection. Timothy Kennell, Jr. performed some of the laboratory procedures.
