Ph.D.™-12 Phage Display Peptide Library

Product Introduction

The Ph.D.-12™ Phage Display Peptide Library contains a single tube of the Ph.D. -12 Phage Library. The Ph.D.-12 library is a combinatorial library of random 12-mer peptides fused to a minor coat protein (pIII) of M13 phage. The displayed peptide is expressed at the N-terminus of pIII. The library consists of approximately 109 electroporated (i.e., unique) sequences.

  • Ready to use complex phage library
  • Applications and methodologies are numerous and supported by over 20 years of literature citations
  • Does not require helper phage for amplification
  • Inherent link between phenotype and genotype allows screening of billions of clones in a single microtiter well or Eppendorf tube

Product Information

Description

The Ph.D.-12 Phage Display Peptide Library is based on a combinatorial library of random dodecapeptides fused to a minor coat protein (pIII) of M13 phage (1–6). The displayed peptide (12-mer) is expressed at the N-terminus of pIII, i.e., the first residue of the mature protein is the first randomized position. The peptide is followed by a short spacer (Gly-Gly-Gly-Ser) and then the wild-type pIII sequence. The library consists of approximately 109 electroporated sequences amplified once to yield approximately 100 copies of each sequence in 10 µl of the supplied phage.

FAQs & Troubleshooting

FAQs

  1. Which of the three ready-made libraries should I choose?
  2. What peptide libraries are available for use with Ph.D.™ Phage Display?
  3. I am using Ph.D.™ Phage display and the amplified phage titer is low.
  4. I am using Ph.D.™ Phage Display and the phage DNA templates do not yield a readable sequence.
  5. I am using Ph.D.™ Phage Display and the sequencing templates do not run where they should on a gel.
  6. I am using Ph.D.™ Phage Display and after 4 or more rounds of panning all clones are wild-type phage (white plaques).
  7. When performing an experiment using Ph.D.™ Phage Display, the ELISA indicates that background binding to the plate is as high as binding to the target.
  8. When using the Ph.D.™ Phage Display, panning yielded a consensus sequence, but no ELISA signal.
  9. I am using Ph.D.™ Phage Display and the streptavidin control experiment did not yield the HPQ consensus sequence.
  10. Can a different bacterial strain be used with the Ph.D.™ Phage Display?
  11. Where can I find references for Ph.D.™ phage display libraries?
