T7 Phage Display Peptide Library Construction Platform
Alpha Lifetech has accumulated rich experience and technology in the construction of T7 phage display peptide library. They provide a variety of peptide library construction services based on T7 bacteriophage, including random 7-peptide library, 12-peptide library and cyclic 7-peptide library. These peptide libraries are widely used in proteomics, immunotherapy, vaccine development, drug discovery, target verification and epitope localization.
The role of T7 phage display peptide library
The role of solid phase peptide synthesis in T7 phage display peptide library
Verifying the diversity of peptide libraries
Solid phase peptide synthesis is an efficient and widely used technology. By gradually adding amino acids to solid supports, high-purity peptide molecules can be rapidly synthesized. Peptide candidates screened from T7 phage display peptide libraries often need to be synthesized by solid phase peptide synthesis to verify their structure and activity.
Optimization of peptide function
Using solid phase peptide synthesis technology, the peptide function obtained by screening can be optimized by point mutation or gradual extension of peptide fragments to make it more suitable for target binding or improve stability.
Binding force test
Solid phase peptide synthesis provides technical support for the verification of peptide-target binding in T7 phage display peptide library. For example, the selected peptides were prepared by solid-phase synthesis, and then their binding force with the target molecule was tested.
The role of liquid phase peptide synthesis in T7 phage display peptide library
Preparation of complex peptides
Liquid phase peptide synthesis is a synthesis method suitable for long-chain or complex modified peptides. In the optimization process of T7 phage display peptide library, some special peptides ( such as cyclic peptides or modified peptides ) can be synthesized by liquid phase peptide synthesis.
Analysis and quality control
The peptides screened by T7 phage display can be prepared on a large scale by liquid phase peptide synthesis method, and then analyzed by liquid chromatography and other methods. This provides accurate quality verification for the screening results of peptide libraries.
Production scale application
Liquid phase peptide synthesis is particularly suitable for large-scale preparation of peptide molecules for subsequent experimental verification or drug development. In the downstream applications of T7 phage display technology ( such as drug development ), liquid-phase synthesis is an important production method.

Construction of T7 Phage Peptide Library Workflow
| Process | Service Content | Timeline |
|---|---|---|
| 1. Select A Phage Vector | Select suitable T7 phage vectors, which typically contain promoters, selective markers, and appropriate regulatory elements. | / |
| 2. DNA Fragment for Designing and Synthesizing Random Peptides | Depending on the study goal, the sequence of random polypeptides is designed, usually between 6 and 20 amino acids in length. The oligonucleotide fragments of these peptides were synthesized randomly by chemical synthesis method. | 1 week |
| 3. Insert A DNA Fragment of A Random Polypeptide Into A Phage Vector | DNA fragments of phage vectors and random polypeptides are cut using restriction enzymes to produce complementary sticky ends. The recombinant phage vector is formed by connecting the DNA fragments of random polypeptides with the phage vector by DNA ligase. | 1 day |
| 4. Transforming Host Bacteria | Transformation of recombinant phage vectors into host bacteria, such as E. coli. The phage vector was successfully replicated and expressed in bacteria by means of transformation methods such as electric transformation or heat shock. | 1 week |
| 5. Amplification and Screening of Phages | The host bacteria were amplified in selective media to produce a large number of recombinant phages. The phage was extracted and purified by centrifugation and filtration, and the high concentration peptide library was obtained. Affinity screening of target molecules (such as antibodies, receptor proteins, etc.) is used to screen phage clones that can bind to target molecules with high affinity from peptide libraries. | 1 week |
