Creative Peptides, with its expertise in peptide services and products, offers customized sequencing and mixing protocols to meet your specific requirements, as well as quality reports such as pre-pooled LC-MS validation and post-pooled labeled peptide validation for you to choose from. Post-pool labeled peptides have unique and distinguishable characteristics and can be used to verify that the desired peptide has been added to the corresponding peptide pool system.
Peptide pools are clusters of immunostimulatory antigens, which are large collections of small peptides of specific lengths and different sequences. It consists of arrangements and combinations of various (or most) amino acid sequences in short peptides of that length, and is suitable for T cell stimulation of HIV, HCV, influenza, and other infectious diseases. It can be used for drug design, protein-protein interactions, biochemistry and pharmaceutical applications. Peptide pools are built based on small peptides containing key residues (mimic antigenic determinants clusters on proteins) as well as protein-protein interactions and recognition (interactions between local peptide fragments).
Creative Peptides' services for synthesizing peptide pools include standard, enhanced, and trace peptide pools, as well as sequence analysis, solubility testing, and more.
Customized Peptide Pool
Peptide Pools Synthesis
First, the desired peptide sequences need to be designed according to the purpose of the experiment. These sequences can be linear, cyclic, or contain modifying groups. Next, amino acid residues are added stepwise by solid-phase synthesis and peptide chains are formed by activation, coupling and deprotection. The prepared peptide chains are then collected together, either by physical mixing or by using branching protection during the synthesis process, resulting in the formation of peptide pools.
Peptide Sequence Analysis
Synthesized peptide pools are subjected to sequence analysis to ensure quality and purity. Commonly used methods include high performance liquid chromatography (HPLC) and mass spectrometry. By performing sequence analysis on all peptides (up to 200) in the entire peptide pool, it can be determined that the peptide pool contains all designed peptide sequences. This analysis is applicable to peptide pools used in target screening, antigenic epitope screening, and can further ensure that core sequences are not lost.
Dissolution Testing Services
Customized solubility testing of peptide pools is performed to confirm the appropriate solubility of the mixed peptide pools, with either the default solvent or a customized solvent selected directly.
Endotoxin Testing Services
Provide endotoxin analysis for peptide pools to assess whether the endotoxin level is suitable for the corresponding experiments.
Peptide pools are combinations of short peptides with different sequences, designed to mimic antigenic determinants or key protein regions. They are used in various research applications, including T cell stimulation in infectious disease studies, drug development, protein-protein interactions, and antigenic epitope screening.
Peptide pools are synthesized using solid-phase peptide synthesis, where amino acid residues are added step by step to form peptide chains. The designed peptide sequences are mixed together after synthesis to form the peptide pool, and the quality and purity of the pool are then validated using techniques like HPLC and mass spectrometry.
Creative Peptides offers three types of peptide pool synthesis: standard peptide pools, which include COA, MS, and HPLC data for each peptide; enhanced peptide pools, which provide LC-MS detection of labeled peptides in the pool; and trace peptide pools, which are more cost-effective and suitable for initial screening and proteomics applications.
We ensure the quality and purity of peptide pools by using advanced techniques such as HPLC and mass spectrometry. These methods help us confirm that the peptide pool contains all the required sequences and meets the necessary standards for your experiments.
Solubility testing ensures that the peptide pool dissolves properly in the selected solvent, which is crucial for maintaining the peptide's stability and functionality during experiments. Customized solubility testing is provided to ensure optimal performance of the peptide pool.
Endotoxin testing is necessary to ensure that the peptide pool does not contain harmful endotoxins, which could interfere with experiments. This step is particularly important for sensitive assays to maintain the integrity of your results.
Peptide pools are widely used in research for applications such as antigenic epitope screening, proteomics, target screening, and vaccine development. They are also valuable for studying protein-protein interactions and accelerating the drug discovery process.
Yes, Creative Peptides allows full customization of peptide pools. You can select peptide sequences based on your specific research requirements, whether they are linear, cyclic, or contain modifications, ensuring that the peptide pool aligns with your experimental goals.
