Neoantigen Peptide: a key piece of the puzzle for personalized immunotherapy that
Why is Neoantigen Peptide so hot?
Those who are doing tumor immunity know that neoantigen is a mutation product unique to tumor cells, which is not found in normal cells. Activating T-cells with neoantigens can theoretically only kill tumors and will not hurt innocent people. Therefore, no matter it is tumor vaccine or TCR-T therapy, everyone is chasing neoantigen.
But to go after a new antigen, you first have to get the peptide. That's what we do - Neoantigen Peptide Synthesis.
Neoantigen Peptide study, what's giving you headaches?
We've talked to many immunization teams and found that there are several common pain points:
There are too many candidate peptides: a patient may be screened for dozens or hundreds of mutation sites, each of which has to be synthesized and tested, and the workload is enormous.
Peptide length: Neoantigen Peptide is generally 15-25 amino acids, which is longer than normal short peptide, and it is difficult to synthesize.
Long lead time: Waiting for peptides takes longer than doing experiments, and project progress is dragged along.
Insufficient purity: cellular experiments require purity, and the results are unreadable if there are too many impurities.
Labeling is required: sometimes it is necessary to connect biotin and fluorescent groups, which cannot be done by ordinary synthesis companies.
Our Neoantigen Peptide synthesis service can take on these problems.
What we can do
1. High-throughput synthesis, several hundred at a time
The screening stage is fast. We have several automatic synthesizers and parallel synthesis systems, which can synthesize tens to hundreds of peptides in a single batch.
- Common needs: new antigen library of 96 peptides, delivered in 2-3 weeks.
- Flexible batching: one batch can be sent first to start the experiment, and the rest can be made up successively.
2.Purity on demand, from crude to ultra-pure
Requirements for purity vary depending on the stage of the experiment:
|
Purity level |
Applicable Scenarios |
Description |
|
Crude (70-85%) |
Initial screening, to see which ones are active |
Minimal cost, quick turnaround |
|
Conventional pure (85-95%) |
Most cellular experiments that |
Cost-effective, controllable impurities |
|
High purity (95-98%) |
Animal experiments, functional validation |
Low interference and reliable results |
|
Ultrapure (>98%) |
structural studies, special requirements |
Pure, slightly more expensive |
Each Neoantigen Peptide comes with HPLC and MS report, the purity is what it is, no false.
3. Modification of Neoantigen Peptide
Some experiments require that the peptide has a "function":
- Biotin markers:do affinity capture, tetramerization.
- Fluorescent labeling:FITC, TAMRA, Cy5, see how the peptide enters the cell.
- Phosphorylation modification:mimics the post-translational state.
- PEGylation: prolonged half-life, for in vivo experiments.
- Stapled peptide: Stabilizes conformation and enhances immunogenicity.
Why choose us for Neoantigen Peptide?
1. I've been doing peptides for 20 years, and I've seen all kinds of difficult ones
Neoantigen Peptide sounds new, but it is essentially peptide synthesis. Hydrophobic peptides, peptides that are easily aggregated, peptides with disulfide bonds, peptides that require special modifications - we have handled too many difficult peptides in the past 20 years. Therefore, we will help you to avoid the pitfalls of Neoantigen Peptide in advance.
2. High flux, also fast
Some customers are worried that if they order dozens of peptides at a time, will the batch be delayed for a long time? We have our own process, synthesis, purification, quality control are all smooth, 96 peptides of the standard library, 2-3 weeks to complete, in the middle of the need for you to rush. If there is an urgent project, we can deliver in batches, so that you can get up and running first.
3. The quality control is not fooled around, and each peptide is documented
What is the biggest fear of new antigen research? Wrong peptide sequence or impurities interfering with the experimental results. We insist:
MS was performed for each peptide to confirm that the molecular weights were correct.
Each peptide was subjected to HPLC and labeled with the amount of purity.
All data is supplied with the shipment and will be useful when you post articles.
4. Follow through from screening to preclinical
There are several phases of neoantigen research, all of which we can pick up:
Screening period: large number of candidate peptides, crude or conventionally pure, delivered quickly.
Validation phase: a few positives are screened out, requiring high purity for cellular assays.
Preclinical: Scale up to milligrams or even grams and do animal studies.
No need to change suppliers for the same project, eliminating the cost of interfacing.

Three real-life examples of how we help our clients
Case 1: The country's top oncology institute
The customer needed 120 Neoantigen Peptides of 15-20 amino acids for personalized vaccine screening. We delivered all of them in 2.5 weeks with purity >90%. They screened 5 positives with these peptides, and the follow-up work was published in Nature.
Case 2: American Biotechnology Corporation
They needed a batch of biotin-labeled MHC-peptide complex for TCR-T. We synthesized the high-purity peptide according to the sequence and completed the labeling. We synthesized the high-purity peptide according to the sequence and completed the labeling, the labeling efficiency was >95%, and the batch-to-batch consistency was good, so we helped them to do the tetramer smoothly.
Case 3: Preclinical Programs of European Pharmaceutical Companies
The client has sieved 3 Neoantigen Peptides, which need to be scaled up to 500mg for animal experiments. These three peptides are highly hydrophobic and difficult to synthesize. We optimized the solvent system and finally delivered >95% purity and 20% higher yield than they expected.
