Custom peptide synthesis Australia services cover purity grades, turnaround times, and pricing for research labs. Compare local and overseas suppliers here.
Custom peptide synthesis in Australia is a made-to-order laboratory service: you send a sequence, an Australian provider builds it using solid-phase peptide synthesis (SPPS), and it ships back as lyophilized powder with a certificate of analysis. Most local providers serve universities, biotech companies, and diagnostic labs, and all of it is supplied for research use only. A peptide synthesized in Australia is not automatically TGA-approved for human use.
What Australian Peptide Synthesis Services Typically Cover
Most providers quote a base price by peptide length, synthesis scale, and purity grade, then add line-item charges for any modifications.
- Length: 5 to 40 residues is routine; 50+ residues usually needs fragment condensation or a custom quote.
- Scale: 1 mg, 5 mg, 10 mg, 25 mg, and 100 mg are common sizes, with 1 g and up available on request.
- Purity: crude or desalted, >70%, >95%, and >98% by HPLC.
- Modifications: N-acetylation, C-amidation, biotinylation, phosphorylation, cyclization, D-amino acids, and fluorescent labels such as FITC or FAM.
- Documentation: HPLC trace, mass spectrometry data, certificate of analysis, and a handling and solubility note.
Small pilot libraries are also available from many labs. Modern peptide synthesis chemistry is well established, so the variables that move your quote are sequence difficulty and purity target, not the underlying method.
Purity Grades, Scale, and Rough Australian Pricing
Real quotes vary with length, scale, and modifications, but the table below shows the ranges Australian labs typically publish. These figures are per peptide, in Australian dollars, and some quotes exclude GST.
| Purity (HPLC) | Common research use | Typical price range (AUD) |
|---|---|---|
| Crude / desalted | Screening, epitope mapping | $80–$200 |
| >70% | Polyclonal antibody production | $150–$350 |
| >95% | ELISA, immunoassays, cell culture | $250–$600 |
| >98% | Receptor binding, in vivo animal research | $400–$1,200+ |
Longer peptides, multiple cysteines, and non-natural residues push prices up quickly. A 30-mer with two disulfide bonds can cost several times more than a 12-mer at the same purity.
How Long Does Custom Peptide Synthesis in Australia Take?
Typical turnaround for a standard 10 to 20 residue peptide at 5 to 25 mg is roughly 5 to 10 business days from many Australian labs. Difficult sequences take longer, sometimes 2 to 4 weeks.
Sequences that slow an order down include:
- Long hydrophobic stretches or beta-sheet-prone regions
- Runs of glycine, alanine, or proline
- Multiple cysteines that require oxidation or disulfide mapping
- Peptides longer than about 30 residues
- Unusual labels that must be ordered in
Ask for a firm quote with a stated delivery window before ordering, and confirm whether the lab synthesizes in Australia or forwards the job to an overseas site.
Australian Labs vs Overseas Suppliers
Price and speed trade off differently depending on where a peptide is made. Research groups frequently weigh local providers against custom peptide synthesis china, custom peptide synthesis india, and custom peptide synthesis germany to balance budget against deadline.
| Supplier option | Main advantages | Main trade-offs |
|---|---|---|
| Local Australian labs and university core facilities | Fast domestic shipping, no customs clearance, easy reorders, local technical support | Higher cost per milligram, fewer exotic modifications |
| Chinese contract manufacturers | Lowest cost per milligram, large scales, high throughput | Variable QC, longer freight, documentation may need chasing |
| Indian CROs and CDMOs | Competitive pricing, expanding custom capacity | Quality varies by vendor, shipping and border time |
| German suppliers | Strong documentation and reliable purity claims | High prices, longer freight to Australia |
Groups that synthesize in-house buy resins, building blocks, and labels from reagent vendors. Catalog listings such as custom peptide synthesis thermo fisher and novabiochem peptide synthesis cover the consumables side of the workflow rather than finished peptides.
When comparing vendors, request a lot-specific certificate of analysis instead of a generic sample. Peptide content, counter-ion, and water content all affect how much usable peptide you actually receive.
Importing Peptides Into Australia: Customs and Compliance
Research peptides imported into Australia are usually treated as laboratory chemicals, but that is not guaranteed for every sequence. Some peptides are listed in the Poisons Standard as prescription-only or controlled, and those need permits regardless of labeling.
- Expect GST and possible customs clearance fees on overseas orders.
- Allow an extra 3 to 10 business days for border processing.
- Check the Poisons Standard (SUSMP) and your institution's requirements before ordering.
- Keep supplier paperwork, safety data sheets, and certificates of analysis on file.
Never assume that a research-use-only label makes a peptide legal or safe for human consumption. It does not.
Checklist for Choosing a Peptide Synthesis Provider
- Lot-specific COA with an HPLC trace and mass spectrum.
- Mass confirmed within about 1 Da of the theoretical value.
- A stated purity method, such as HPLC area percent at 214 nm.
- Clear handling, storage, and solubility guidance.
- A defined turnaround time and a reship policy for failed QC.
- Demonstrated experience with your specific modification.
If a supplier cannot provide a mass spectrum for the exact lot shipped, treat the purity claim as unverified.
Safety, Legal Status, and What Research Peptides Are Not
Custom-synthesized peptides sold for laboratory use are not medicines. The Therapeutic Goods Administration has not approved most peptides marketed online for human use, and 98% purity does not mean a peptide is safe to inject or swallow.
If you are considering any peptide for a health condition, talk to a qualified doctor or pharmacist rather than relying on supplier marketing. Self-administered research chemicals carry real risks, including contamination, incorrect dosing, and unknown interactions with prescription medicines.
Frequently Asked Questions
How much does custom peptide synthesis cost in Australia?
Most Australian labs charge roughly $150 to $600 for a standard 10 to 20 residue peptide at over 95% purity in 5 to 25 mg quantities. Crude and desalted batches cost less, while over 98% material and peptides with labels or disulfide bonds cost more. Always request a firm quote, because published catalog prices rarely match a custom sequence.
How long does custom peptide synthesis take in Australia?
A routine 10 to 20 residue peptide usually ships in about 5 to 10 business days from an Australian lab. Sequences with hydrophobic stretches, multiple cysteines, or more than 30 residues can take 2 to 4 weeks. Overseas suppliers add international shipping and customs clearance time on top of the synthesis window.
Is it legal to buy custom peptides in Australia?
Research-grade peptides are generally legal to purchase and import for laboratory use in Australia, but some sequences are controlled under the Poisons Standard and need permits. Peptides intended for human therapeutic use must be TGA-approved, and most custom peptides are not. Check the current Poisons Standard and your institution's policies before placing an order.
