Standard & modified peptides
Specify the sequence and modifications such as terminal changes, phosphorylation, biotin or fluorescent labels.
PEPTIDE SYNTHESIS
Peptide synthesis
Your sequence. Quality you can review.
From standard sequences to modified, labeled and cyclic peptides. Tell GENonLAB your purity, quantity and aliquot requirements for GenCefe feasibility review and quotation.
Consultation, quotation & order coordination: GENonLAB · Synthesis & analysis: GenCefe Biotech
DESIGNED FOR YOUR RESEARCH
Custom synthesis for your research
Cyclic & specialized structures
Discuss cyclization sites, disulfide bonds, non-natural amino acids and other structural requirements.
Libraries & isotope labeling
Discuss multi-sequence screening libraries and stable isotope-labeled peptides.
Feasibility depends on sequence length, hydrophobicity and modification combinations. Specialized requirements are reviewed before order confirmation.
QUALITY YOU CAN REVIEW
Two complementary quality checks
HPLC
High-Performance Liquid Chromatography assesses purity. Review the chromatogram together with the analytical conditions.
MS
Mass Spectrometry checks molecular weight. Compare the measurement with the theoretical mass of the requested sequence and modifications.
Delivery & documentation
GenCefe describes HPLC and MS testing with Quality Control (QC) documentation for each peptide. The standard format is lyophilized powder; confirm final purity, quantity, aliquots and documentation with your quotation.
Purity and mass confirmation do not guarantee activity in a particular assay. Discuss any required functional testing in advance.REQUESTED SPECIFICATIONS
Choose your specifications
These options describe your requested specifications. Feasibility, final quantity and purity, price and lead time are confirmed after sequence and modification review.
Manufacturer-published capabilities include up to 180 amino acids, milligram-to-gram scales and purity above 98%. These are not guaranteed for every sequence; requirements outside the form options are reviewed individually.
A BETTER BRIEF, A CLEARER QUOTE
Prepare these six details
Sequence & direction
Provide the sample name and one-letter sequence from the N (amino) terminus to the C (carboxyl) terminus.
Research objective
Describe the intended use, such as antigen preparation, binding analysis or cell experiments.
Quantity & purity
Specify milligrams and target purity for each sequence. Undecided requirements can be discussed during consultation.
Modification & position
Provide original notation for terminal changes, labels, cyclization sites and special amino acids.
Aliquots & additional processing
Specify vial count, amount per vial, desalting and endotoxin-removal needs. Acceptance criteria and feasibility require separate confirmation.
Timing & delivery
Provide the required arrival date and delivery format. Domestic arrival includes manufacturing, international transport and customs clearance.
AFTER DELIVERY
Handle your peptide with care
Aliquot to limit freeze–thaw
Prepare aliquots for individual experiments. Follow product-specific storage temperatures and expiry guidance, and avoid prolonged storage in solution.
Limit air & moisture exposure
Sequences containing cysteine (Cys), methionine (Met) or tryptophan (Trp) need protection from oxidation. Let the sealed vial reach room temperature before opening to reduce condensation.
Test solubility on a small amount
Check the product-specific solvent recommendation first. Without specific instructions, test a small amount in water and discuss a suitable solvent if dissolution is poor.
Dimethyl Sulfoxide (DMSO), other organic solvents, acids and bases are not interchangeable across all sequences. Check oxidation sensitivity, final solvent concentration and assay compatibility before use.

QUESTIONS, ANSWERED
Questions before you order
Can I inquire before finalizing a sequence?
Yes. Start with your objective, approximate length, quantity, purity, modifications and timing. Submit the online form once the specifications are defined.
Which purity should I choose?
The choice depends on your assay and tolerance for impurities. Higher purity can change purification difficulty and cost; include your experimental requirements.
Does submission start production?
No. GENonLAB reviews your requirements and provides a quotation, schedule and terms before the order is confirmed.
What documents accompany delivery?
Purity and mass analysis are the core documentation. Confirm per-sample reports and additional analyses at quotation; biological activity or functional testing requires prior agreement.
