Technical guidance
Storage and capability specifications. Lot-specific values — exact mass, purity, endotoxin — are on each lot’s COA, which governs.
Storage & handling
Lyophilized, unopened
Store at −20 °C, desiccated and protected from light. Stable ≥24 months from the COA release date.
Reconstituted
Aliquot immediately and store at −80 °C. Avoid freeze–thaw cycles; use working aliquots within 30 days.
On the bench
Keep solutions on ice. Most sequences tolerate ≤4 h at room temperature; cysteine-containing peptides less.
In transit
We ship lyophilized on dry ice with 48 h of margin; a temperature logger is included on request.
Synthesis capabilities
Solid-phase synthesis (Fmoc SPPS) with preparative RP-HPLC purification. Outside these ranges, ask — long or aggregation-prone sequences are quoted case by case.
| Parameter | Range |
|---|---|
| Sequence length | 2–60 residues |
| Scale | 1 mg – 10 g per lot |
| Purity tiers | ≥95% · ≥98% · ≥99% (RP-HPLC) |
| Modifications | N-acetylation, C-amidation, disulfide bridges, PEGylation, biotin, fluorophores (FITC, TAMRA) |
| Counter-ions | TFA (standard), acetate, HCl |
| Formats | Bulk lyophilizate or vialed 1/5/10 mg |
Lot documentation governs
Where this page and a lot’s certificate of analysis disagree, the COA is correct. Verify any vial by scanning its QR code.
