Quality, testing and documentation
Reproducible research starts with knowing what is in the vial. UKPeps is built around that: every product is documented lot by lot, so you work with a known reference substance you can check. Everything below applies to laboratory research only.
Documentation for every product
Each product page gives the CAS number, the molecular data (molecular formula, molar mass and, where relevant, sequence) and a written specification. You know what you are ordering before it is dispatched.
Purity and independent testing
Our specification is at least 98% purity. The specification is what we require; what was actually measured is on the certificate of analysis for each lot, with the method, because our two laboratories measure differently. All values are open in the certificate library. For your vial, the figure that counts is the one for its lot, not a general claim.
Certificates of analysis
A certificate confirms identity and, where stated, purity at lot level. The library currently holds 82 certificates for 29 substances from APIGENEX s.r.o. and Liquilabs s.r.o.
Handling and storage
Products are supplied lyophilised (freeze-dried) for stability and stored at −20 °C. Orders are packed in plain, temperature-protected packaging and sent from UK stock. After reconstitution, solutions are kept at 2 to 8 °C.
A registered company
UKPeps is operated by UAB Nauja oda eshop, registered in Vilnius, Lithuania, company code 306079160. Payment is by UK bank transfer in pounds sterling or by cryptocurrency; orders are dispatched once payment is confirmed.
Questions

What purity do your peptides have?
Our written specification is at least 98%. The value measured for each lot, and the method used, are on that lot's certificate.
How are orders stored and shipped?
Lyophilised vials are stored at −20 °C and dispatched from UK stock in plain, temperature-protected packaging by Royal Mail Tracked 48.
Are these products for human use?
No. They are supplied exclusively for in vitro laboratory research.
