Analytical records
Testing, verificationand documentation.
All peptides are supplied with laboratory testing and undergo additional analytical verification by SPT upon receipt to confirm they meet our quality standards. Batch-specific Certificates of Analysis are published for transparency where the corresponding batch documentation is available. Material is supplied exclusively for in-vitro laboratory research use.

Protocol
The SPT testing protocol
- 01
Synthesis (manufacturing partner)
Solid-phase peptide synthesis (SPPS) performed in controlled environments using research-grade reagents.
- 02
Purification (manufacturing partner)
Reverse-phase HPLC purification to remove deletion sequences, truncations and byproducts.
- 03
Lyophilisation (manufacturing partner)
Freeze-drying to produce stable lyophilized powder for long-term storage and shipping.
- 04
Analytical verification on UK receipt
Material is checked by SPT on receipt to confirm it meets our quality standards before it is released to the catalogue.
- 05
Certificate of Analysis
Where a batch record has been published, its certificate appears on the corresponding product page and in the certificate library.
- 06
UK Dispatch
Vials are inspected, sealed in premium packaging and dispatched from the UK.
Additional analysis
Endotoxin Testing
Selected batches undergo bacterial endotoxin testing to measure endotoxin levels. When that analysis has been carried out, the result and its applicable limit appear on that batch’s documentation.
Separate from purity testing
Endotoxin testing is a distinct analysis from HPLC purity and mass-spectrometry identity testing. A batch with endotoxin data has been measured for endotoxin levels only — it does not change or replace the purity and identity results on the certificate of analysis.
What it does not mean
“Endotoxin Tested” indicates that a measurement was carried out on that specific batch. It does not by itself indicate sterility and does not imply suitability for human use. All material is supplied for in-vitro laboratory research use only.
Where a batch has no endotoxin data, no endotoxin marker is shown on that product or certificate.
