Peptide synthesis & research supply

Built for
rigor, not
shortcuts.

"The strength behind scientific research."

Every lot is synthesized, purified, and independently verified before release. No compound ships without a certificate of analysis attached to its batch number.

Quality control

The six labors

Named for the standard every batch has to clear before release — not a metaphor, the actual pipeline.

01
Synthesis
Solid-phase peptide synthesis under controlled reaction conditions, batch-logged from first coupling to cleavage.
02
Purification
Preparative HPLC isolates the target sequence from truncation and deletion byproducts.
03
Identity confirmation
Mass spectrometry confirms molecular weight against the expected sequence mass.
04
Purity assay
Analytical HPLC generates the purity percentage published on that lot's certificate.
05
Sterility & endotoxin screen
Each lot is screened for bioburden and endotoxin level prior to release.
06
COA & release
Results are compiled into a signed certificate of analysis tied to the lot number on the vial.
