Custom peptides,
synthesized and
validated

Fmoc solid-phase synthesis and full analytical validation — from single fragments to complex multi-residue constructs. Every lot ships with RP-HPLC, LC-MS, and a Certificate of Analysis.

Capabilities

Synthesis and validation,
in one workflow

Assembly and analysis run under a single quality framework — so identity, purity, and documentation are produced together, and released together.

GEN-01Active

Peptide synthesis

Fmoc-based solid-phase synthesis of linear and modified peptides — from short fragments to long, difficult sequences, with coupling monitored at each step.

GEN-02Active

Analytical validation

RP-HPLC purity profiling and ESI-LC-MS identity confirmation — delivered with a Certificate of Analysis and a complete batch record for every lot.

GEN-03Active

Research catalog

Frequently requested research-grade peptides, produced to consistent parameters so that a repeat order reproduces the batch before it.

GEN-04Active

Production & supply

Scale-up within the same validated parameters — supporting continuity of supply without drift between lots.

Quality framework

We prioritize documentation over claims.

Every production cycle runs within defined parameters and predefined acceptance criteria. When a batch leaves the laboratory, its identity and purity are already on record — not asserted afterwards.

Workflow

From sequence to
certified batch

A defined path from your specification to a validated construct, with a checkpoint at every stage.

STEP_01

Define

We capture your sequence, modifications, quantity, and purity target, then confirm feasibility and price within 24 hours.

STEP_02

Design

The synthesis route is planned for the sequence — resin, protecting groups, and coupling strategy chosen for fidelity and yield.

STEP_03

Synthesize

Solid-phase assembly runs under controlled conditions; each coupling is monitored, followed by cleavage and purification.

STEP_04

Validate

RP-HPLC and LC-MS confirm purity and identity. The peptide ships lyophilized, with its Certificate of Analysis.

and purity

Nothing ships on assumption. Each batch is characterized by mass and purity, and released only against its specification.
