Agere Sciences

What we make

Custom peptide synthesis

Design-to-delivery synthesis of simple to highly complex sequences, including difficult, hydrophobic, or long-chain peptides. Available as research-grade or GMP-ready material.

Linear, cyclic, and modified peptides

Support for a broad range of architectures, including cyclic peptides, stapled peptides, and targeted post-translational modifications (phosphorylation, acetylation, glycosylation, etc.).

Peptidomimetics and conjugates

Design and synthesis of peptidomimetics, PEGylated peptides, lipidated peptides, and conjugates (e.g., fluorophores, biotin, ADC linkers, targeting moieties).

Libraries and fragments

Peptide libraries, overlapping fragments, and truncated or alanine-scan series to support SAR, screening campaigns, and mechanism-of-action studies.

How we work

1 Small-scale R&D to large-scale production

Flexible scale options from milligram discovery quantities to multi-gram and kilogram manufacturing, enabling a smooth transition from screening to preclinical and clinical supply.

2 Method development and scale-up

Collaborative process development, route optimization, and tech transfer support to ensure robust, scalable, and cost-effective manufacturing.

Quality & documentation

High-purity manufacturing

High-purity peptides produced using controlled, validated processes with robust in-process controls.

Full analytical package

Comprehensive characterization packages available, including HPLC, LC–MS, HRMS, NMR (where applicable), and additional release testing on request.

ISO-certified facilities

Manufacturing performed in ISO-certified facilities with quality systems designed to align with regulatory expectations for therapeutic and diagnostic applications.
