Our Solutions

    Capture and purification of insulin and insulin analogues

    Insulin Adsorbent, developed in collaboration with a leading insulin manufacturer, is a specialized affinity adsorbent tailored for human insulin, insulin analogues, and their precursors. This robust affinity resin features a proprietary, insulin-specific synthetic affinity ligand bonded to PuraBead® P6HF base matrix. It is commercially utilized in the production of various insulin forms, including rapid-acting and long-acting insulin types. Insulin Adsorbent is also effective for capturing and purifying single-chain insulin precursors. Like all PuraBead® resins, it is fully alkali-stable, enabling cleaning and sanitization with 0.5M or 1M NaOH, and it supports high flow rates, low back pressures, and extended operational lifetimes. Offering an environmentally friendly alternative to traditional HPLC methods, which often require solvent-based buffers, Insulin Adsorbent uses wholly aqueous buffers and provides a sustainable solution for insulin manufacturing.

    Purification of interferons with Mimetic Blue® SA

    Originally designed for purifying serum albumins, Mimetic Blue® SA resins are also effective for purifying interferons, including Interferon-α (INF-α) and Interferon-β (INF-β). These resins are highly durable, supporting high flow rates, low back pressures, and extended operational lifetimes. Additionally, Mimetic Blue® SA resins can be easily cleaned and sanitized using NaOH.

      Purification of recombinant proteins using PuraBead® IEX

      Ion Exchange (IEX) chromatography is a widely used technique for separating and purifying proteins based on their net charge differences. Astrea Bioseparations offers a comprehensive selection of robust, fully alkali-stable ion exchange resins. These resins are crafted from free-flowing, near-monodisperse PuraBead® base matrices, ensuring high binding capacities, prolonged operational lifetimes, high flow rates, and low back pressures. The selection of the optimal PuraBead® ion exchange resin and corresponding chromatography buffers is streamlined with our pre-packed RoboColumns® and IEX Selection Kits, which enable reproducible achievement of high yields of highly purified proteins.

      Purification of recombinant proteins using PuraBead® HIC

      Hydrophobic Interaction Chromatography (HIC) is frequently used to purify proteins based on their hydrophobicity or polarity differences. Astrea Bioseparations offers an extensive selection of robust, fully alkali-stable hydrophobic interaction resins derived from free-flowing, near-monodisperse PuraBead® base matrices. These resins ensure high binding capacities, extended operational lifetimes, high flow rates, and low back pressures. The process of selecting the optimal PuraBead® HIC resin and chromatography buffers for specific applications is simplified with our pre-packed RoboColumns® and HIC Selection Kits, which enable reproducible achievement of high yields of highly purified proteins.
