  • HPLC & UHPLC Columns - Robust and Reproducible Analysis

    TSKgel® columns are designed for researchers seeking the highest level of performance. Since the introduction of the first SEC column in 1971, TSKgel columns became increasingly popular in biotechnology and biopharma. Covering the total range of UHPLC, HPLC and SEC, these columns offer high resolution, excellent reproducibility, and long column life.

    TSKgel HIC-ADC Columns

    TSKgel hydrophobic interaction chromatography (HIC) columns are widely used for analyzing the drug-to-antibody ratios (DARs) in ADCs (antibody-drug conjugates). The new TSKgel HIC-ADC column line features a novel particle technology with increased uniformity and increased ligand density relative to traditional HIC columns.

    Bioprocess Media, Columns, and Instruments Highest purity from lab to production

    TOYOPEARL®, Ca++Pure-HATM, and TSKgel® chromatography media are specifically designed to purify biomolecules such as therapeutic peptides, proteins, antibodies, and oligonucleotides at lab, pilot, and commercial scale. A choice of process development tools such as our range of SkillPakTM pre-packed columns facilitates the development of robust and efficient purification methods. The OctaveTM MCC solutions help achieving superior productivity levels and cost reduction via multi-column chromatography.

    TOYOPEARL Super A Resin

    Downstream processing (DSP) of monoclonal antibodies (mAbs) requires an efficient purification process to achieve high product purity. The most important aspect of mAb purification, the capture step, is usually performed with a Protein A chromatography resin, since this alone can achieve >95% purity. To successfully support biopharmaceutical manufacturing, Protein A resins must offer exceptional performance. The new TOYOPEARL Super A resin provides superior dynamic binding capacities and HCP reduction at mild elution pH conditions.

    Octave MCC Instruments

    Multi-column chromatography (MCC) represents a significant advancement in separation and purification techniques. MCC employs multiple smaller columns in a synchronized, continuous cycle. Each column can be used in a different phase of the purification process, enabling simultaneous loading, washing, elution, and regeneration. This dynamic operation results in resin savings, reduced buffer usage, faster processing, and a significantly smaller equipment footprint than traditional systems. The Octave MCC instruments and SkillPak pre-packed columns are part of a holistic approach to achieve superior productivity levels via multi-column chromatography and cost reduction.
