Background

Details

protag-HiPur GST Agarose Beads are based on a high-affinity single-domain antibodies (sdAb) that are covalently immobilized on 4% cross-linked agarose beads. The sdAbs are attached via a flexible linker which guarantees a high accessibility of the sdAbs and largely eliminates batch-to-batch variations. Due to the single-chain nature of sdAbs and their covalent attachment, no "leakage" of light and heavy chains from IgGs is observed during elution with SDS sample buffer. protag-HiPur GST Agarose Beads thus feature high affinity and superior capacity for GST fusion proteins while showing negligible non-specific background. protag-HiPur GST Agarose Beads are compatible not only with physiological buffers but also with high stringency buffers. With protag-HiPur GST Agarose Beads the binding and washing conditions can be adjusted to the experimental needs.
