Ubiquitin K48 Selector is based on a high-affinity single-domain antibody (sdAb) that is covalently immobilized on 4% cross-linked agarose beads. The innovative, oriented and selective attachment via a flexible linker 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. The Ubiquitin K48 Selector specifically recognizes the lysine 48 linkages in polyubiquitin and will only precipitate polyubiquitin chains when this particular linkage is present.
