Recombinant human HSP90β (Human Heat Shock Protein 90 beta), encompassing amino acids 527-724(end). This construct contains an N-terminal His-tag (6xHis) followed by an Avi-tag™. The recombinant protein was enzymatically biotinylated at the C-terminal using Avi-Tag technology and affinity purified. Biotinylation is confirmed to be ≥90%.
