Lipocalin-2/NGAL is a multifaceted iron transporter involved in multiple biological processes, including apoptosis, innate immunity, and kidney development. Lipocalin-2 dynamically affects cellular iron concentration through binding to the siderophore 2,3-dihydroxybenzoate. Lipocalin-2/NGAL Protein, Rat (sf9, His) is the recombinant rat-derived Lipocalin-2/NGAL protein, expressed by Sf9 insect cells , with C-His labeled tag.
