Target description

Selenoprotein P (UniProt: P49908; also known as SeP) is encoded by the SELENOP (also known as SELP, SEPP1) gene (Gene ID: 6414) in human. Selenoprotein P is a secreted glycoprotein that is synthesized mainly in the liver and secreted into the plasma. It contains most of the selenium in plasma. It is synthesized with a signal peptide (aa 1-19), which is subsequently cleaved off in the mature form. Secreted form of selenoprotein P is made up of two domains. The larger N-terminal domain contains one selenocysteine (U) in a U-x-x-C redox motif and the shorter C-terminal domain contains nine selenocysteines. It is shown to bind to heparin in a pH-sensitive manner at the heparin-binding site in its N-terminal region that contains two histidine residues that become protonated, and therefore can bind heparin. Selenoproteins provide a key defense against oxidative stress, as many of these proteins participate in oxidation-reduction reactions neutralizing reactive oxygen species, where selenocysteine residues act as catalytic sites. Selenoprotein P is removed from plasma by glomerular filtration by endocytosis mediated by LRP2 in the proximal tubule epithelium. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.


300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
