ORM2 Protein, Human, Recombinant (His Tag) Product Information
> 90 % as determined by SDS-PAGE
< 1.0 EU per μg of the protein as determined by the LAL method
Testing in progress
A DNA sequence encoding the human ORM2 (P19652) (Met1-Ser201) was expressed with a polyhistidine tag at the C-terminus.
Predicted N Terminal
The recombinant human ORM2 consists of 194 amino acids and predicts a molecular mass of 23.1 KDa. It migrates as an approximately 23 KDa band in SDS-PAGE under reducing conditions.
Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us
for any concerns or special requirements.Please refer to the specific buffer information in the hard copy of CoA.
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Stability & Storage
Samples are stable for up to twelve months from date of receipt at -70℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

ORM2 Background Information
ORM2 belongs to the calycin superfamily, lipocalin family. Lipocalins share limited regions of sequence homology and a common tertiary structure architecture. They transport small hydrophobic molecules such as steroids, bilins, retinoids, and lipids. Lipocalins can be found in gram negative bacteria, vertebrate cells, and invertebrate cells, and in plants. They are associated with many biological processes. ORM2 functions as transport protein in the blood stream. It is expressed by the liver and secreted in plasma. It seems that ORM2 function in modulating the activity of the immune system during the acute-phase reaction. It binds various hydrophobic ligands in the interior of its beta-barrel domain. It also binds synthetic drugs and influences their distribution and availability.
