Packaging, Storage & Formulations

Store at 4C short term. Aliquot and store at -20C long term. Avoid freeze-thaw cycles.
Reconstitution Instructions
Centrifuge prior to opening. Reconstitute with PBS to a final concentration of 0.1 mg/ml. Further dilutions should be made in appropriately buffered solutions.


This lyophilized preparation is stable at 2-8 degrees C, but should be kept at -20 degrees C for long term storage, preferably desiccated. Upon reconstitution, the preparation is most stable at -20 to -80 degrees C, and can be stored for one week at 2-8 degrees C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 degrees C to -80 degrees C. Avoid repeated freeze/thaw cycles.

Osteopontin (OPN), also known as SPP1, Eta-1, or BSP, is a highly acidic, 45-75 kDa secreted molecule in the SIBLING family of matricellular proteins. It can be variably modified with O- and N-glycosylation, sulfation, phosphorylation, and transglutamination. OPN binds several integrins and can bind additional integrins after it is proteolytically cleaved. OPN is prominently expressed in mineralized tissues. It inhibits bone mineralization and kidney stone formation and promotes inflammation, cell adhesion, and cell migration. OPN expression is upregulated during inflammation, obesity, atherosclerosis, cancer, and tissue damage, and it contributes to the pathophysiology of these conditions.
