OPN ELISA Kit (Mouse) (OKBB00238)

OPN

Osteopontin (OPN) also called urinary stone protein, secreted phosphoprotein 1 (SPP1), bone sialoprotein, and early T lymphocyte activation 1 (ETA1). Osteopontin is a phosphorylated glycoprotein secreted to the mineralizing extracellular matrix by osteoblasts during bone development. It is believed to facilitate the attachment of osteoblasts and osteoclasts to the extracellular matrix, allowing them to perform their respective functions during osteogenesis.1 Osteopontin is presumably involved in stone formation as stone matrix.2 The deduced protein sequence reveals a 317-amino acid protein (34, 982 Da) containing a 16-amino acid hydrophobic signal sequence and a 33, 352-Da protein destines to undergo extensive post-translational modifications before being secreted from the cell. The gene is located on human chromosome 4.3 The standard product used in this kit is recombinant mouse OPN, consisting of 284 amino acid sequence with the molecular mass of 31.5KDa. As a result of glycosylation, the molecular mass is 65KDa.

No detectable cross-reactivity with any other cytokine.
