MAB195P Monoclonal Antibody to Human Osteopontin, N-terminal
Background Human Osteopontin (OPN) is a negatively charged, hydrophilic protein of 314 amino acids and is subject to significant post translational modifications (PTMs) including phosphorylation and glycosylation. Due to its acidic nature and PTMs, OPN runs anomalously by SDS-PAGE. Although its mass is 35kD, apparent molecular weights may range up to 75kD. In addition, OPN is subject to proteolytic modification into smaller molecular weight fragments.
Clone Determination 2E11
Immunogen Recombinant full-length human Osteopontin
Immunoglobulin Class IgG1 κ
Specificity Specific for the N-terminal fragment of full-length Osteopontin. Recognizes native human Osteopontin from purified breast milk and recombinant murine OPN expressed in E.coli.
Purification Protein A chromatography from ascites
Buffer 0.15M PBS
Applications ELISA, WB
Storage Store at -20C to -80C; avoid repeat freeze- thaw cycles
