Opis

General description

Osteopontin is a single-chain polypeptide with a molecular weight of approximately 35 kDa. It is a glycoprotein first identified in osteoblasts. It is biosynthesized by a variety of tissue types including preosteoblasts, osteoblasts, osteocytes, extraosseous cells in the inner ear, brain, kidney, deciduum, placenta, odontoblasts, some bone marrow cells, hypertrophic chondrocytes, macrophages, smooth muscle, and endothelial cells. Osteopontin is overexpressed in a variety of cancers, including lung cancer, breast cancer, colorectal cancer, stomach cancer, ovarian cancer, melanoma and mesothelioma. It may contribute to kidney stone formation and both glomerulonephritis and tubulointerstitial nephritis and is also found in atheromatous plaques within arteries. Research has implicated osteopontin in excessive scar-forming and a gel has been developed to inhibit its effect.

~35 kDa

Immunogen

Synthetic peptide corresponding to amino acids 75-90 of human osteopontin (SwissProt Accession # P10451; PSKSNESHDHMDDM DD).

Application

Immunohistochemistry:
A previous lot of this antibodu was used at a 1:1500 dilution on paraffin-embedded tissue sections.

ELISA:
A previous lot of this antibody was used at a 1:1000 dilution.

Unpurified

Preparation Note

Stable for 1 year at -20°C in undiluted aliquots from date of receipt.

Handling Recommendations:
Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

Analysis Note

Control
POSITIVE CONTROL: Human urine (2-5 µg/mL normal concentration).

Routinely evaluated by Western Blot on RAW 264.7 lysates.

Western Blot Analysis: 1:500 dilution of this lot detected osteopontin on 10 μg of RAW 264.7 lysates.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
