Technical Data
Osteoprotegerin (OPG, Osteoclastogenesis inhibitory factor, OCIF)
Osteoprotegerin (OPG, or osteoclastogenesis inhibitory factor) is a secretory glycoprotein belonging to TNF receptor superfamily. OPG consists of 401 amino acid with molecular weight of 55kD as a monomer and 110kD as a disulfide-linked dimer. Osteoprotegerin acts as a soluble factor in the regulation of bone mass and may be beneficial in the treatment of osteoporosis associated with increased osteoclast activity.

Suitable for use in ELISA, Western blotting.

Reconstitution: Add 0.1ml of deionized water and let the lyophilized pellet dissolve completely.
Slight turbidity may occur after reconstitution, which does not affect activity
of the antibody. In this case clarify the solution by centrifugation.

Storage and Stability: May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Freeze at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
