BM-40 SPARC Liquid. In 150 mM NaCl, 20 mM HEPES, pH 7.4. AVOID FREEZE/THAW CYCLES. Osteonectin purified from bovine bone. Acidic, Ca2+-binding glycoprotein found in a variety of embryonic and adult tissues containing actively proliferating and remodeling cells. One of the most abundant glycoproteins secreted by osteoblasts. Reported to play a role in the differentiation and maintenance of dermis. Involved in the regulation of bone mineralization. May also play a role in the disengagement of cells from the extracellular matrix. Purity: ≥95% by SDS-PAGE. pI 5.5. Ref.: Hunzelmann, N., et al. 1998. J. Invest. Dermatol. 110, 122.
