Insulin-like growth factor-binding protein 7(IGFBP-7) is a secreted glycosylated protein that contains three protein domain modules. IGFBP7 contains an N-terminal IGFBP domain, followed by a Kazal-type serine proteinase inhibitor domain and a C-terminal immunoglobulin-like C2-type domain. Human and mouse IGFBP7 are highly homologous and share 94% aa sequence identity. It is expressed in many normal tissues and in cancer cells. It is abundantly expressed in high endothelial venules (HEVs) of blood vessels in the secondary lymphoid tissues. It binds IGF and insulin with very low affinity and has been shown to enhance the mitogenic actions of IGF and insulin. IGFBP7 also has IGF/insulin-independent activities. It interacts with heparan sulfate proteoglycans, type IV collagen, and specific chemokines. It supports weak cell adhesion, promotes cell spreading on type IV collagen, and stimulates the production of the potent vasodilator PGI2. It modulates tumor cell growth and has also been implicated in angiogenesis.
Lyophilized from a 0.2 μm filtered solution of PBS, 150mM NaCl, pH 7.4.
复溶
Always centrifuge tubes before opening.Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.如要长期保存，建议使用含载体蛋白(如 0.1%BSA、10%FBS、5%HSA)的溶液进一步稀释，如果是做无血清培养或者动物体内实验时，细胞因子中不能含有BSA、FBS 和 HAS，可以使用海藻糖作为载体，然后分装冻存于-20℃至-80℃。注:分装保存时建议使用低吸附的管子，并避免反复冻融；稀释分装浓度不低于 10μg/mL，分装体积不低于10μL。
分装后的蛋白在≤-20°C 下可稳定保存 3 个月。
