描述
EphA8, also known as Hek3 and Eek, is a 120 kDa glycosylated member of the Eph family of transmembrane receptor tyrosine kinases. The A and B classes of Eph proteins are distinguished by Ephrin ligand binding preference but have a common structural organization. Eph-Ephrin interactions are widely involved in the regulation of cell migration, tissue morphogenesis, and cancer progression. Receptor tyrosine kinase which binds promiscuously GPI-anchored ephrin-A family ligands residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. The GPI-anchored ephrin-A EFNA2, EFNA3, and EFNA5 are able to activate EPHA8 through phosphorylation. With EFNA5 may regulate integrin-mediated cell adhesion and migration on fibronectin substrate but also neurite outgrowth. During development of the nervous system plays also a role in axon guidance. Downstream effectors of the EPHA8 signaling pathway include FYN which promotes cell adhesion upon activation by EPHA8 and the MAP kinases in the stimulation of neurite outgrowth.
Lyophilized from a 0.2 μm filtered solution of 20 mM Citrate, 6% Trehalose, 50 mM NaCl, 0.05% Tween 80, pH5.0.
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 100 μg/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。
