Beta-klotho (KLB) is a coreceptor required for endocrine fibroblast growth factor (FGF) 15/19 and FGF21 signaling in the brain. Like Klotho, Klotho beta facilitates binding between FGF19 subfamily members and their receptors via formation of a ternary complex. The Klotho beta mediated interaction of human FGF19 with FGF Receptor 4 in the liver negatively regulates bile acid synthesis by controlling the secretion of two key bile acid synthase genes, cholesterol 7-alpha hydroxylase and sterol 12-alpha hydroxylase

Q86Z14 |
Source |
HEK293 Cells-derived Human Beta Klotho Protein, Met30-Thr983 with His tag at the C-terminal |
Molecular Weight |
Approximately 111.6 kDa. Due to glycosylation, the protein migrates to 115-130 kDa based on Tris-Bis PAGE result. |
Physical Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
Purity |
> 95% as determined by SDS-PAGE and HPLC |
Endotoxin |
< 1.0 EU per 1μg of the protein by the LAL method. |
Formulation |
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water. |
运输与保存方法
The products are shipped with ice pack and can be stored at -20℃ for 1 year.
2-7 days, 2 to 8 °C under sterile conditions after reconstitution.
3 months, -20 °C under sterile conditions after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles.
注意事项
1.For your safety and health, please wear lab coats and disposable gloves for operation.
