限制
仅限研究用
缓冲液
Lyophilized from a 0.2 μM filtered solution of 10 mM Sodium Citrate, pH 3.0
注意事项
Centrifuge the vial prior to opening. Reconstitute the protein in water to a concnetration of 0.1 ~ 1.0 mg/mL. Do not vertex. For extended storage, it is recommended to further dilute in a proper buffer containing a carrier protein such as 0.1 % BSA, and store in working aliquots at -20 °C or -80 °C
储存条件
-80 °C
储存方法
Store at -80°C. Thaw on ice, aliquot to individual single-use tubes, and then re-freeze immediately. Only 2-3 freeze thaw cycles are recommended.
This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer. The protein is expressed in a broad range of cell types, acts as a pleiotropic cytokine and is involved in the stress response program of cells after cellular injury. Increased protein levels are associated with disease states such as tissue hypoxia, inflammation, acute injury and oxidative stress.
