分子别名（Synonym）:ACTRIB,ACVRLK4,ALK4,SKR2

种属（Species）：Human

表达系统（Expressed Host）：HEK293 Cells

产品状态（Buffer）：Lyophilized from sterile PBS, pH 7.4

分子量（Molecule Mass）：The recombinant human ALK4/Fc is a disulfide-linked homodimer. The reduced monomer consists of 351 amino acids and has a predicted molecular mass of 39.6 kDa. In SDS-PAGE under reducing conditions, rhALK4/Fc monomer migrates as an approximately 46 kDa band due to glycosylation, with ~15% free Fc fragment.

内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.

生物活性(Activity)：Measured by its binding ability in a functional ELISA

表达区间（Protein Construction）：A DNA sequence encoding the human ACVR1B (NP_004293.1) extracellular domain (Ser 2-Glu 126) was fused with C-terminal His-tagged Fc region of human IgG1 at the C-terminus.

存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.

运输条件： In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
