分子别名（Synonym）:CDF,DIA,HILDA,Leukemia Inhibitory Factor,MLPLI
 

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 LIF comprises 191 amino acids and has a predicted molecular mass of 21.2 kDa. The apparent molecular mass of the protein is approximately 35-42 kDa in SDS-PAGE under reducing conditions.
 

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

生物活性(Activity)：Measured by its ability to inhibit the proliferation of M1 mouse myeloid leukemia cells.
 

表达区间（Protein Construction）：A DNA sequence encoding the human LIF (P15018) (Ser2-Phe202) with a C-terminal polyhistidine tag was expressed.
 

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.
