分子别名（Synonym）:EGF
 

种属（Species）：Rat
 

表达系统（Expressed Host）：E. coli
 

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

分子量（Molecule Mass）：The recombinant rat EGF consists of 54 amino acids and has a predicted molecular mass of 6.3 kDa. The apparent molecular mass of  the recombinant protein is approximately 6-9 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 in a cell proliferation assay using BALB/c 3T3 mouse fibroblasts.
 

表达区间（Protein Construction）：A DNA sequence encoding the rat EGF (NP_036974.1) (Asn974-Arg1026) was expressed and purified with an initial Met.
 

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.
