分子别名（Synonym）:IGFBP4

种属（Species）：Cynomolgus

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 heterodimer of cynomolgus IGFBP4 comprises 248 amino acids and has a calculated molecular mass of 27.4 KDa. The apparent molecular mass of the protein is approximately 33-36 KDa respectively in SDS-PAGE.

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 biological activity of IGFII on MCF7 human breast adenocarcinoma cells (Karey, K.P. et al. (1988) Cancer Research 48:4083.).

表达区间（Protein Construction）：A DNA sequence encoding the cynomolgus IGFBP4 (Ser2-Glu258) was expressed with a polyhistidine tag 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.
