IGFBP-2 Protein, Rhesus Macaque (HEK293, His)

IGFBP‐2 is a member of a family of six insulin‐like growth factor (IGF) binding proteins. IGFBP-2 is the second most abundant IGFBP in the circulation and binds IGF-II with higher affinity than IGF-I. IGFBP-2 has been implicated in the regulation of IGF activity in most tissues and organs. IGFBP-2 Protein, Rhesus Macaque (HEK293, His) is the recombinant Rhesus Macaque-derived IGFBP-2 protein, expressed by HEK293 , with C-His labeled tag. The total length of IGFBP-2 Protein, Rhesus Macaque (HEK293, His) is 289 a.a., with molecular weight of ~33 KDa.

IGFBP‐2 is a member of a family of six insulin‐like growth factor (IGF) binding proteins. IGFBP-2 is the second most abundant IGFBP in the circulation and binds IGF-II with higher affinity than IGF-I. IGFBP-2 has been implicated in the regulation of IGF activity in most tissues and organs. IGFBP‐2 is involved in regulation of insulin-like growth factor receptor signaling pathway^[1][2][3][4].

Measured by its ability to inhibit the biological activity of IGF-I on MCF-7 human breast cancer cells. The ED₅₀ for this effect is 0.03282 µg/mL in the presence of 14 ng/mL rh IGF-I, corresponding to a specific activity is 3.047×10⁴ units/mg.

Approximately 33 kDa.

Greater than 90% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
