Background: Insulin-like growth factor I (also known as somatomedin C and somatomedin A) and insulin-like growth factor II (multiplication stimulating activity or MSA) belong to the family of insulin-like growth factors that are structurally homologous to proinsulin. Mature IGF-I and IGF-II share approximately 70% sequence identity. Both IGF-I and IGF-II are expressed in many tissues and cell types and may have autocrine, paracrine and endocrine functions. Mature IGF-I and IGF-II are highly conserved (100% identity between human, bovine and porcine proteins) and exhibit cross-species activity. IGF-II is a potent mitogenic growth factor. However, unlike IGF-I which has important postnatal roles, the growth-promoting function of IGF-II is limited to embryonic development.

Concentration:

Activity: Measure by its ability to induce MCF-7 cells proliferation.The ED₅₀ for this effect is <6 ng/mL.The specific activity of recombinant mouse IGF-II is > 1.5 x 10⁵ IU/mg.

Sequence: Ala 25-Glu 91

Purity: > 98 % as determined by reducing SDS-PAGE.

Formulation: Lyophilized from sterile PBS,pH 8.0.
Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.

Reconstitution: Please refer to the printed manual for detailed information.

Endotoxin: < 0.1 EU per μg of the protein as determined by the LAL method.

Calculated MW: 8.2 kDa
