Active Recombinant Mouse Igf2 Protein

• Cat.No.: Igf2-1224M
• Product Overview: Purified recombinant protein of Mouse insulin-like growth factor 2 (Igf2), transcript variant 2 (Ala25-Glu91) without tag was was expressed in E. coli.

Specification

• Species: Mouse
• Source: E.coli
• ProteinLength: 25-91 a.a.
• Description: This gene encodes a member of the insulin-like growth factor (IGF) family of proteins that promote growth and development during fetal and postnatal life. It is an imprinted gene that is expressed only from the paternal allele. The encoded protein undergoes proteolytic processing to generate a mature peptide. The transgenic overexpression of this gene in mice results in prenatal overgrowth, polyhydramnios, fetal and neonatal lethality, disproportionate organ overgrowth including tongue enlargement, and skeletal abnormalities. Mice lacking the encoded protein exhibit growth deficiency. Alternative splicing results in multiple transcript variants encoding different isoforms that may undergo similar processing to generate mature protein.
• Bio-activity: The ED50 is 10 - 30 ng/ml, corresponding to a specific activity of 0.3 - 1 x 10^5 units/mg, determined by the dose dependent stimulation of MCF-7 cell proliferation.
• Molecular Mass: 7.4 kDa
• Endotoxin: Less than 0.01 ng per µg protein as determined by the LAL method
• Purity: >98%, as determined by Coomassie stained SDS-PAGE.
