Active Recombinant Human IGF1R protein, His-tagged

• Cat.No.: IGF1R-180H
• Product Overview: Recombinant Human IGF1R (Met1-Asn932) protein was fused to His-tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Species: Human
• Source: HEK293
• Tag: His
• ProteinLength: Met1-Asn932
• Form: Lyophilized from sterile PBS, pH 7.4
• Bio-activity: 1.Measured by its ability to bind IGF1 Protein, Human, Recombinant in functional ELISA.
  2.Captured IGF1R on NTA Chip can bind IGF1 with an affinity constant of 0.1317 µM as determined in a SPR assay (Biacore T200).
• Molecular Mass: The calculated molecular masses for α subunit, β subunit and the single chain of the receptor are approximately 81 kDa, 23 kDa and 104 kDa, respectively. As a result of glycosylation, the recombinant single chain, α subunit and β subunit have apparent molecular masses of approximately 150 kDa, 120 kDa and 48 kDa, respectively in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 90 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
