Active Recombinant Human INSR Protein, His & GST-tagged

Specification :
| Source : Baculovirus-Insect Cells | Species : Human | Tag : His & GST | Predicted N Terminal : Met | Form : Supplied as sterile 50mM Tris, 100mM NaCl, pH 7.4, 20% gly, 0.3mM DTT. | Bio-activity : The specific activity was determined to be 45 nmol/min/mg using Poly(Ala,Glu,Lys,Tyr)6:2:5:1 as substrate. | Molecular Mass : The recombinant human INSR (989-1382)/GST chimera consists of 631 amino acids and has a calculated molecular mass of 72.3 KDa. It migrates as an approximately 70 KDa band in SDS-PAGE under reducing conditions. | Endotoxin : | Purity : >92 % as determined by SDS-PAGE. | Stability : Samples are stable for up to twelve months from date of receipt at -70ºC. | Storage : Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
