Breast cancer estrogen-inducible protein /Trefoil factor 1
N-terminal 6x histidine tag
His-tag affinity purification by immobilized metal ion affinity chromatography (IMAC)
Purity determined by:
SDS-PAGE under reducing conditions and visualized by Coomassie blue staining
Molecular Weight (kDa):
Lyophilized from a 0.2 µ,m filtered solution in 100 mM NaH2PO4, 10 mM Tris-HCl, 100 mM imidazole, 1% sucrose solution(pH 8.0) with the protein concentration of 781 µ,g/ml
Briefly spin the vial and bring the contents to the bottom prior to opening. It is recommended to reconstitute at 0.5 - 1.0 mg/mL with sterile deionized water or 1x PBS.
Stability & Storage
Upon arrival, the lyophilized protein may be stored for 2 weeks at 4°C. For long term storage, it is recommended to store desiccated below -20°C in a manual defrost freezer. Following reconstitution, the protein may be stored for 2 weeks under sterile conditions at -20°C. For long term storage, it is recommended to make appropriate aliquots and store at -80°C. Avoid repeated freeze-thaw cycles.
