		Technical Data
029830	Insig1 (Insulin-induced Gene 1 Protein, INSIG-1, Immediate-early Protein CL-6, Insulin-induced Growth Response Protein CL-6, Cl-6)

Description:
Insulin-induced gene (InSig) localizes in the endoplasmic recticulum(ER) and is highly expressed in the liver and fibroblast cell lines. InSig1 and InSig2 play important roles in the regulation of cholesterol biosynthesis. Sterol induces InSig1 binding to the sterol-sensing domain of SREBP cleavage-activating protein (SCAP). Both InSig1 and Insig2 prevent the export of SCAP from the ER and thus, inhibit cholesterol synthesis by preventing the proteolytic cleavage of SREBPs by the Golgi enzymes.

Applications:
Suitable for use in Western Blot. Other applications not tested.

Recommended Dilution:
Western Blot: 0.5-4ug/ml
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
