Technical Data
C7905-50
CPI-17 (PKC Potentiated Inhibitor Protein-17)
Description:
PKC Potentiated Inhibitor Protein-17 (CPI-17) is a 17kD protein. Expressed in smooth muscles and neuronal cells, CPI-17 is a myosin phosphatase inhibitor protein. Phosphorylation of CPI-17 at Thr38 enhances its inhibitory effect by 100 fold. Once phosphorylated, CPI-17 inhibits PP1c and MLCP holoenzyme activity.

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

Recommended Dilutions:
Western Blot: 0.2-1ug/ml. Detects CPI-17 in L6 lysates. L6 lystate was resolved by electrophoresis, transferred to nitrocellulose and probed with C7905-50. Proteins were visualized using an IgG (HRP) goat anti-rabbit secondary antibody and a chemiluminescence detection system.
Optimal dilutions to be determined by the researcher.

Recommended Secondary Antibodies:
I1904-39: IgG, X-Adsorbed (HRP) Pab Gt x Rb
I1904-40A: IgG, H&L, X-Adsorbed (HRP) Pab Gt x Rb
I1904-46Q: IgG, H&L (HRP) Pab Gt x Rb

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