Technical Data
Maspin (Serpin peptidase inhibitor, clade B (ovalbumin), member 5, Peptidase inhibitor 5, PI5, PI-5, Serpin B5)
Serine (or cysteine) proteinase inhibitor clade B (ovalbumin) member 5, also known as Maspin, is a tumor suppressor protein of serine proteinase inhibitor family. It plays an essential role in embryonic development through critical roles in cell adhesion. Also, it is present in normal breast and prostatic epithelial cells but downregulated in the respective carcinomas.

Suitable for use in Immunofluorescence, ELISA and Western Blot. Other applications not tested.

Recommended Dilutions:
Immunofluorescence: 1:500 detects Maspin in human HeLa cells
Western Blot: 1:1000-1:2000. Cell lysates of HeLa cells (20ug) were resolved by SDS-PAGE, transferred to NC membrane and probed with M21412-50F (1:1000). Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP* and an ECL detection system.
Optimal dilutions to be determined by researcher.

*Recommended Secondary Antibodies:
I1904-06C: IgG, H&L (HRP) (X-Adsorbed) Pab Gt xMo
I1904-06H: IgG, H&L (HRP) (X-Adsorbed) Pab Gt xMo
