Validation:
Independent Antibody Validation in Cell lines (Figure 2) shows similar Smac expression profile in human and mouse cell lines detected by two independent anti-Smac antibodies that recognize different epitopes, 2409 against human C-terminus domain and 2411 against murine C-terminus domain. Smac proteins are detected in the most tested cell lines at different expression levels by the two independent antibodies.
KO Validation (Figure 6) : Anti-Smac antibody specificity was further verified by Smac knockout mice. Smac signal smac KO mice was disrupted as compared to control.
Induced Expression Validation (Figure 6, 9) : Smac expression detected by anit-Smac antibodies was up-regulated by STS or rPVL treatment.
Overexpression Validation (Figure 10) : Smac overexpression was detected by anit-Smac antibodies on smac transfected HEK293T cells.
Isoform: Human Smac has 3 isoforms, including isoform 1 (239aa, 27.1kD) , isoform 2 (186aa, 21.2kD) , and isoform 3 (195aa, 22.3kD) . Mouse Smac has one isoform (237aa, 26.8kD) and Rat Smac also has one isoform (237aa, 26.9kD) . 2409 can detect human, mouse and rat Smac.

Alternate Name: Smac Antibody: Smac, AU040403, 0610041G12Rik, 1700006L01Rik, Smac, Diablo homolog, mitochondrial, Direct IAP-binding protein with low pI
User Note: Optimal dilutions for each application to be determined by the researcher.
BACKGROUND: Smac Antibody: The inhibitor of apoptosis proteins (IAPs) regulate programmed cell death by inhibiting members of the caspase family of enzymes. A novel mammalian protein that binds to IAPs and neutralizes the inhibitory effect of IAPs on caspases was recently identified and designated Smac/DIABLO. Smac/DIABLO is a mitochondrial protein that is released along with cytochrome c during apoptosis and activates cytochrome c/Apaf-1/capase-9 pathway. Analysis of the structural basis of Smac/DIABLO reveals that the N-terminal amino acids are required for binding of Smac/DIABLO to IAPs and activation of caspases. Smac/DIABLO is expressed in a variety of human and mouse tissues.
