<strong>Figure 5 Immunohistochemistry Validation of Smac in Mouse Spleen Tissue </strong><br> Immunohistochemical analysis of paraffin-embedded Mouse Spleen Tissue using anti-Smac antibody (2411) at 2 μg/ml. Tissue was fixed with formaldehyde and blocked with 10% serum for 1 h at RT; antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody overnight at 4°C. A goat anti-rabbit IgG H&L (HRP) at 1/250 was used as secondary. Counter stained with Hematoxylin.
<strong>Figure 6 KO Validation in Mouse Fibroblasts and Myoblasts (Ho et al., 2007)</strong><br>The indicated MEFs or MEMs were exposed to 2 μM STS for 4 h and analyzed by Western blot. Accumulation of Smac/Diablo in mitochondrion-depleted cytosol fractions fromSTS-treated Apaf-1 KO cells were detected by anti-smac antibodies. Smac expression was not detected in smac KO mice.
<strong>Figure 7 Immunohistochemistry Validation of Smac in Human gastric carcinoma (Kim et al., 2011) </strong><br> Smac was highly expressed in gastric mucosa of patients with gastric carcinoma.
<strong>Figure 8 Immunofluorescence Analysis of Smac in NB4-LR1 Cells (Saumet et al., 2005) </strong><br> NB4-LR1 cells were either treated with ATRA(1 μM) for 3 days without or with the T3C1 recombinant fragment (3 μM) or treated with staurosporine (STP; 5 μM ) for 3.5 hours. STP, but not ATRA or AYRA/T3C1 induced the release of smac.

Cells were lysed, and lysates were incubated with the indicated concentrations of 1 and immunoprecipitated with anti-Myc antibody (left panels). Samples were then immunoblotted with anti-Smac and anti-Myc antibodies. Whole-cell lysates are shown in the right panel.

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.

Isoforms:
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). 2411 can detect human, mouse and rat.

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.
