Independent Validation (WB)

Validation #029752 (Western Blotting)

by: Alamo Laboratories Inc

No.: #029752

Date: 07/03/2014

Lot Number: 120918

Method validated: Western Blotting

Positive Control: Hela cells

Negative Control: c6/36 cells (non-reactive species)

Notes: A single major band was observed in the positive control at the correct molecular weight. Several additional faint bands appeared in both the positive and negative controls, but they did not indicate significant non-specific interaction.

Full Methods

Primary Antibody:

• Antigen: SMAD, Mothers Against DPP Homolog 1 (SMAD1) (1:200 dilution)
• Catalog number: ABIN732158
• Lot number: 120918

Secondary Antibody:

• Antibody: Goat Anti-Rabbit IgG (H + L)-HRP Conjugate (1:20,000 dilution)
• Lot number: L170-6515

Full Protocol:

• 1. Total protein extracts were boiled in 1X SDS Sample Buffer containing 1% SDS and 1.25% β-mercaptoethanol at 95°C for 5 min prior to loading.
• 2. 58 μg of boiled extracts were loaded and resolved on 8-16% SDS-polyacrylamide gel.
• 3. The Thermo Scientific - Spectra Multicolor Broad Range (Cat # 26634) were used as molecular mass markers.
• 4. Proteins were then transferred onto PVDF membrane by wet transfer and protein transfer was confirmed with Ponceau-S staining.
• 5. The PVDF membrane was incubated with 25 mL of blocking buffer [Tris Buffered Saline, pH 7.4 plus 0.1% TW20 (TBST)] containing 5% (W/V) BSA at room temperature for 1 h.
• 6. The membrane was rinsed with TBST once.
• 7. The membrane was immersed with the protein side up in the primary antibody solution (anti-SMAD1; 1:200) in TBST containing 5% (W/V) BSA and incubated for 16 h at 4°C.
• 8. The membrane was rinsed in TBST thrice for 5 min each.
• 9. The membrane was incubated in the HRP-conjugated secondary antibody solution (Goat anti-rabbit IgG-HRP; 1:20,000) in TBST containing 5% (W/V) BSA and incubated for 1 h at room temperature (~26°C) with gentle agitation.
• 10. The membrane was rinsed in TBST thrice for 5 min each.
• 11. The membrane was rinsed in TBS twice for 30 s each.
• 12. Signals were detected with ECL-2 Substrate. The blot was scanned for 300 s.
• 13. The membrane was rinsed three times TBST.
• 14. Incubated in Acidic Glycine Stripping Buffer at room temperature with gentle agitation for 3 times, 10 min each.
• 15. The membrane was washed in TBST 2 times for 10 min each.
• 16. Repeated Steps 5-12 with the loading control antibody (anti-Actin; 1:6,000) and its matching secondary antibody (Goat anti-rabbit IgG-HRP; 1:20,000).

Target Details for Smad1/5

Target: Smad1/5 (SMAD1/5) (Smad1/5 Protein (SMAD1/5))

Alternative Name: Smad1 + Smad5

Background:

Synonyms: Mothers against decapentaplegic homolog 5, SMAD5, Mothers against decapentaplegic homolog 1, SMAD1

Background: Transcriptional modulator activated by BMP (bone morphogenetic proteins) type 1 receptor kinase. SMAD5 is a receptor-regulated SMAD (R-SMAD). Transcriptional modulator activated by BMP (bone morphogenetic proteins) type 1 receptor kinase. SMAD1 is a receptor-regulated SMAD (R-SMAD). SMAD1/OAZ1/PSMB4 complex mediates the degradation of the CREBBP/EP300 repressor SNIP1. May act synergistically with SMAD4 and YY1 in bone morphogenetic protein (BMP)-mediated cardiac-specific gene expression.
