Protocole

Anticorps primaire:

• Antigen: Breast Cancer 2, Early Onset (BRCA2)
• Catalog number: ABIN673434
• Lot number: 101020
• Antibody Dilution: 1:200

Anticorps secondaire:

• Antigen: Goat Anti-Rabbit IgG (H + L)-HRP Conjugate
• Lot number: L170-6515
• Antibody Dilution: 1:10,000

Full Protocol:

• 1. The cell extracts were heated at 95°C for 5 minutes in 1X SDS Sample Buffer containing 1% SDS and 1.25% β-mercaptoethanol.
• 2. 15 μl of heated culture-media 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 hour.
• 6. The membrane was rinsed with TBST once.
• 7. The membrane was immersed with the protein side up in the primary antibody solution in TBST containing 5% (W/V) BSA and incubated for 10 hours at 4°C.
• 8. The membrane was rinsed in TBST thrice for 5 minutes each.
• 9. The membrane was incubated in the HRP-conjugated secondary antibody solution in TBST containing 5% (W/V) BSA and incubated for 1 hour at room temperature (~26°C) with gentle agitation.
• 10. The membrane was rinsed thrice TBST thrice for 5 minutes each.
• 11. The membrane was rinsed in TBS twice for 30 seconds each.
• 12. Signals were detected with ECL-2 Substrate. The blot was scanned for 5 minutes.
• 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 minutes each.
• 15. The membrane was washed in TBST 2 times for 10 minutes each.
• 16. Repeated Steps 5-12 with the loading control antibody (for Anti-actin) and its matching secondary antibody.

Background: Involved in double-strand break repair and/or homologous recombination. Binds RAD51 and potentiates recombinational DNA repair by promoting assembly of RAD51 onto single-stranded DNA (ssDNA). Acts by targeting RAD51 to ssDNA over double-stranded DNA, enabling RAD51 to displace replication protein-A (RPA) from ssDNA and stabilizing RAD51-ssDNA filaments by blocking ATP hydrolysis. Part of a PALB2-scaffolded HR complex containing RAD51C and which is thought to play a role in DNA repair by HR. May participate in S phase checkpoint activation. Binds selectively to ssDNA, and to ssDNA in tailed duplexes and replication fork structures. May play a role in the extension step after strand invasion at replication-dependent DNA double-strand breaks, together with PALB2 is involved in both POLH localization at collapsed replication forks and DNA polymerization activity. In concert with NPM1, regulates centrosome duplication. Interacts with the TREX-2 complex (transcription and export complex 2) subunits PCID2 and DSS1, and is required to prevent R-loop-associated DNA damage and thus transcription-associated genomic instability. Silencing of BRCA2 promotes R-loop accumulation at actively transcribed genes in replicating and non-replicating cells, suggesting that BRCA2 mediates the control of R-loop associated genomic instability, independently of its known role in homologous recombination (PubMed:24896180).
