RASAL2 Antibody, HRP conjugated

What is RASAL2 and what biological functions does it serve?

RASAL2 (RAS Protein Activator Like 2) is a RAS-GTPase-activating protein (RAS-GAP) that regulates RAS signaling pathways by promoting GTP hydrolysis of RAS proteins, effectively inactivating them. RASAL2 contains a characteristic GRD (GAP-related domain) and a coiled-coil structure at the C-terminus . This protein plays crucial roles in several cellular processes including:

• Regulation of RAS-mediated signal transduction

• Modulation of cell proliferation and metastasis pathways

• Involvement in chemotherapy resistance mechanisms, particularly in triple-negative breast cancer (TNBC)

• Alteration of RAS signaling homeostasis with implications for EGFR upregulation

RASAL2 can function as both a tumor suppressor and oncogene depending on the cellular context, making it a complex target for research.

What are the key technical specifications of commercially available RASAL2 Antibody (HRP conjugated)?

The RASAL2 Antibody conjugated with HRP is characterized by specific technical parameters essential for experimental planning:

These specifications provide a foundation for experimental design and troubleshooting.

How does RASAL2 contribute to cancer progression and therapeutic resistance?

RASAL2 demonstrates context-dependent roles in cancer progression:

In triple-negative breast cancer (TNBC), RASAL2 functions as a mediator of chemotherapy resistance. Mechanistically, RASAL2 GAP activity is required to confer kinase inhibitor sensitivity, as RASAL2-high TNBCs sustain basal RAS activity through suppression of negative feedback regulators SPRY1/2, together with EGFR upregulation . This altered signaling creates a vulnerability to combination therapies targeting MEK1/2 and EGFR pathways.

In hepatocellular carcinoma (HCC), upregulated RASAL2 promotes proliferation and metastasis, indicating an oncogenic role in this context . The expression of RASAL2 is higher in HCC tissues compared to normal liver tissues, suggesting its potential as a biomarker for this cancer type.

High RASAL2 levels predict clinical chemotherapy response and long-term outcomes in TNBC patients and are associated with activated oncogenic Yes-Associated Protein (YAP) through direct transcriptional regulation .

What are the optimal protocols for using RASAL2 Antibody (HRP conjugated) in Western Blotting experiments?

For optimal Western Blotting results with RASAL2 Antibody (HRP conjugated), researchers should follow this protocol:

• Sample Preparation:

  • Extract proteins from cells or tissues using standard lysis buffers containing protease inhibitors

  • Quantify protein concentration (Bradford/BCA assay)

  • Prepare samples containing 20-50 μg of total protein per lane

  • Denature samples in Laemmli buffer at 95°C for 5 minutes

• Gel Electrophoresis:

  • Use 8-10% SDS-PAGE gels due to RASAL2's high molecular weight (observed at 140-150 kDa)

  • Include molecular weight markers and positive controls (HeLa cell lysate is recommended)

• Transfer and Blocking:

  • Transfer proteins to PVDF membrane (recommended over nitrocellulose for high MW proteins)

  • Block membranes with 3-5% BSA in TBST for 1 hour at room temperature

• Antibody Incubation:

  • Dilute RASAL2 Antibody (HRP conjugated) at 1:1000 in blocking buffer (starting point, optimize as needed)

  • Incubate membrane overnight at 4°C with gentle rocking

  • Wash 3-5 times with TBST, 5 minutes each

• Detection:

  • Apply HRP substrate (ECL solution) directly to membrane

  • No secondary antibody is needed due to HRP conjugation

  • Expose to X-ray film or image using a digital imager

  • Expected band size: 140-150 kDa

Optimization tips: If background is high, increase washing time/stringency or further dilute primary antibody. If signal is weak, decrease antibody dilution or increase protein load.

How can researchers effectively validate RASAL2 antibody specificity to ensure experimental reliability?

Validating antibody specificity is crucial for generating reliable data. For RASAL2 Antibody (HRP conjugated), consider these validation approaches:

• Knockout/Knockdown Controls:
