RASSF3 Antibody, FITC conjugated

What is RASSF3 and why is it important to study?

RASSF3 (Ras association domain-containing protein 3) is a member of the RASSF family of proteins that function as potential tumor suppressors and regulate various cellular processes. Unlike its more extensively studied family member RASSF1, which acts as a tumor suppressor and mediates death receptor-dependent apoptosis, RASSF3's specific functions are still being elucidated . Studying RASSF3 is important because it participates in signal transduction pathways and may be involved in tumor biology, cellular immunology, chromatin and nuclear signaling, and transcriptional regulation . Research on RASSF3 contributes to our understanding of Ras-mediated signaling networks and their implications in normal cellular function and disease states.

What are the key characteristics of RASSF3 Antibody, FITC conjugated?

RASSF3 Antibody, FITC conjugated is a polyclonal antibody typically derived from rabbit hosts that recognizes human RASSF3 protein . The antibody is conjugated to fluorescein isothiocyanate (FITC), a green fluorescent dye that enables direct visualization of the target protein in fluorescence-based applications. Key characteristics include:

• Specificity: Recognizes human RASSF3 (some variants also react with mouse, rat, and other species)

• Immunogen: Typically generated against recombinant human RASSF3 protein (2-109AA)

• Clonality: Polyclonal (derived from multiple B cell lineages)

• Isotype: IgG

• Purification: Protein G purified with >95% purity

• Storage conditions: Should be stored at -20°C or -80°C and repeated freeze-thaw cycles should be avoided

• Buffer composition: Typically supplied in buffers containing preservatives like Proclin 300, with glycerol and PBS

What applications is RASSF3 Antibody, FITC conjugated suitable for?

RASSF3 Antibody, FITC conjugated is primarily designed for applications that benefit from direct fluorescence detection without the need for secondary antibodies. Based on available data, this antibody has been validated for:

• ELISA (Enzyme-Linked Immunosorbent Assay): For quantitative detection of RASSF3 in solutions

• Immunofluorescence (IF): Recommended dilutions typically range from 1:50 to 1:200 for cellular localization studies

While not explicitly validated for all applications, FITC-conjugated antibodies are generally suitable for:

• Flow cytometry: For detecting RASSF3 expression in cell populations

• Immunocytochemistry (ICC): For visualizing RASSF3 localization within cultured cells

The FITC conjugation eliminates the need for secondary antibody incubation steps, simplifying experimental workflows and reducing background in multi-color immunostaining .

How does RASSF3 differ from other RASSF family members?

RASSF3 belongs to the RASSF (Ras Association Domain Family) protein family but differs from other members in several ways:

Unlike RASSF1, which has been well-characterized as a mediator of death receptor-dependent apoptosis and inhibitor of cell cycle progression , RASSF3's specific mechanisms remain under investigation. While RASSF1 has been shown to interact with CDC20 and regulate the anaphase-promoting complex , similar detailed interaction networks are still being explored for RASSF3.

How should I design a flow cytometry experiment using RASSF3 Antibody, FITC conjugated?

When designing a flow cytometry experiment with FITC-conjugated RASSF3 antibody, consider the following methodological approach:

• Panel Design Considerations:

  • FITC emits in the green spectrum (~519 nm), so avoid fluorophores with significant spectral overlap like PE or GFP in your panel

  • If multiple markers need to be analyzed simultaneously, select complementary fluorophores like APC, PE-Cy7, or BV421 for other targets

  • Include appropriate isotype controls conjugated to FITC to assess non-specific binding

• Sample Preparation Protocol:

  • For intracellular RASSF3 detection, use a fixation/permeabilization buffer compatible with FITC (avoid harsh detergents that might affect fluorescence)

  • Optimize cell concentration to 1×10^6 cells/100 μL for staining

  • Include a protein transport inhibitor if analyzing stimulation-dependent expression

• Staining Procedure:

  • Begin with a titration experiment using different antibody concentrations (typically 1:50 to 1:200 dilutions)

  • Incubate cells with antibody for 30-45 minutes at 4°C in the dark

  • Wash cells thoroughly to remove unbound antibody

  • Analyze promptly or fix in 1-2% paraformaldehyde if analysis must be delayed

• Analysis Strategy:

  • Set appropriate voltage for FITC channel using unstained and single-stained controls

  • Use fluorescence minus one (FMO) controls to set accurate gates

  • Consider using viability dyes in far-red channels to exclude dead cells, which can bind antibodies non-specifically

This methodological approach ensures reliable and reproducible detection of RASSF3 expression by flow cytometry while minimizing artifacts .

What are the optimal fixation and permeabilization conditions for RASSF3 immunofluorescence studies?

Optimizing fixation and permeabilization conditions is critical for successful RASSF3 immunofluorescence studies using FITC-conjugated antibodies:

Recommended Fixation Protocol:

• Culture cells on glass coverslips or chamber slides to appropriate confluence

• Wash cells gently with pre-warmed PBS (3×)

• Fix cells using one of the following methods:

  • 4% paraformaldehyde in PBS for 15 minutes at room temperature (preserves cell morphology)

  • Ice-cold methanol for 10 minutes at -20°C (better for certain epitopes and nuclear proteins)

• Wash fixed cells with PBS (3×)

Permeabilization Options:

• For paraformaldehyde-fixed cells:

  • 0.1-0.2% Triton X-100 in PBS for 10 minutes at room temperature

  • Alternative: 0.5% Saponin in PBS (gentler and reversible permeabilization)

• For methanol-fixed cells:

  • Additional permeabilization is typically unnecessary as methanol both fixes and permeabilizes

Blocking Recommendation:

• Block with 5% normal serum (from the species unrelated to the primary antibody host) in PBS with 0.1% Tween-20 for 1 hour at room temperature

• Include 1% BSA in blocking buffer to reduce non-specific binding

Antibody Incubation Protocol:

• Dilute FITC-conjugated RASSF3 antibody in blocking buffer (typical range 1:50-1:200)

• Incubate overnight at 4°C or 2 hours at room temperature in a humidified chamber protected from light

• Wash 3× with PBS-0.1% Tween-20

Nuclear Counterstaining:

• DAPI (blue) or propidium iodide (red) are recommended for nuclear visualization as they don't interfere with the FITC signal

This methodology maximizes signal-to-noise ratio while preserving the fluorescence properties of the FITC conjugate and the structural integrity of the target epitope.

How should RASSF3 Antibody, FITC conjugated be stored and handled to maintain optimal activity?

Proper storage and handling of FITC-conjugated RASSF3 antibody is essential to maintain its immunoreactivity and fluorescence properties:

Storage Recommendations:

• Aliquot the antibody upon receipt to minimize freeze-thaw cycles

• Protect from light exposure using amber tubes or by wrapping containers in aluminum foil

• Store reconstituted lyophilized antibodies at 2-4°C if they will be used within two weeks

Handling Best Practices:

• Thaw frozen aliquots rapidly at room temperature and keep on ice after thawing

• Centrifuge briefly before opening tubes to collect all liquid at the bottom

• Use sterile technique when handling antibody solutions

• Avoid repeated freeze-thaw cycles as this can significantly reduce activity

• FITC is sensitive to photobleaching; minimize exposure to light during handling and storage

Buffer Considerations:

• The antibody is typically formulated in a buffer containing:

  • 50% Glycerol to prevent freezing damage

  • PBS at pH 7.4 for stability

  • 0.03% Proclin 300 or other preservative to prevent microbial growth

• Avoid buffers containing high concentrations of primary amines that may interfere with FITC

Stability Information:

• Lyophilized antibody is stable at room temperature for at least one month

• Reconstituted antibody is stable for at least two weeks at 2-4°C

• Long-term stability (>1 year) is maintained at -20°C

Following these storage and handling guidelines will help maintain the antibody's performance and extend its useful life for research applications.
