What are the validated applications for INTS10 Antibody, FITC conjugated?

While specific applications for FITC-conjugated INTS10 antibodies have limited documentation in the provided search results, similar polyclonal INTS10 antibodies have been validated for several applications. Based on the antibody's characteristics and general principles of FITC-conjugated antibodies, the following applications are suitable:

• Immunofluorescence (IF): The FITC conjugation makes this antibody directly applicable for immunofluorescence studies without secondary antibody requirements. Recommended dilutions typically range from 1:50 to 1:200, though optimal concentrations should be determined empirically for each experiment .

• Flow Cytometry: FITC-conjugated antibodies are commonly used in flow cytometric analysis. For intracellular proteins like INTS10, proper cell permeabilization protocols are essential for antibody access.

How should an immunofluorescence protocol be optimized for INTS10 Antibody, FITC conjugated?

For optimal immunofluorescence results with INTS10 Antibody, FITC conjugated, researchers should follow this methodological approach:

• Sample Preparation:

  • Fix cells with 4% paraformaldehyde (10-15 minutes at room temperature)

  • Permeabilize with 0.1-0.5% Triton X-100 (5-10 minutes) to allow antibody access to nuclear targets

• Blocking:

  • Block with 1-5% BSA or 5-10% normal serum (from species different from the host of the antibody) in PBS for 30-60 minutes to reduce background

• Antibody Incubation:

  • Start with a dilution range of 1:50-1:200 as recommended

  • Incubate overnight at 4°C in a humidified chamber protected from light (critical for FITC preservation)

  • For co-localization studies, ensure other antibodies do not have spectral overlap with FITC (Ex/Em: 499/515 nm)

• Optimization Parameters:

  • Titrate antibody concentration (begin with manufacturer's recommendation and adjust based on signal-to-noise ratio)

  • Test different fixation methods if standard paraformaldehyde doesn't yield optimal results

  • Vary permeabilization conditions depending on subcellular localization (nuclear proteins like INTS10 may require stronger permeabilization)

  • Include appropriate positive controls (cell lines known to express INTS10) and negative controls (blocking peptide, isotype control)

• Counterstaining and Mounting:

  • Counterstain nuclei with DAPI (1 μg/ml for 5 minutes)

  • Mount with anti-fade mounting medium to prevent photobleaching of FITC

  • Store slides at 4°C protected from light

The optimal protocol should be established through systematic testing of these parameters, with particular attention to signal specificity in the nuclear compartment where INTS10 is predominantly localized.

    • Implement hierarchical gating strategy (viability → nuclear size → INTS10 intensity)

    • Add 5 μM DRAQ5 for simultaneous DNA content analysis

• Live Cell Adaptation Strategies:

  • Antibody Delivery Methods:

    • Fragment antibody to Fab using papain digestion to enhance nuclear penetration

    • Conjugate with cell-penetrating peptides (TAT, Penetratin)

    • Optimize electroporation parameters for direct cytoplasmic delivery

    • Package in cationic lipid nanoparticles for transient transfection

  • Microinjection Protocol:

    • Dilute antibody to 0.5-1.0 mg/mL in injection buffer

    • Add 0.5% glycerol to stabilize during microinjection

    • Co-inject with fluorescent dextran for injection control

    • Maintain cells at 37°C throughout injection process

• Multiplexed Detection Enhancements:

  • Sequential Staining Protocol:

    • Implement cyclic immunofluorescence with antibody stripping

    • Use 0.1M glycine (pH 2.5) or 6M urea for efficient stripping

    • Image FITC channels early in the sequence to minimize photobleaching

    • Register images using nuclear counterstain as fiducial marker

  • Tyramide Signal Amplification Integration:

    • Convert direct FITC detection to indirect tyramide-based amplification

    • Use anti-FITC HRP-conjugated secondary antibody

    • Develop with tyramide-488 for 5-10 minutes

    • Inactivate HRP with 1% sodium azide between cycles

These specialized protocol modifications extend the utility of INTS10 Antibody, FITC conjugated beyond standard applications, enabling researchers to address specialized research questions while maintaining specificity for the INTS10 target .
