Target Background

Function
FEZF1, a transcription repressor, plays a crucial role in various biological processes. It is involved in axonal projection and proper termination of olfactory sensory neurons (OSN), contributing to the accurate formation of olfactory circuitry. FEZF1 also participates in the rostro-caudal patterning of the diencephalon and the development of the prethalamic region. Its expression in OSN is essential for cell-autonomous regulation of OSN axon projections. Furthermore, FEZF1 non-cell-autonomously regulates layer formation during olfactory bulb development and influences the differentiation of interneurons. FEZF1 is likely required for the correct rostral migration of interneuron progenitors.

Q&A

What is FEZF1 protein and what biological functions does it serve?

FEZF1 (Fez family zinc finger protein 1) is a zinc-finger transcription factor that plays crucial roles in neural development, particularly in olfactory sensory neuron identity and function. Research has demonstrated that FEZF1, together with its related protein FEZF2, regulates the identity of main olfactory epithelium (MOE) sensory neurons and is essential for proper olfactory development . The protein contains characteristic zinc-finger domains that facilitate DNA binding and subsequent transcriptional regulation.

FEZF1 functions in multiple developmental contexts:

  • Regulation of sensory neuron identity

  • Participation in olfactory system development

  • Involvement in neuronal differentiation pathways

  • Potential roles in cell proliferation and migration during development

On a molecular level, FEZF1 participates in transcriptional regulatory networks that determine cell fate and differentiation in the developing nervous system. Understanding these functions provides important context for researchers utilizing FEZF1 antibodies in developmental biology and neuroscience research .

What applications is the FEZF1 Antibody, Biotin conjugated suitable for?

The FEZF1 Antibody, Biotin conjugated is specifically designed for several research applications:

ApplicationSuitabilityRecommended DilutionNotes
ELISAHigh0.1-0.2 μg/mlPrimary detection method
Western BlottingGoodVariable by manufacturerCan detect human FEZF1
ImmunohistochemistryGoodFollow manufacturer recommendationsFor tissue localization
FACSPotentialPer protocol optimizationFor cell sorting applications

The antibody demonstrates reactivity with human FEZF1 samples, with predicted cross-reactivity to rat and other mammalian models. When selecting this antibody for research, consider that it targets the C-terminal region of FEZF1, which may affect epitope accessibility in certain experimental contexts .

For optimal results, researchers should validate the antibody in their specific experimental system before proceeding with full-scale experiments. The biotin conjugation makes this antibody particularly suitable for detection systems employing streptavidin-based amplification strategies .

How does biotin conjugation enhance detection sensitivity and experimental flexibility?

Biotin conjugation significantly enhances antibody utility through several mechanisms:

The biotin-streptavidin interaction forms one of the strongest non-covalent bonds in biological systems (Kd ≈ 10^-15 M), providing exceptional stability in experimental conditions. This property translates to several methodological advantages:

  • Amplified signal detection: The streptavidin molecule can bind multiple biotin molecules, creating signal amplification opportunities. A single biotinylated antibody can recruit multiple streptavidin-conjugated reporter molecules, enhancing detection sensitivity by 2-4 fold compared to direct conjugation methods .

  • Modular experimental design: Researchers can use the same biotinylated primary antibody with different streptavidin-conjugated detection molecules (fluorophores, enzymes, nanoparticles) without requiring multiple directly-conjugated antibodies.

  • Compatibility with toxin conjugation approaches: As demonstrated in antibody-drug conjugate development, biotinylated antibodies can be rapidly paired with biotinylated toxins via streptavidin bridges, enabling efficient screening of therapeutic combinations .

  • Reduced background: The specific biotin-streptavidin interaction generally produces lower non-specific binding compared to other secondary detection systems, particularly advantageous in complex tissue samples.

When working with FEZF1 Antibody, Biotin conjugated, this versatility allows researchers to select the most appropriate detection strategy for their specific experimental needs without requiring multiple specialized antibodies .

What are the optimal storage and handling conditions for maintaining FEZF1 Antibody, Biotin conjugated activity?

Proper storage and handling of FEZF1 Antibody, Biotin conjugated is essential to maintain its specificity and activity:

Storage recommendations:

  • Store aliquoted antibody at -20°C to prevent repeated freeze-thaw cycles

  • Avoid repeated freeze/thaw cycles; limit to 5 or fewer for maximum retention of activity

  • For working solutions, store at 4°C for up to one month in appropriate buffer containing preservatives

  • The antibody is typically supplied in a buffer containing 0.01 M PBS, pH 7.4, with 0.03% Proclin-300 and 50% glycerol

Handling considerations:

  • Always wear gloves when handling antibody solutions to prevent contamination

  • Centrifuge the vial briefly before opening to collect solution at the bottom

  • When preparing dilutions, use high-quality, nuclease-free buffers

  • For long-term storage beyond 12 months, consider storing at -80°C in small working aliquots

Activity preservation:

  • The biotin conjugate is sensitive to extreme pH; maintain solutions between pH 6.0-8.0

  • Avoid exposure to strong oxidizing agents that may damage the biotin moiety

  • Protect from prolonged light exposure, particularly when working with detection systems

  • Shield from microbial contamination by using sterile techniques and adding appropriate preservatives

Following these recommendations will help maintain antibody performance throughout the research project timeline and minimize batch-to-batch variations in experimental results .
