FAR1 Antibody, FITC conjugated

What is FAR1 and what role does it play in biological systems?

FAR1 (fatty acyl CoA reductase 1) is a protein with a calculated molecular weight of 59 kDa, comprising 515 amino acids. It functions primarily in fatty acid metabolism, catalyzing the reduction of fatty acyl-CoAs to fatty alcohols. FAR1 has been studied across multiple species including humans, mice, and rats. For research purposes, it's important to note that human FAR1 is encoded by gene ID 84188 with GenBank accession number BC017377 .

When designing experiments involving FAR1 antibodies, consider that this protein may demonstrate tissue-specific expression patterns and could be involved in multiple metabolic pathways, requiring careful experimental control selection.

What is the molecular basis of FITC conjugation to antibodies?

FITC (Fluorescein Isothiocyanate) conjugation occurs through the formation of a covalent bond between the isothiocyanate group of the fluorescein molecule and primary/secondary amine groups on the antibody, typically at lysine residues. The reaction is highly pH-dependent, with optimal conjugation occurring at alkaline pH (approximately 9.5) where amine groups are sufficiently deprotonated .

The conjugation process follows this reaction mechanism:

• Protein-NH₂ + FITC → Protein-NH-CS-FITC

• This thiourea linkage is stable and allows for fluorescent detection of the antibody

Maximal labeling is achieved under specific conditions:

• Reaction temperature: 25°C (room temperature)

• pH: 9.5

• Initial protein concentration: 25 mg/ml

• Reaction time: 30-60 minutes

What are the recommended storage conditions for FITC-conjugated FAR1 antibodies?

For maintaining optimal activity and fluorescence of FITC-conjugated FAR1 antibodies:

• Storage temperature: -20°C is recommended

• Buffer composition: PBS with 0.02% sodium azide and 50% glycerol at pH 7.3

• Stability period: Typically stable for one year after shipment under proper storage conditions

• Light protection: Critical to prevent photobleaching as continuous light exposure causes gradual fluorescence loss

• Aliquoting: May be unnecessary for -20°C storage for some preparations, but helps avoid repeated freeze-thaw cycles

What are the primary research applications for FITC-conjugated antibodies?

FITC-conjugated antibodies, including those targeting FAR1, are extensively utilized in:

• Immunofluorescence detection on fixed cells and tissues

• Flow cytometry for quantitative analysis of protein expression

• Fluorescence microscopy for localization studies

• Tissue cross-reactivity (TCR) studies for therapeutic antibody development

• Protein-protein interaction analyses

• Cellular uptake and trafficking investigations

• Transport and permeability studies across cell monolayers

• Microsequencing applications

• Drug release monitoring systems

The direct fluorescent labeling eliminates the need for secondary antibody incubation steps, reducing experimental complexity and potential sources of background.

How should I determine the appropriate dilution for FITC-conjugated FAR1 antibodies?

Determining optimal antibody dilution requires systematic titration:

• Starting point: For immunofluorescence on mammalian cells, begin with 1:500 dilution in PBS containing 10% fetal bovine serum (FBS)

• Titration approach: Test serial dilutions (e.g., 1:250, 1:500, 1:1000)

• Evaluation criteria:

  • Signal intensity at expected cellular locations

  • Signal-to-noise ratio

  • Background fluorescence levels

  • Staining pattern consistency with known FAR1 localization

• Application-specific adjustments: Different applications may require different optimal dilutions:

  • Immunohistochemistry: Often requires higher concentrations

  • Flow cytometry: May need optimization based on expression levels

• Controlling factors: Consider the degree of FITC labeling, as higher labeling indices increase sensitivity but may also increase non-specific binding

Record the fluorescein/protein (F/P) ratio of your antibody batch, as this affects optimal dilution requirements across experiments.

How does the degree of FITC conjugation affect binding affinity and specificity?

Research has established a clear inverse relationship between FITC-labeling extent and antibody binding performance:

Studies with FITC-labeled proteins have demonstrated that mono-conjugated versions (with a single FITC molecule attached) typically maintain binding properties most similar to the native protein. As the number of FITC molecules increases to di- and tri-conjugates, binding affinity progressively decreases .

The position of conjugation also influences activity. For instance, studies with insulin showed that B1-position conjugation preserved biological activity, while A1-position conjugation reduced activity by 10%, and multi-site conjugation (di- and tri-) decreased activity by up to 100% .

For FAR1 antibodies, selecting conjugates with appropriate labeling indices is crucial to balance detection sensitivity with maintained target specificity.

What methodologies can effectively separate different FITC-conjugated antibody populations?

To ensure experimental consistency, separating different FITC-conjugated antibody fractions is essential:

• Gradient DEAE Sephadex Chromatography:

  • Principle: Separation based on charge differences from varying FITC conjugation levels

  • Protocol:
    a) Equilibrate DEAE Sephadex column with starting buffer (typically low salt, pH 8.0)
    b) Apply FITC-antibody mixture to column
    c) Elute with increasing salt gradient (e.g., 0-0.5M NaCl)
    d) Collect fractions and analyze for F/P ratio

• Spectrophotometric Characterization:

  • Measure absorbance at 280nm (protein) and 495nm (FITC)

  • Calculate F/P ratio using established formulas:
    F/P = (A495 × dilution factor) / (ε495 × [protein concentration])
    where ε495 is the extinction coefficient of FITC

• Validation Methods:

  • SDS-PAGE analysis to confirm protein integrity

  • Binding assays to assess functional activity of each fraction

  • Fluorescence intensity measurements to confirm FITC incorporation

This separation process is critical for FAR1 antibodies to ensure consistent experimental performance across studies, especially when comparing results between different laboratories.

How can I assess whether FITC conjugation has altered epitope recognition?

To evaluate potential changes in epitope recognition after FITC conjugation of FAR1 antibodies:

• Comparative Binding Assays:

  • ELISA competitive binding: Compare IC50 values between conjugated and unconjugated antibodies

  • Surface Plasmon Resonance: Measure on/off rates and KD values to quantify affinity changes

• Procedural Controls:

  • No primary antibody control: To assess non-specific binding of detection systems

  • Concentration-matched controls: Using same protein concentration across different antibodies

  • F/P ratio standardization: Document and standardize fluorescein/protein ratio

• Application-Specific Controls:

  • For flow cytometry: Compensation controls, viability dyes

  • For microscopy: Counterstains to assess morphology

  • For tissue staining: Adjacent section controls

These controls should be systematically incorporated into experimental designs to ensure robust and interpretable results when using FITC-conjugated FAR1 antibodies.

How can the fluorescein/protein (F/P) ratio be optimized for maximum sensitivity and specificity?

Optimizing the F/P ratio requires a systematic approach to balance detection sensitivity with binding specificity:

• Conjugation Reaction Optimization:

  Parameter	Recommended Value	Effect on F/P Ratio
  Antibody purity	DEAE Sephadex purified	Higher purity enables more consistent conjugation
  FITC quality	High purity (>95%)	Reduces inactive FITC molecules
  Reaction pH	9.5	Maximizes reactive amine groups
  Temperature	25°C (room temperature)	Balances reaction rate with protein stability
  Protein concentration	25 mg/ml	Optimizes FITC-protein interaction
  Reaction time	30-60 minutes	Controls degree of labeling
  FITC:protein molar ratio	10:1 to 30:1	Primary determinant of final F/P ratio

• F/P Ratio Determination Methods:

  • Spectrophotometric calculation: Measure A280 and A495

  • F/P ratio = [A495 × Dilution factor × MW of protein] ÷ [ε495 × protein concentration (mg/ml)]

  • For IgG antibodies, typical calculation: F/P ratio = (A495 × 0.30) ÷ A280 - (0.35 × A495)

• Performance Characteristics by F/P Ratio:

  F/P Ratio	Sensitivity	Specificity	Recommended Applications
  1-2	Lower	Highest	Quantitative analysis, critical specificity applications
  3-5	Moderate	Good	Standard immunofluorescence, flow cytometry
  6-8	High	Moderate	Detecting low-abundance proteins
  >8	Highest	Poor	Not recommended - non-specific binding issues

• Application-Specific Optimization:

  • For FAR1 detection in fixed cells: Target F/P ratio of 3-5

  • For flow cytometry: F/P ratio of 2-4 offers best signal-to-noise

  • For detecting low-abundance proteins: Higher F/P ratios with additional blocking steps

The research indicates that for most applications using FAR1 antibodies, an F/P ratio of 3-5 provides optimal balance between sensitivity and specificity.
