UNC5D Antibody, FITC conjugated

What is UNC5D and what biological functions does it serve?

UNC5D, also known as UNC5H4, is a netrin receptor belonging to the UNC5H family of proteins that act as transmembrane receptors for netrin-1 and play crucial roles in neural development. The protein functions as a receptor for netrin NTN4 that promotes neuronal cell survival and is involved in multiple neurological processes including axon guidance, cell migration, and cell-cell adhesion. UNC5D mediates axon repulsion of neuronal growth cones in the developing nervous system upon ligand binding and facilitates cell-cell adhesion via its interaction with FLRT3 on adjacent cells . Additionally, UNC5D serves as a dependence receptor that can induce apoptosis when not associated with its netrin ligand, suggesting a potential role in programmed cell death pathways .

What is the structural composition of UNC5D Antibody, FITC conjugated?

UNC5D Antibody, FITC conjugated is a fluorescein isothiocyanate-labeled polyclonal antibody developed in rabbits against specific epitopes of the human UNC5D protein. Typically, the antibody is generated using an immunogen consisting of recombinant Human Netrin receptor UNC5D protein (amino acids 90-212) . The antibody consists of immunoglobulin G (IgG) molecules conjugated with FITC fluorophores, allowing for fluorescent detection in various applications. The formulation generally includes preservatives such as 0.03% Proclin 300 and stabilizers like 50% glycerol in a 0.01M PBS buffer at pH 7.4 . This specific labeling enables direct visualization of UNC5D proteins in fluorescence-based detection methods without requiring secondary antibodies.

How does UNC5D function differ from other UNC5 family receptors?

UNC5D functions similarly to other UNC5 family members (UNC5A, UNC5B, UNC5C) as a netrin receptor, but exhibits distinct characteristics. While all UNC5 family proteins act as transmembrane receptors for netrin-1 and participate in axon guidance and neural cell migration, UNC5D has specific interactions with netrin NTN4 . UNC5D contains a death domain that, when cleaved by caspase, can produce an intracellular fragment capable of inducing apoptosis - a function that is inhibited by netrin binding . Unlike UNC5B (also known as UNC5H2 or p53RDL1), which has established links to p53-dependent pathways , UNC5D has a more specialized role in cell-cell adhesion through its interaction with FLRT3 . Additionally, UNC5D exists in two isoforms due to alternative splicing events , potentially contributing to functional diversity not observed in other family members.

What is the recommended methodology for immunofluorescence staining using UNC5D Antibody, FITC conjugated?

For optimal immunofluorescence staining using UNC5D Antibody, FITC conjugated, follow this methodological approach:

• Sample Preparation: Fix cells or tissue sections using 4% paraformaldehyde for 15-20 minutes at room temperature. For tissue sections, perform antigen retrieval if necessary.

• Permeabilization: Treat samples with 0.1-0.3% Triton X-100 in PBS for 5-10 minutes to allow antibody access to intracellular targets.

• Blocking: Incubate samples with 5-10% normal serum (from a species different from the antibody host) in PBS with 0.1% Tween-20 for 1 hour at room temperature to minimize non-specific binding.

• Primary Antibody Incubation: Dilute the UNC5D Antibody, FITC conjugated in blocking buffer at an optimized concentration (starting dilution 1:50-1:200 based on similar antibodies ). Incubate overnight at 4°C in a humidified chamber protected from light.

• Washing: Wash samples thoroughly with PBS containing 0.1% Tween-20 (3-5 times, 5 minutes each).

• Nuclear Counterstaining: Apply DAPI (1:1000 dilution) for 5-10 minutes to visualize nuclei.

• Mounting: Mount samples using an anti-fade mounting medium.

• Imaging: Visualize using a fluorescence microscope with appropriate filters for FITC (excitation ~495nm, emission ~520nm).

This protocol should be optimized for specific experimental conditions, including cell types, tissue characteristics, and target expression levels.

How does the performance of FITC-conjugated UNC5D antibody compare with non-conjugated variants in different applications?

For ELISA applications, both conjugated and non-conjugated antibodies demonstrate comparable specificity, though working dilutions differ (1:500-1:20000 for non-conjugated versus potentially different optimal dilutions for FITC-conjugated versions). In Western blotting, non-conjugated UNC5D antibodies have proven effective at dilutions of 1:500-1:2000 , while FITC-conjugated variants may require optimization if adapted for this application.

For immunohistochemistry and immunofluorescence applications, the directly-labeled FITC antibody provides immediate visualization capability, though with potentially less signal amplification than detection systems using enzyme-conjugated secondary antibodies or tyramide signal amplification methods.

What are the critical factors for specificity validation when using UNC5D Antibody, FITC conjugated?

Ensuring the specificity of UNC5D Antibody, FITC conjugated requires a multi-faceted validation approach:

• Positive and Negative Controls: Include tissues or cell lines with known high expression of UNC5D (positive control) and those with minimal or no expression (negative control). Neural tissues are appropriate positive controls given UNC5D's role in neuronal development .

• Blocking Peptide Competition: Perform parallel experiments where the antibody is pre-incubated with the immunizing peptide (amino acids 90-212 of human UNC5D ). Disappearance of signal in these conditions confirms specific binding.

• Knockdown/Knockout Validation: Compare staining patterns in wild-type samples versus UNC5D knockdown or knockout models. Significant reduction in signal intensity in the latter validates antibody specificity.

• Cross-reactivity Testing: Evaluate potential cross-reactivity with other UNC5 family members (UNC5A, UNC5B, UNC5C) through expression systems or tissues with differential expression patterns of these proteins.

• Western Blot Correlation: Confirm that the molecular weight of detected bands (~106 kDa for UNC5D ) corresponds to the expected size of the target protein.

• Multi-antibody Concordance: Compare staining patterns with alternative UNC5D antibodies targeting different epitopes to confirm consistent localization patterns.

• Signal-to-noise Ratio Assessment: Optimize antibody concentration to maximize specific signal while minimizing background fluorescence, particularly important for FITC-conjugated antibodies which may exhibit some autofluorescence in certain tissues.

What is the optimal protocol for detecting UNC5D in tissues with varying expression levels?

For detecting UNC5D in tissues with varying expression levels, a tiered approach is recommended:

For High-expressing Tissues:

• Use standard fixation with 4% paraformaldehyde for 15-20 minutes.

• Perform minimal antigen retrieval (if necessary) using citrate buffer (pH 6.0) for 10 minutes.

• Apply UNC5D Antibody, FITC conjugated at a higher dilution (1:200-1:500) to prevent signal saturation.

• Use shorter incubation times (4-6 hours at room temperature or overnight at 4°C).

• Image at lower exposure settings to avoid oversaturation.

For Medium-expressing Tissues:

• Fix with 4% paraformaldehyde for 20 minutes.

• Perform moderate antigen retrieval using citrate buffer (pH 6.0) for 15 minutes.

• Apply antibody at moderate dilution (1:100-1:200).

• Incubate overnight at 4°C.

• Use standard exposure settings for imaging.

For Low-expressing Tissues:

• Fix with 4% paraformaldehyde for 15 minutes (over-fixation can mask epitopes).

• Perform extensive antigen retrieval using Tris-EDTA buffer (pH 9.0) for 20 minutes.

• Apply antibody at lower dilution (1:50-1:100).

• Extend incubation time to 36-48 hours at 4°C.

• Consider signal amplification using anti-FITC antibodies conjugated to brighter fluorophores.

• Use longer exposure times during imaging.

For all protocols, include appropriate positive control tissues with known UNC5D expression patterns and carefully optimize each step for the specific tissue type being examined.

How should researchers design experiments to study UNC5D's role in apoptosis versus axon guidance?

To effectively investigate UNC5D's dual roles in apoptosis and axon guidance, researchers should design parallel experimental approaches:

For Apoptosis Studies:

• Cell Systems: Use neuronal cell lines or primary neurons with manipulated UNC5D expression (overexpression, knockdown, or knockout).
