SRPX Antibody, Biotin conjugated

What is SRPX protein and why is it significant in research?

SRPX (Sushi repeat-containing protein SRPX) is a protein that may play important biological roles in phagocytosis during disk shedding, cell adhesion to cells other than the pigment epithelium, and signal transduction pathways . The significance of SRPX in research stems from its potential involvement in cellular processes that are fundamental to understanding both normal physiology and pathological conditions. Researchers often study SRPX in cell biology contexts to elucidate its functional roles in cellular communication and structural organization.

What are the key characteristics of SRPX Antibody, Biotin conjugated?

SRPX Antibody, Biotin conjugated (e.g., CSB-PA022689LD01HU) is a polyclonal antibody developed in rabbit hosts that specifically targets human SRPX protein. The antibody is generated using recombinant Human Sushi repeat-containing protein SRPX (amino acids 31-237) as the immunogen . The biotin conjugation enables signal amplification through high-affinity interaction with avidin or streptavidin molecules. This antibody typically has IgG isotype characteristics, is purified using Protein G chromatography (>95% purity), and is stored in a buffer containing preservative (0.03% Proclin 300), 50% glycerol, and 0.01M PBS at pH 7.4 .

How does biotin conjugation enhance antibody performance in immunoassays?

Biotin conjugation enhances antibody performance through several mechanisms:

• Signal amplification: Biotin forms a high-affinity, non-covalent bond with avidin/streptavidin, enabling multiple detection molecules to bind to a single antibody, thereby significantly amplifying the detection signal .

• Versatility in detection systems: Biotinylated antibodies can be detected using various streptavidin or avidin conjugates linked to fluorophores, enzymes, or other detection molecules, providing flexibility in experimental design .

• Sensitivity improvement: When biotin includes a spacer arm (like Biotin-SP), it extends the biotin moiety away from the antibody surface, making it more accessible to binding sites on streptavidin and thereby increasing sensitivity, especially with alkaline phosphatase-conjugated streptavidin .

• Application across multiple techniques: The biotin-streptavidin system enables consistent use across various techniques including ELISA, Western blotting, immunohistochemistry, immunocytochemistry, and flow cytometry .

What is the optimal protocol for using SRPX Antibody, Biotin conjugated in ELISA?

Optimal ELISA Protocol for SRPX Antibody, Biotin conjugated:

• Coating: Coat 96-well plate with capture antibody (anti-SRPX) at 1-2 μg/ml in carbonate buffer (pH 9.6) overnight at 4°C.

• Blocking: Block remaining protein-binding sites with 1-5% BSA or appropriate blocking solution for 1-2 hours at room temperature.

• Sample addition: Add samples and standards in dilution buffer (typically PBS with 0.05% Tween-20 and 1% BSA) for 1-2 hours at room temperature.

• Primary detection: Apply SRPX Antibody, Biotin conjugated at optimal dilution (typically 1:2000-1:10000 for ELISA applications) . Incubate for 1-2 hours at room temperature.

• Secondary detection: Add streptavidin-HRP or streptavidin conjugated to appropriate enzyme at recommended dilution. Incubate for 30-60 minutes.

• Substrate addition: Add appropriate substrate (TMB for HRP) and monitor color development.

• Stopping reaction: Add stop solution (e.g., 2N H₂SO₄ for TMB).

• Measurement: Read absorbance at appropriate wavelength (450nm for TMB).

Between each step, wash the plate 3-5 times with washing buffer (PBS with 0.05% Tween-20) to remove unbound reagents.

How should researchers optimize biotin-conjugated antibody concentration for signal amplification techniques?

Optimization Process for Biotin-Conjugated Antibody Concentration:

• Titration experiment: Perform a checkerboard titration with serial dilutions of the biotinylated antibody (typically ranging from 1:100 to 1:10,000) against various concentrations of target protein.

• Signal-to-noise assessment: For each dilution, calculate the signal-to-noise ratio by dividing specific signal by background signal. The optimal dilution typically provides the highest signal-to-noise ratio rather than the strongest absolute signal.

• Streptavidin conjugate optimization: Once the optimal antibody dilution is established, optimize the streptavidin conjugate concentration through a similar titration procedure.

• Incubation parameters: Test different incubation times (30 minutes to overnight) and temperatures (4°C, room temperature, 37°C) to determine conditions that maximize specific binding while minimizing background.

• Buffer composition adjustment: Modify buffer components (salt concentration, pH, blocking agents) to improve specificity and reduce non-specific binding.

• Positive and negative controls: Always include appropriate controls to validate results and ensure specificity of the detection system.

• Endogenous biotin blocking: When working with tissues or cells that contain endogenous biotin, incorporate a biotin blocking step to prevent false positive signals .

How can researchers address non-specific binding issues when using SRPX Antibody, Biotin conjugated?

Strategies to Minimize Non-Specific Binding:

• Optimize blocking conditions: Test different blocking agents (BSA, casein, normal serum, commercial blockers) at various concentrations (1-5%) and incubation times (1-3 hours) to identify the most effective combination for your specific sample type.

• Adjust antibody dilution: Increase the dilution of the SRPX Antibody, Biotin conjugated to reduce non-specific interactions, while maintaining sufficient specific binding.

• Modify wash protocols: Increase the number of washes (from 3 to 5-7) and/or the stringency of wash buffers (adding additional detergent or salt) to remove weakly bound antibodies.

• Pre-adsorption: Consider pre-adsorbing the antibody with proteins from the species of your sample to remove cross-reactive antibodies.

• Buffer optimization: Adjust buffer components by adding detergents (0.05-0.1% Tween-20), carrier proteins (0.1-1% BSA), or increasing salt concentration (150-500 mM NaCl) to reduce non-specific interactions.

• Control for endogenous biotin: Use commercial endogenous biotin blocking kits before applying biotinylated antibodies, particularly important for tissues rich in endogenous biotin (liver, kidney, brain) .

• Cross-reactivity testing: Verify antibody specificity using Western blot or immunoprecipitation to ensure it recognizes only the intended target.

• Secondary detection optimization: Use highly cross-adsorbed streptavidin conjugates to minimize non-specific binding to endogenous biotin-containing proteins.

What are the critical storage conditions for maintaining SRPX Antibody, Biotin conjugated activity over time?

Optimal Storage and Handling Conditions:

• Temperature: Store the antibody at -20°C or -80°C for long-term storage. Avoid repeated freeze-thaw cycles by creating small, single-use aliquots upon receipt .

• Buffer composition: The antibody is typically stored in a buffer containing 50% glycerol, 0.01M PBS (pH 7.4), and 0.03% Proclin 300 as a preservative . This composition helps maintain stability during freeze-thaw cycles.

• Aliquoting strategy: Divide the original antibody solution into small volumes (10-20 μl) sufficient for single experiments to prevent contamination and degradation from repeated handling.

• Working dilution stability: Diluted antibody solutions should be prepared fresh for each experiment. If storage is necessary, keep at 4°C for no more than 1 week.

• Light exposure: Minimize exposure to light, especially important for fluorophore-conjugated detection reagents used with biotinylated antibodies.

• Contamination prevention: Use sterile techniques when handling the antibody to prevent microbial contamination, which can degrade antibody activity and introduce experimental artifacts.

• Monitoring antibody performance: Periodically test antibody activity using positive controls to ensure continued functionality, especially for antibodies stored for extended periods.
