TIMP3 Antibody, FITC conjugated

What is TIMP3 and why is it relevant for research?

TIMP3 (Tissue Inhibitor of Metalloproteinases 3) is a crucial protein that complexes with metalloproteinases and irreversibly inactivates them by binding to their catalytic zinc cofactor. It plays significant roles in tissue-specific acute responses to remodeling stimuli . TIMP3 is known to act on multiple matrix metalloproteinases including MMP-1, MMP-2, MMP-3, MMP-7, MMP-9, MMP-13, MMP-14, and MMP-15 . Research on TIMP3 is particularly relevant for understanding extracellular matrix regulation, cell signaling pathways, and neurodegenerative conditions. The protein is predominantly localized in the extracellular space and is enriched in placenta and adipose tissues . Its study provides insights into mechanisms of tissue remodeling, wound healing, and pathological conditions involving matrix degradation.

How should I select between polyclonal and monoclonal TIMP3 antibodies for my experiments?

Selection between polyclonal and monoclonal TIMP3 antibodies should be based on your specific experimental needs. The polyclonal TIMP3 antibodies, such as those FITC-conjugated variants documented in the search results, offer broad epitope recognition that can be advantageous for proteins with low expression levels . They typically recognize multiple epitopes on the TIMP3 protein, potentially providing stronger signals in applications like ELISA.

Monoclonal antibodies like the TIMP3 (D74B10) Rabbit mAb provide superior specificity to a single epitope, which is particularly valuable for distinguishing between closely related proteins or specific protein states . They also offer excellent lot-to-lot consistency. For quantitative studies requiring precise measurements, monoclonal antibodies may be preferable due to their consistent binding characteristics. Consider using polyclonal antibodies for initial detection and validation experiments, and monoclonal antibodies for studies requiring high specificity or standardized protocols.

What are the optimal storage conditions for maintaining TIMP3 antibody activity?

To maintain optimal activity of TIMP3 antibody, FITC conjugated, specific storage conditions must be followed. The antibody should be shipped at 4°C and upon receipt, aliquoted for long-term storage . For long-term preservation, store at -20°C or -80°C, with -80°C being preferable for extended periods beyond one year . The antibody is typically stable for one year after shipment when properly stored .

Repeated freeze-thaw cycles significantly reduce antibody activity, so creating single-use aliquots is essential . The storage buffer containing 0.03% Proclin 300, 50% Glycerol, 0.01M PBS, pH 7.4 helps maintain antibody stability . For antibodies in the 20μl size, note that they contain 0.1% BSA which provides additional stability . When handling, always keep antibodies on ice and minimize exposure to room temperature. Document the date of receipt, aliquoting, and freeze-thaw cycles to monitor potential degradation.

How should I optimize TIMP3 antibody dilutions for different experimental applications?

Optimization of TIMP3 antibody dilutions is critical for achieving reliable and reproducible results across different applications. Based on the research data, the following application-specific dilution ranges are recommended:

When optimizing dilutions, create a titration series spanning the recommended range and include appropriate positive and negative controls. For human samples, placenta tissue serves as an excellent positive control as TIMP3 is enriched in this tissue . For murine studies, brain tissue samples have demonstrated positive WB detection .

The observed molecular weight for TIMP3 is 20-30 kDa, with specific bands detected at approximately 20 and 25 kDa . Sample-dependent variations may occur, so optimization is necessary for each experimental system to obtain optimal results .

• Imaging parameters: Image using appropriate filter sets for FITC (excitation ~495nm, emission ~520nm). When conducting quantitative analysis, use identical acquisition parameters for all samples and include appropriate controls for autofluorescence.

• Signal amplification: If signal intensity is low, consider tyramide signal amplification (TSA) systems compatible with FITC, being careful to avoid overamplification which could lead to non-specific signal.

Remember that TIMP3 is primarily localized to the extracellular matrix , so expect an extracellular staining pattern rather than intracellular localization.

How can TIMP3 antibody be utilized in studying metalloproteinase regulation in tissue remodeling?

TIMP3 antibody, FITC conjugated provides a powerful tool for investigating metalloproteinase regulation in tissue remodeling through several advanced approaches:

• Co-localization studies: Combine TIMP3-FITC antibody with antibodies against specific MMPs (MMP-1, MMP-2, MMP-3, MMP-7, MMP-9, MMP-13, MMP-14, and MMP-15) to visualize and quantify interaction domains in tissues undergoing remodeling . This allows direct observation of the spatial relationship between TIMP3 and its target MMPs.

• Temporal regulation analysis: In wound healing or development models, use TIMP3-FITC antibody to track changes in TIMP3 expression over time alongside MMP activity assays. This combination reveals the dynamic balance between proteolytic activity and inhibition during tissue remodeling.

• ECM component correlation: Combine TIMP3 immunofluorescence with staining for ECM components (collagens, elastin, fibronectin) to evaluate how TIMP3 distribution correlates with matrix integrity in normal versus pathological remodeling scenarios.

• Intervention studies: In models where TIMP3 function is modulated (through overexpression, silencing, or pharmaceutical intervention), use TIMP3-FITC antibody to confirm target engagement and track resulting changes in tissue architecture through confocal or super-resolution microscopy.

• Flow cytometry applications: For studies involving cell suspensions from remodeling tissues, TIMP3-FITC antibody can be used in flow cytometry to quantify cell-associated TIMP3 and correlate with cell surface MMP expression.

The observed molecular weight range of 20-30 kDa with specific bands at 20 and 25 kDa suggests potential post-translational modifications or isoforms that should be accounted for in your quantitative proteomic analysis.

How should I interpret conflicting TIMP3 expression data between antibody-based and transcriptomic methods?

Discrepancies between TIMP3 protein expression (detected via antibodies) and mRNA levels (from transcriptomic methods) are common and require systematic interpretation:

• Post-transcriptional regulation assessment: TIMP3 is subject to extensive post-transcriptional regulation, including microRNA targeting. When discrepancies occur, evaluate the presence of regulatory microRNAs (e.g., miR-21, miR-221) known to modulate TIMP3 translation using RT-qPCR or small RNA sequencing.

• Protein stability analysis: TIMP3's extracellular localization and interaction with the ECM affects its stability and turnover rate . Compare protein half-life data with mRNA decay rates using pulse-chase experiments or translation inhibitors like cycloheximide to determine if differential stability explains the discrepancy.

• Technical validation workflow:

  • Validate antibody specificity using TIMP3 knockout/knockdown controls

  • Test multiple antibodies targeting different TIMP3 epitopes (polyclonal vs. monoclonal)

  • Use absolute quantification methods for both mRNA (digital droplet PCR) and protein (MS-based)

  • Verify sample integrity and extraction efficiency for both protein and RNA

• Experimental timing considerations: TIMP3 protein may accumulate in the ECM over time while mRNA expression is more dynamic. Implement time-course experiments to capture the temporal relationship between transcription and steady-state protein levels.

• Tissue heterogeneity factors: In complex tissues, discrepancies may reflect cellular heterogeneity. Consider single-cell RNA-seq paired with immunohistochemistry to resolve cell type-specific expression patterns that might be masked in bulk analyses.

When reporting conflicting data, present both protein and mRNA results with appropriate biological replicates and statistical analyses, avoiding overinterpretation of either dataset alone.

How can I address non-specific binding issues when using TIMP3 antibody, FITC conjugated?

When encountering non-specific binding with TIMP3 antibody, FITC conjugated, implement this systematic troubleshooting approach:

  • Commercial blocking solutions specifically designed for fluorescence applications

  • Combination blocking with both 2% BSA and 5% normal serum from the same species as the antibody host

• Adjust antibody concentration: If using concentrations in the higher range of recommendations (such as 1:200 for IHC), create a dilution series starting from 1:400 to 1:800 to identify the optimal signal-to-noise ratio .

• Implement additional washing steps:

  • Increase both the number and duration of washes (5-6 washes of 5-10 minutes each)

  • Include 0.05-0.1% Tween-20 in wash buffers to reduce hydrophobic non-specific interactions

  • Consider high-salt wash buffers (250-500mM NaCl) for one of the washing steps

• Sample-specific optimizations:

  • For tissues with high autofluorescence, pre-treat with sodium borohydride (0.1% for 10 minutes) or commercial autofluorescence quenching reagents

  • Implement Sudan Black B treatment (0.1-0.3% in 70% ethanol) specifically for tissues with high lipofuscin content

• Antibody pre-adsorption: If non-specific binding persists despite the above measures, consider pre-adsorbing the antibody with tissue powder prepared from a relevant negative control tissue.
