TREH Antibody

What is TREH and why is it significant in research?

TREH (trehalase) is an enzyme responsible for hydrolyzing trehalose, a disaccharide that serves as an energy source and stress protectant in many organisms. Research with TREH antibodies enables studies of trehalose metabolism in various physiological and pathological conditions. The enzyme's distribution across tissues including cerebral cortex, duodenum, kidney, and testis makes it relevant to multiple research fields . Understanding TREH expression patterns provides insights into metabolic processes across diverse biological systems and potential disease mechanisms.

How are TREH antibodies validated for research use?

TREH antibodies undergo rigorous validation processes similar to other research antibodies. Validation typically includes immunohistochemical staining across multiple tissue types to confirm specificity and reproducibility. For example, TREH antibody HPA042045 shows similar protein distribution patterns across human cerebral cortex, duodenum, kidney, and testis when compared with independent antibody HPA039913, confirming specificity through concordant results . Proper validation should include positive and negative controls, cross-reactivity testing, and application-specific performance verification to ensure reliable experimental outcomes.

What sample types are compatible with TREH antibody studies?

TREH antibodies can be used with various sample types depending on the experimental goal:

• Fixed tissue sections for immunohistochemistry (IHC)

• Cell cultures for immunocytochemistry (ICC)

• Protein lysates for Western blotting (WB)

Each application may require specific sample preparation protocols. For tissue-based applications, proper fixation and antigen retrieval are crucial for optimal antibody binding and signal detection . Cell-based applications might require different permeabilization methods depending on the subcellular localization of TREH.

How should TREH antibody experiments be designed to ensure reproducibility?

Reproducibility in TREH antibody experiments requires careful consideration of several factors:

• Antibody selection: Choose antibodies with validation in your specific application and species of interest

• Proper controls: Include positive controls (tissues known to express TREH), negative controls (tissues without TREH expression), and technical controls (primary antibody omission)

• Standardized protocols: Maintain consistent antibody concentrations, incubation times, and detection methods

• Documentation: Record complete antibody information using Research Resource Identifiers (RRIDs) for citations

Experiments should be designed with attention to these factors to minimize variability. The Antibody Registry provides persistent identifiers (RRIDs) for antibodies, which are increasingly required by scientific journals to improve research reproducibility .

What are the key considerations when analyzing contradictory TREH antibody results?

When faced with contradictory results using TREH antibodies, researchers should systematically evaluate:

• Antibody specificity: Different antibodies targeting different epitopes of TREH may produce varying results

• Technical variations: Differences in tissue processing, antigen retrieval methods, or detection systems

• Biological variations: Expression differences between species, tissues, developmental stages, or disease states

• Lot-to-lot variation: Performance differences between antibody production batches

Researchers should perform thorough controls and consider using multiple antibodies targeting different epitopes of TREH to validate findings. Like other research antibodies, TREH antibodies may exhibit variable performance across different experimental conditions, requiring careful interpretation of seemingly contradictory results .

How can computational approaches enhance TREH antibody specificity?

Recent advances in computational biology offer opportunities for designing TREH antibodies with enhanced specificity:

These approaches allow researchers to design antibodies with customized specificity profiles beyond what might be available through traditional methods . Such computational methods have been successfully applied to other antibody systems and could potentially enhance TREH antibody performance.

What is the optimal protocol for using TREH antibodies in immunohistochemistry?

While specific protocols may vary depending on the particular TREH antibody, a general IHC protocol includes:

• Tissue preparation: Fix tissues in 10% neutral-buffered formalin and embed in paraffin

• Sectioning: Cut 4-6 μm sections and mount on positively charged slides

• Deparaffinization: Remove paraffin with xylene or substitute

• Antigen retrieval: Typically heat-induced epitope retrieval in citrate buffer (pH 6.0) or EDTA buffer (pH 9.0)

• Blocking: Block endogenous peroxidase activity and non-specific binding

• Primary antibody: Apply diluted TREH antibody (optimal dilution determined through titration)

• Detection: Apply appropriate detection system (e.g., polymer-based or avidin-biotin systems)

• Visualization: Develop with chromogen (e.g., DAB) and counterstain

• Mounting: Dehydrate, clear, and mount with permanent mounting medium

Optimization may be needed for specific tissue types or fixation conditions to achieve optimal staining results .

What ELISA configurations are most effective for TREH detection?

ELISA configurations for TREH detection depend on the research question and sample type:

• Sandwich ELISA: Most commonly used for TREH detection in complex biological samples

  • Capture antibody immobilizes TREH to the plate surface

  • Detection antibody (often conjugated to biotin) binds to captured TREH

  • Streptavidin-HRP provides signal amplification

  • Signal strength corresponds to TREH concentration

• Competitive ELISA: Useful when TREH is too small for simultaneous binding by two antibodies

  • TREH in the sample competes with plate-bound TREH for limited antibody binding

  • Higher TREH concentration in sample results in lower signal

The sandwich ELISA format typically offers higher sensitivity and specificity for TREH detection in complex samples like serum or tissue lysates .

How can TREH antibodies be properly cited in scientific publications?

Proper citation of TREH antibodies in publications is critical for reproducibility:

• Include complete identification information:

  • Antibody name and clone number

  • Host species and antibody type (monoclonal/polyclonal)

  • Supplier name and catalog number

  • Research Resource Identifier (RRID) from Antibody Registry

• Document key experimental parameters:

  • Dilution or concentration used

  • Incubation conditions

  • Detection method

The Antibody Registry provides persistent identifiers (RRIDs) for antibodies that can be cited in publications. This practice is now required or strongly encouraged by hundreds of scientific journals to improve research reproducibility . For example, a proper citation might read: "Rabbit Polyclonal Anti-TREH antibody (Atlas Antibodies, HPA042045, RRID:AB_XXXXXXX) was used at 1:200 dilution."

What controls are essential when using TREH antibodies?

Rigorous control experiments are necessary for meaningful TREH antibody results:

These controls help distinguish between true TREH detection and technical artifacts, particularly important when exploring TREH expression in novel contexts or when optimizing new experimental conditions .

How can researchers troubleshoot weak or non-specific TREH antibody signals?

When encountering weak or non-specific signals with TREH antibodies, consider these troubleshooting approaches:

• For weak signals:

  • Optimize antibody concentration through titration experiments

  • Modify antigen retrieval conditions (method, buffer, duration)

  • Extend primary antibody incubation time or temperature

  • Use more sensitive detection systems

  • Check sample handling and storage conditions

• For non-specific signals:

  • Increase blocking duration or concentration

  • Adjust washing conditions (duration, buffer composition)

  • Reduce primary antibody concentration

  • Consider alternative antibodies targeting different TREH epitopes

  • Verify tissue fixation and processing methods

Each experimental system may require specific optimization steps for optimal TREH antibody performance .

How do storage conditions affect TREH antibody performance?

Proper storage is critical for maintaining TREH antibody functionality:

• Temperature: Store according to manufacturer recommendations (typically -20°C for long-term storage of aliquots)

• Aliquoting: Divide into single-use aliquots to avoid freeze-thaw cycles

• Preservatives: Some antibodies contain preservatives (sodium azide) which may interfere with certain applications

• Stability: Monitor for signs of degradation including clouding, precipitation, or diminished signal

• Documentation: Record lot numbers and performance characteristics for each batch

Antibody degradation may manifest as reduced sensitivity, increased background, or complete loss of specific signal. Validation should be repeated when using new lots or antibodies that have been stored for extended periods .

How are TREH antibodies being used in emerging research fields?

TREH antibodies are finding applications in several cutting-edge research areas:

• Metabolic disease research: Investigating trehalose metabolism in diabetes and obesity models
