THNSL2 Antibody

What is THNSL2 and why are antibodies against it valuable for research?

THNSL2 (Threonine Synthase-Like 2) is a protein belonging to the threonine synthase family. It is also known by the aliases SOFAT, TSH2, and FLJ10916 . The protein has garnered research interest particularly because one isoform functions as a secreted osteoclastogenic factor produced by activated T-cells via a calcineurin-independent pathway . Antibodies against THNSL2 are valuable tools for studying its expression, localization, and function across multiple research areas including immunology and bone metabolism.

What are the key specifications to consider when selecting a THNSL2 antibody?

When selecting a THNSL2 antibody, researchers should evaluate several critical specifications:

• Target region specificity: Antibodies are available targeting different regions including N-terminal, middle, and internal regions

• Host species: Most commonly rabbit, with some goat-derived options

• Clonality: Primarily polyclonal antibodies are available

• Species reactivity: Consider cross-reactivity with your experimental model (human, mouse, rat, etc.)

• Validated applications: Ensure the antibody is validated for your specific application (WB, ELISA, IHC, IF)

• Conjugation: Available as unconjugated or conjugated to reporters like HRP, FITC, or Biotin

What is the predicted molecular weight of THNSL2 and how does this impact experimental design?

THNSL2 has a calculated molecular weight of approximately 54.116 kDa . This information is crucial when performing Western blot analysis to ensure correct band identification. When designing experiments, researchers should consider:

• Proper selection of molecular weight markers

• Appropriate gel percentage for optimal separation in this weight range

• Transfer conditions optimized for proteins of this size

• Potential post-translational modifications that may alter the observed molecular weight

What are the optimal conditions for using THNSL2 antibodies in Western blotting?

For optimal Western blot results with THNSL2 antibodies:

• Sample preparation: Use appropriate cell or tissue lysates with protease inhibitors

• Recommended dilution range: 1:500-1:1000 for most THNSL2 antibodies

• Blocking solution: PBS with protein blocker to minimize background

• Incubation conditions: Follow manufacturer's recommendations for time and temperature

• Detection: Use appropriate secondary antibody and visualization method

• Expected band size: Approximately 54 kDa

Always perform initial titration experiments to determine the optimal antibody concentration for your specific sample type and detection method.

How should THNSL2 antibodies be stored and handled to maintain optimal activity?

To maintain THNSL2 antibody effectiveness:

• Long-term storage: Store at -20°C for up to one year

• Short-term/frequent use: Store at 4°C for up to one month

• Avoid repeated freeze-thaw cycles which can degrade antibody quality and performance

• Store in original buffer conditions (typically PBS with 0.09% sodium azide and 2% sucrose or 50% glycerol)

• Handle according to safety guidelines, particularly when sodium azide is present

• Aliquot antibodies upon receipt to minimize freeze-thaw cycles for long-term storage

What species cross-reactivity can be expected with THNSL2 antibodies?

THNSL2 antibodies exhibit varying degrees of cross-reactivity based on sequence homology:

How can researchers validate the specificity of THNSL2 antibodies for their experimental systems?

Comprehensive validation of THNSL2 antibodies should include:

• Positive controls: Use tissues/cells known to express THNSL2

• Negative controls: Include tissues/cells lacking THNSL2 expression

• Blocking peptide competition: Pre-incubate with the immunogenic peptide to demonstrate specificity

• Multiple antibodies approach: Use antibodies targeting different epitopes of THNSL2 to confirm consistent results

• Knockdown/knockout validation: Compare signal between normal and THNSL2-depleted samples

• Sequence analysis: Confirm epitope conservation when working with non-human species

What considerations are important when studying the SOFAT isoform of THNSL2?

When specifically investigating the SOFAT isoform of THNSL2:

• Subcellular localization: SOFAT is secreted by activated T-cells

• Secretion pathway: Occurs via a calcineurin-independent mechanism

• Functional significance: Induces osteoclast formation in a RANKL-independent manner

• Detection methods: Consider using antibodies that recognize secreted forms in culture supernatants or body fluids

• T-cell activation methods: Design appropriate stimulation protocols to induce SOFAT secretion

• Antibody epitope: Select antibodies targeting regions present in the secreted form

These considerations ensure targeted investigation of the specific SOFAT function among THNSL2's potential roles.

What immunogen characteristics should be considered when selecting THNSL2 antibodies for specific applications?

The immunogen used to generate THNSL2 antibodies significantly impacts their performance characteristics:

• Epitope location: Antibodies target various regions including:

  • N-Terminal region (AA 232-261)

  • Middle region (directed toward the synthetic peptide sequence LPLVEVVVPT GAAGNLAAGY IAQKIGLPIR LVVAVNRNDI IHRTVQQGDF)

  • Internal regions (AA 295-441, AA 192-204, AA 811-860)

• Immunogen format: Synthetic peptides versus recombinant proteins

• Affinity purification: Most commercial antibodies are affinity-purified against the immunogen

• Application suitability: Different epitopes may perform better in native versus denatured conditions

Carefully matching immunogen characteristics to your experimental needs improves likelihood of successful results.

What are common issues with THNSL2 antibody performance in immunohistochemistry?

When troubleshooting immunohistochemistry with THNSL2 antibodies:

• No signal:

  • Verify THNSL2 expression in your sample tissue

  • Optimize antigen retrieval methods

  • Increase antibody concentration

  • Extend incubation times

  • Use more sensitive detection systems

• High background:

  • Increase blocking step duration

  • Dilute primary and secondary antibodies

  • Add additional washing steps

  • Use more specific blocking reagents

  • Consider tissue autofluorescence (for IF applications)

• Non-specific staining:

  • Validate antibody specificity using controls

  • Compare with known expression patterns

  • Use peptide competition controls

  • Consider different antibody clones

How can researchers optimize THNSL2 antibody dilutions for different applications?

Optimal antibody dilution varies by application and specific antibody:

• Western blotting: Typically 1:500-1:1000

• Immunohistochemistry: Often 1:100-1:500

• Immunofluorescence: Generally 1:100-1:400

• ELISA: Usually 1:1000-1:10000

The optimization process should include:

• Initial broad range titration

• Narrower secondary titration near optimal range

• Assessment of signal-to-noise ratio

• Documentation of optimal conditions for reproducibility

• Consideration of different blocking reagents to improve specificity

As noted by manufacturers, "Optimal working dilutions should be determined experimentally by the investigator" .

What strategies can address cross-reactivity concerns when using THNSL2 antibodies across different species?

To address cross-species reactivity concerns:

• Sequence analysis:

  • Compare epitope sequences across target species

  • Reference predicted reactivity percentages from manufacturers

  • Focus on antibodies with high homology to your species of interest

• Experimental validation:

  • Test antibodies on known positive controls from your species

  • Perform Western blots to confirm proper molecular weight detection

  • Compare staining patterns with published expression profiles

  • Adjust protocols (concentration, incubation time) for each species

  • Consider custom antibody development for poorly conserved regions

This systematic approach ensures reliable cross-species results while minimizing false positives or negatives.
