OR10AG1 is a poorly studied receptor with no known therapeutic targets or small-molecule interactions . Antibodies like OR10AG1 are critical for:
OR10AG1 (Olfactory Receptor, Family 10, Subfamily AG, Member 1) is a human olfactory receptor protein with a molecular weight of approximately 34 kDa. It is also known by alternative names including Olfactory receptor OR11-160 . OR10AG1 antibodies are immunological reagents raised against specific epitopes of this protein, typically produced in rabbits and available in various formats:
Host species: Predominantly rabbit-derived polyclonal antibodies
Clonality: Both polyclonal (most common) and monoclonal options are available
Immunogen regions: Several epitope regions are targeted, including amino acids 214-263, 231-280, and 235-263
Conjugations: Available as unconjugated or conjugated to detection molecules such as PE (phycoerythrin), biotin, or APC (allophycocyanin)
The diverse range of available antibodies reflects the varying experimental needs in OR10AG1 research, from basic protein detection to complex immunological assays.
Experimental design when working with OR10AG1 antibodies requires careful planning to ensure reliable, reproducible results. Consider implementing these methodological approaches:
Establish a clear hypothesis: Begin with a specific, testable hypothesis about OR10AG1 that guides your experimental approach .
Use a randomized block design: When comparing OR10AG1 expression across different experimental conditions, implement a randomized block design to control for confounding variables .
Include proper controls: Essential controls include:
Consider between-subjects vs. within-subjects design: For studies examining OR10AG1 under multiple conditions, carefully choose between comparing different samples (between-subjects) or the same samples under different treatments (within-subjects) .
Determine sample size: Ensure adequate statistical power through appropriate sample size calculations based on expected effect sizes .
The choice between OR10AG1 antibodies targeting different epitopes (amino acid regions) can significantly impact experimental outcomes:
When selecting an OR10AG1 antibody, researchers should consider:
Protein structure: C-terminal antibodies (like those targeting AA 235-263) may perform better if N-terminal regions are obscured in the native protein conformation.
Post-translational modifications: Modifications near certain epitopes may affect antibody binding. Review the target region for potential phosphorylation sites or other modifications.
Splice variants: Different epitope-targeting antibodies may detect different isoforms of OR10AG1.
Experimental application: Some epitope regions may perform better in certain applications (WB vs. IF) due to differences in protein denaturation and epitope accessibility.
This strategic selection of epitope-specific antibodies can significantly improve detection sensitivity and specificity in OR10AG1 research.
For optimal Western blot results with OR10AG1 antibodies, follow this detailed protocol:
Sample preparation:
Lyse cells or tissues in an appropriate lysis buffer containing protease inhibitors
Determine protein concentration using a compatible assay (BCA or Bradford)

Heat samples at 95°C for 5 minutes
Gel electrophoresis:
Transfer:
Transfer proteins to a PVDF or nitrocellulose membrane
Use a wet transfer system at 100V for 1 hour or 30V overnight at 4°C
Blocking:
Block the membrane with 5% non-fat dry milk or BSA in TBST for 1 hour at room temperature
Primary antibody incubation:
Washing:
Wash membrane 3× with TBST, 5-10 minutes each
Secondary antibody incubation:
Detection:
This protocol has been validated for detecting OR10AG1 in RAW264.7 cell lysates and can be adapted for other sample types.
Proper storage and handling are crucial for preserving OR10AG1 antibody function and extending shelf life:
Shipping conditions:
Long-term storage:
Working solution handling:
When preparing diluted working solutions, use sterile tubes and buffers
Store diluted antibody at 4°C for short-term use (1-2 weeks)
For dilutions containing carrier proteins like BSA, add sodium azide (0.02%) as a preservative
Formulation considerations:
Stability indicators:
Monitor for visible precipitation or color changes
If protein aggregation is observed, the antibody may have reduced activity
Following these storage guidelines will help ensure consistent performance across experiments and maximize the usable lifetime of OR10AG1 antibodies.
Implementing proper controls is essential for validating results with OR10AG1 antibodies:
Primary antibody controls:
Isotype controls: Use matched rabbit IgG at the same concentration as the OR10AG1 antibody. Products A82272 and A17360 are suitable isotype controls for rabbit polyclonal antibodies .
Peptide competition: Pre-incubate the antibody with the immunizing peptide prior to application to confirm specificity. Blocking peptides are available specifically for OR10AG1 antibodies .
Secondary antibody controls:
No primary control: Apply only secondary antibody to identify potential non-specific binding
Recommended secondaries: For rabbit-derived OR10AG1 antibodies, suitable secondaries include:
Sample-related controls:
Positive tissue/cell control: Include samples known to express OR10AG1
Negative tissue/cell control: Include samples known not to express OR10AG1
Loading control: Use antibodies against housekeeping proteins (β-actin, GAPDH) to verify equal loading in Western blots
Technical controls:
Serial dilution: Test a range of antibody dilutions to identify optimal signal-to-noise ratio
Cross-reactivity assessment: Test the antibody on non-target tissues to assess potential cross-reactivity
Implementing these controls helps distinguish specific from non-specific signals and validates the reliability of OR10AG1 detection in your experimental system.
When working with low-abundance OR10AG1 expression, several strategies can enhance detection sensitivity:
Sample enrichment techniques:
