OR1L6 is a human olfactory receptor that binds odorant molecules in the nasal epithelium, initiating neuronal signals for smell perception . Antibodies against OR1L6 enable researchers to study its expression, localization, and function in physiological and pathological contexts. These antibodies are typically polyclonal, produced in rabbits, and validated for applications like Western blotting (WB) and immunofluorescence (IF) .

OR1L6 (Olfactory Receptor Family 1 Subfamily L Member 6) is an olfactory receptor protein that functions in odorant detection. Olfactory receptors interact with odorant molecules to initiate neuronal responses that trigger smell perception .
Current commercially available OR1L6 antibodies are validated for multiple applications:
Western Blotting (WB): Typically at dilutions of 1:500-1:2000
ELISA: Generally at dilutions of 1:10000-1:40000
Immunofluorescence (IF): Recommended at dilutions of 1:100-1:1000
Immunocytochemistry (ICC): Used at dilutions similar to IF applications
Most OR1L6 antibodies are rabbit polyclonal antibodies that recognize human OR1L6, though some demonstrate cross-reactivity with rat and mouse samples .
OR1L6 antibodies require specific storage conditions to maintain their functionality:
Important handling notes:
Allow antibodies to equilibrate to room temperature before opening
Sodium azide is a hazardous substance that should be handled by trained personnel only
Avoid repeated freeze-thaw cycles as this can lead to protein denaturation and loss of antibody activity
Antibody validation is critical for ensuring experimental reproducibility. The "antibody characterization crisis" has cast doubt on many scientific results due to inadequately characterized antibodies . For OR1L6 antibody validation:

Western Blotting Issues:
Immunofluorescence Issues:
Distinguishing true OR1L6 signal from artifacts requires rigorous controls and experimental design:
Multiple detection methods approach:
Combine at least two independent detection techniques (e.g., Western blot plus immunofluorescence)
Correlate antibody-based detection with mRNA expression data when possible
Advanced validation using genetic approaches:
Use CRISPR/Cas9 knockout models as negative controls
Consider siRNA knockdown to create partial expression models for validation
Epitope competition assays:
Custom specificity profile design:
Accurate quantification of OR1L6 requires attention to several factors:
Quantification methodology comparison:
Critical considerations:
Due to potential tissue-specific post-translational modifications, validate antibody performance in each tissue type
For absolute quantification, include recombinant OR1L6 protein standards
When comparing expression between samples, normalize to appropriate housekeeping proteins
Consider potential differences in epitope accessibility between tissue types due to protein interactions or conformational changes
Investigating OR1L6 receptor-ligand interactions requires specialized experimental designs:
Proximity ligation assays:
Use OR1L6 antibody in combination with antibodies against potential interacting proteins

Antibody blocking studies:
Co-immunoprecipitation with staged validation:
Use OR1L6 antibodies for pull-down experiments
Confirm specificity using appropriate controls:
Isotype control antibodies
OR1L6 blocking peptides
Reciprocal co-IP with antibodies against predicted interacting partners
Advanced computational antibody optimization:
Recent research has demonstrated "computational design of antibodies with customized specificity profiles"
This approach can generate antibodies with "specific high affinity for a particular target ligand, or with cross-specificity for multiple target ligands"
The technique combines "biophysics-informed modeling and extensive selection experiments"
Detecting low-abundance OR1L6 protein requires optimization strategies:
Signal amplification methods:
Tyramide signal amplification (TSA):
Can increase detection sensitivity by 10-100 fold
Protocol: After primary OR1L6 antibody incubation, use HRP-conjugated secondary antibody followed by tyramide-fluorophore treatment
Requires careful optimization of reaction time to prevent background signal
Sample enrichment techniques:
Enhanced antibody selection:
Multi-epitope detection strategy:
Use multiple antibodies targeting different regions of OR1L6 simultaneously
This approach increases signal while maintaining specificity
Protocol optimization table:
| Technique | Standard Protocol | Enhanced Protocol for Low Abundance |
|---|---|---|
| Western Blot | 1:1000 dilution, 4°C overnight | 1:500 dilution, 4°C for 48 hours with gentle rocking |
| ELISA | 1:10000-1:40000 dilution | Two-step amplification with biotinylated secondary antibody and streptavidin-HRP |
| IF/ICC | 1:200-1:1000 dilution | 1:100 dilution with extended primary antibody incubation (24-48 hours at 4°C) |
With these optimized approaches, researchers can significantly improve detection sensitivity while maintaining experimental specificity.
Multidisciplinary research with OR1L6 antibodies requires careful planning:
