OR6C3 antibody targets the Olfactory Receptor Family 6, Subfamily C, Member 3 (OR6C3) protein, which belongs to the transmembrane protein family and is primarily involved in olfactory transduction pathways . The target protein, also known by alternative names including OST709 and HSA8, is identified in the UniProt database with the accession number Q9NZP0 . As a member of the G protein-coupled receptor superfamily, OR6C3 plays a significant role in sensory perception mechanisms, specifically in the detection of odorants and subsequent signal transduction processes.
Currently available commercial OR6C3 antibodies are primarily developed for research applications, including protein detection and characterization in human samples. These antibodies are designed to recognize specific epitopes within the OR6C3 protein structure, particularly the C-terminal region or internal segments of the human olfactory receptor .
The OR6C3 antibody is commercially available from multiple reputable sources, including AAT Bioquest, Antibodies-online, OriGene Technologies, ERPAN TECH, and Qtonics.

The commercially available OR6C3 antibodies are consistently produced in rabbit hosts, yielding polyclonal antibodies with IgG isotype characteristics . These antibodies are typically generated through immunization with synthetic peptides derived from specific regions of the human OR6C3 protein. The immunogens used generally represent either the C-terminal region or internal segments of the target protein, with manufacturers employing proprietary techniques to ensure optimal antibody production and specificity .
Most commercial OR6C3 antibodies target the C-terminal region of the human olfactory receptor 6C3 protein. For instance, Antibodies-online specifies that their product (ABIN7185363) is raised against a synthesized peptide derived from the C-terminal region of Human Olfactory receptor 6C3 . Similarly, Qtonics' antibody (QA14931) is generated against a synthesized peptide from the same region . OriGene's variant is produced against a synthesized peptide derived from the internal region of human OR6C3 . This targeted approach enhances the specificity of these antibodies for their intended applications.
All the surveyed commercial OR6C3 antibodies undergo rigorous purification processes, predominantly through affinity chromatography techniques. The antibodies are affinity-purified from rabbit antiserum using epitope-specific immunogen-based chromatography methods . This purification approach ensures high specificity and minimizes non-specific binding, which is crucial for reliable experimental outcomes.
The purified antibodies are typically supplied in liquid form with similar buffer compositions across manufacturers:
| Component | Typical Concentration | Function |

These ratios should be optimized for each specific antibody lot and experimental condition. Preliminary titration experiments are recommended to determine the optimal antibody concentration that provides the highest signal-to-noise ratio for your specific experimental system .
For optimal preservation of antibody activity:
Store antibodies at -20°C or -80°C as recommended by the manufacturer
Avoid repeated freeze-thaw cycles that can degrade antibody performance
Most OR6C3 antibodies are supplied in liquid format containing preservatives such as 50% glycerol, 0.5% BSA, and 0.02% sodium azide
Once thawed for use, antibodies can be stored at 4°C for short-term applications (1-2 weeks)
Handle with appropriate safety precautions, particularly for formulations containing sodium azide, which is classified as a hazardous substance requiring trained staff handling
Proper storage and handling practices are critical for maintaining antibody specificity and sensitivity across multiple experiments.
A comprehensive validation approach should include:
