Product Background
G-protein coupled receptor 84 (GPR84) is an immune-associated G protein-coupled receptor involved in inflammatory signaling, innate immune responses, macrophage biology, metabolic inflammation, and receptor-mediated signal transduction. GPR84 has been studied in inflammation, immune regulation, fibrosis, metabolic disease, and cancer-related signaling pathways.
GPR84 is a useful target for researchers studying GPCR biology, immunology, inflammatory disease mechanisms, receptor pharmacology, and immune-metabolic signaling.
Antibody Development
HM0061 was generated by phage-display selection using a mouse-derived antibody library. A recombinant epitope-Fc fusion protein containing the GPR84 epitope sequence was used as the selection antigen. After identification of the initial antibody candidate, structure-guided affinity optimization was performed to improve binding affinity and specificity.
The optimized antibody was reconstructed as a full-length mouse IgG1 recombinant antibody and expressed in HEK293 cells.
Binding and specificity were evaluated by:
- ELISA using recombinant epitope-Fc fusion antigen
- Western blot using recombinant MBP-epitope fusion protein
- Western blot detection of endogenous human GPR84 protein
Validation Data
ELISA Validation
ELISA demonstrated specific binding to recombinant epitope-Fc fusion antigen, while minimal binding was observed against Fc-only control protein.
Validation conditions:
- Fc control protein
- Epitope-Fc fusion protein
- Detection substrate: TMB
Note: ELISA validation confirms binding to epitope-Fc fusion antigen. Full-length GPR84 protein binding in solution has not been tested by ELISA.
Western Blot Validation – Recombinant Fusion Protein
Western blot analysis confirmed specific recognition of recombinant MBP-epitope fusion protein, with minimal signal against MBP control protein.
Validation conditions:
- MBP control protein
- MBP-epitope fusion protein
- Standard reducing Western blot
Western Blot Validation – Endogenous Full-Length Protein
Western blot analysis detected endogenous human GPR84 protein in human cell lysates under reducing conditions.
Validated samples:
- 293T cells
- HeLa cells
- HepG2 cells
Observed bands:
- Major immunoreactive bands were detected around 45–50 kDa, consistent with the expected molecular weight range of human GPR84.
- Additional lower molecular weight bands may represent processed receptor fragments, degradation products, alternatively modified receptor forms, or GPCR-associated species.
