Product Background
GPR25 is an orphan G protein-coupled receptor (GPCR) belonging to the chemokine receptor family. GPR25 is involved in immune regulation, chemokine signaling, cell migration, inflammatory responses, and GPCR-mediated signaling pathways.
GPR25 is studied in immunology, inflammation, receptor biology, signal transduction, cancer biology, and chemokine receptor research.
Antibody Development
HM0063 was generated by phage-display selection using a mouse-derived antibody library. Recombinant epitope-Fc fusion protein containing the GPR25 epitope sequence was used as the selection antigen. Following 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 GPR25 protein
Validation Data
ELISA Validation
ELISA demonstrated specific binding to recombinant epitope-Fc fusion antigen, while minimal binding was observed against Fc control protein.
Validation conditions:
- Well 1: Fc control protein
- Well 2: Epitope-Fc fusion protein
- Detection substrate: TMB
Note:
ELISA validation confirms binding to the epitope-Fc fusion antigen. Full-length GPR25 protein binding in solution has not been tested by ELISA.
Western Blot Validation – Recombinant Fusion Protein
Western blot analysis demonstrated specific recognition of recombinant MBP-epitope fusion protein expressed in BL21(DE3) cells, while no significant binding was observed against MBP control protein.
Validation conditions:
- Lane 1: MBP control protein
- Lane 2: MBP-epitope fusion protein
- Standard reducing Western blot
Western Blot Validation – Endogenous Full-Length Protein
Western blot analysis detected endogenous human GPR25 protein in human cell lines under reducing conditions.
Validated samples:
- 293T cells
- HeLa cells
- HepG2 cells
Detection condition:
- Standard reducing Western blot
- HRP-conjugated anti-mouse secondary antibody
Observed bands:
- Major bands observed near expected GPR25 molecular weight
