Overview
This is a polyclonal anti-LGR5 antibody raised in Rabbit, conjugated with FITC. It is designed to detect LGR5 protein in Human and supports researchers working in signal transduction contexts.
Key elements and design rationale
- Immunogen: Recombinant Human Leucine-rich repeat-containing G-protein coupled receptor 5 protein (241-352AA) — determines the epitope region; confirm compatibility with sample preparation and expected post-translational modifications.
- Host species (Rabbit): Requires anti-rabbit-IgG secondary reagents for indirect detection.
- Polyclonal format: Recognizes multiple epitopes for robust signal; inherent lot-to-lot variability requires appropriate controls.
- Isotype (IgG): Matched secondary antibodies and isotype controls required. Compatible with standard Protein A/G purification workflows.
- Purification (Protein G purification): Enriches for specific immunoglobulin classes; reduces non-specific background vs. crude antisera.
- FITC conjugate: Direct fluorescence (Ex ~490/Em ~525 nm). Protect from light; use antifade reagents for slide-based applications.
Biological background
LGR5 (also referred to as FEX, G protein coupled receptor 49, G protein coupled receptor 67, g protein-coupled receptor fex, G-protein coupled receptor 49, G-protein coupled receptor 67, G-protein coupled receptor HG38, GPCR GPR49, GPR 49, GPR 67, GPR49, GPR67, GRP 49, GRP49, HG 38, HG38, Leucine rich repeat containing G protein coupled receptor 5 , Leucine-rich repeat-containing G-protein coupled receptor 5, LGR 5, LGR5, LGR5_HUMAN, MGC117008, Orphan G protein coupled receptor HG38) is a protein target studied in Human systems. Expression, subcellular localization, and post-translational modifications vary across cell types and disease states — factors critical to antibody-based detection design. Consult UniProt, NCBI Gene, and primary literature for current annotation of LGR5 biology in signal transduction.
Common research applications
- Refer to product documentation for confirmed application data.
Notes for experimental interpretation
- Isotype controls: Use an isotype-matched (IgG from Rabbit) control at equivalent concentration to assess non-specific background.
- Cross-reactivity: Polyclonal preparations may cross-react with related proteins. Orthogonal validation (siRNA, KO lysate) is recommended.
- Matrix effects: Sample matrix can affect performance; pilot dilution linearity and spike-recovery experiments are advised for quantitative studies.
- Species reactivity: Confirmed for Human. Extrapolation to untested species requires empirical validation.
This product is a polyclonal antibody purified from rabbit antiserum.
LGR5 is a protein target in Human biology. This polyclonal antibody raised in Rabbit is designed to detect LGR5 in immunoassay applications, with IgG isotype.
Reported reactive against Human. Immunogen derived from Human. Cross-reactivity with other species should not be assumed without documented data or empirical testing.
Application data not specified; consult the product datasheet or contact BioHippo support.
FITC direct fluorescence (Ex ~490/Em ~525 nm). Protect from light; use antifade for slide applications.
(1) Isotype control — IgG from Rabbit at matching concentration; (2) Positive control — known LGR5-expressing cell/tissue; (3) Negative control — knockdown/knockout sample for specificity; (4) Dilution linearity — verify proportional signal decrease in your matrix.
