Overview
CD229 Antibody / Ly9 is a research-use antibody directed against CD229. It is supplied for use in common immunoassay contexts such as IHC-P, FACS (RUO).
Key elements and design rationale
- Target: CD229.
- Description (provided): T-lymphocyte surface antigen Ly-9 is a protein that in humans is encoded by the LY9 gene.
- Antibody type: Rabbit, Polyclonal (rabbit origin), Rabbit IgG.
- Format: Antigen affinity purified; Antigen affinity purified.
- Reported/predicted localization: Plasma membrane, cytoplasm.
- Species reactivity: tested: Human, Mouse, Rat.
- Immunogen (if provided): Amino acids YKAQINQRNFEVTTEEEFTLFVYEQLQEPQVTMK were used as the immunogen for the CD229 antibody..
The information above helps you match the antibody format to your assay context, interpret species-dependent differences, and anticipate how epitope context (isoforms, PTMs, or conformational state) may influence signal.
Biological background
T-lymphocyte surface antigen Ly-9 is a protein that in humans is encoded by the LY9 gene. This gene is mapped to 17q21.31. LY9 has also recently been designated CD229 (cluster of differentiation 229). LY9 belongs to the SLAM family of immunomodulatory receptors and interacts with the adaptor molecule SAP.
For curated annotations (gene/protein naming, domains, isoforms, and pathway links) for CD229, consult primary databases such as UniProt, NCBI Gene, and Ensembl.
Research relevance and current trends
- Context-dependent expression studies: researchers often examine CD229 abundance and localization across perturbations (genetic, pharmacologic, or environmental) to connect phenotype to molecular changes.
- Reagent reproducibility: there is growing emphasis on antibody specificity checks using orthogonal approaches (e.g., genetic perturbation or independent antibodies) and transparent reporting of clone/lot information.
- Multi-modal datasets: antibody-based readouts are increasingly combined with transcriptomics and imaging to relate protein-level measurements to cell-state transitions.
Common research applications
- Immunohistochemistry for spatial mapping of target expression across tissues and cell types.
- FACS: commonly used to detect or compare CD229 across experimental conditions (conceptual guidance only).
When comparing conditions, interpret changes in signal in the context of sample composition, expected localization, and any known isoform complexity for the target.
Notes for experimental interpretation
- Isoforms and PTMs: alternative splicing or post-translational modifications can change epitope accessibility and apparent molecular weight; interpret bands/signals accordingly.
- Cross-reactivity and matrix effects: background binding can vary by sample type, species, and blocking/detection chemistries; include appropriate negative controls.
- Control concepts: where feasible, use genetic perturbation (KO/KD/overexpression), orthogonal assays, or independent antibodies to support specificity claims.
Antibody considerations: Polyclonal reagents may recognize multiple epitopes and can increase sensitivity but may show broader binding profiles, while monoclonal clones provide a single-epitope readout that can improve consistency across experiments. If a conjugate is listed, the antibody supports more direct detection workflows; otherwise, it is typically used with a compatible secondary antibody.
Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
