- Antibody format: Polyclonal; Rabbit IgG
- Species context: Host: Rabbit, Reactivity: Human
- Purification: Immunogen affinity purified.
- Immunogen: E.coli-derived human SPOCK3 recombinant protein (Position: Q104-H396).

- Provided application(s): WB, IHC, IF, ICC, Flow, ELISA
These attributes help contextualize how the antibody is commonly selected (host/clonality/isotype/label) and how signals are interpreted across sample types and assay formats.
Biological background
Function: Lymphocyte inhibitory receptor which inhibits lymphocytes during immune response.
Cellular localization: Membrane.
Tissue details: Wide tissue distribution (highest in the pancreas and very low in brain). Closely associated with the basal layer of cells in epithelia and the endothelium of blood vessel walls.
Background: This gene encodes a member of a novel family of calcium-binding proteoglycan proteins that contain thyroglobulin type-1 and Kazal-like domains. The encoded protein and may play a role in adult T-cell leukemia by inhibiting the activity of membrane-type matrix metalloproteinases. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene
Cross reactivity: No cross-reactivity with other proteins.
Research relevance and current trends
- Quantitative and spatial profiling: expression patterns are increasingly studied across cell states using multiplex imaging and omics-informed validation.
- Isoforms and post-translational modifications: researchers often evaluate how isoform composition and PTMs can shift apparent molecular weight or localization.
- Context-aware interpretation: comparative studies commonly include perturbations (stimulation, inhibition, genetic models) to relate target changes to pathway behavior.
Common research applications
- Western blot (WB): compare relative target abundance and apparent size shifts (e.g., isoforms/PTMs) across conditions.
- Immunohistochemistry (IHC): assess distribution across tissue compartments and compare staining patterns between groups.
- Immunofluorescence / ICC: evaluate subcellular localization and co-localization with compartment markers.
- Flow cytometry: quantify target-positive populations and compare shifts after stimulation or differentiation.
Across these uses, researchers typically interpret changes in signal as relative differences between matched sample groups, considering sample preparation and biological context.
Notes for experimental interpretation
- Apparent molecular weight can vary due to isoforms, proteolysis, glycosylation, phosphorylation, and sample preparation differences.
- Species reactivity and epitope conservation can influence observed signal patterns, especially in cross-species studies.
- Control concepts: include appropriate negative controls (e.g., isotype controls where relevant) and, when feasible, genetic or orthogonal controls (KO/KD, peptide competition, or independent assays) to support interpretation.
For antibody reagents, monoclonal antibodies are often chosen for epitope consistency across lots, while polyclonals may recognize multiple epitopes and can show different background characteristics depending on context.
