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: Can bind to the surface of B-lymphoma cells, but not T- lymphoma cells, consistent with a function as a secreted mediator acting upon B-cells.

Cellular localization: Nucleus .

Tissue details: Abundantly expressed in tonsil, lymph node, and trachea; strong expression in prostate; lower expression in thyroid, stomach, and colon. .

Background: Microfibril-associated glycoprotein 3 (MFAP3), is a member of the MFAP family which play a role in microfibril assembly, elastinogenesis, and tissue homeostasis. The family members were identified as potential components of fibrillin-containing microfibrils, but they do not share structural similarities. MFAP3 is found in ocular zonules. Human MFAP3 is a serine-rich acidic protein located in zonular fibers and consists of an extracellular domain (ECD) containing one Ig-like C2-type domain, a single transmembrane domain, and a cytoplasmic domain. Within the ECD, mature human MFAP3 shares 74% amino acid sequence identity with mouse and rat MFAP3. Among MFAP3-related pathways are degradation of the extracellular matrix and elastic fiber formation. MFAP is a candidate gene for heritable diseases affecting microfibrils.

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.
• 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.
