Key elements and design rationale

• Target: SPAG7 — DAP3 binding cell death enhancer 1 (coiled-coil domain containing 36). Alternative names: Interactor of HORMAD1 protein 1; Cancer/testis antigen 74; CT74; Coiled-coil domain-containing protein 36; CCDC36; IHO1
• Antibody format: Polyclonal; Rabbit IgG
• Species context: Host: Rabbit, Reactivity: Human,Mouse,Rat
• Purification: Immunogen affinity purified.
• Immunogen: E.coli-derived human SPAG7 recombinant protein (Position: M1-D199).
• Molecular weight context: observed 35 kDa, calculated 64099 MW (reported)
• 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: Required for DNA double-strand breaks (DSBs) formation in unsynapsed regions during meiotic recombination. Probably acts by forming a complex with MEI4 and REC114, which activates DSBs formation in unsynapsed regions, an essential step to ensure completion of synapsis. Not required for HORMAD1 functions in pairing-independent synaptonemal complex formation, ATR recruitment to unsynapsed axes, meiotic silencing of unsynapsed chromatin (MSUC) or meiotic surveillance.

Cellular localization: Chromosome.

Tissue details: Detected in liver, skeletal muscle, kidney, pancreas, spleen, thyroid, testis, ovary, small intestine and colon.

Background: Sperm-associated antigen 7 is a protein that in humans is encoded by the SPAG7 gene. SPAG7 (sperm-associated antigen 7) is a 227 amino acid nuclear protein that contains one R3H domain and is expressed in fetal brain. The gene that encodes SPAG7 consists of approximately 8,612 bases and maps to human chromosome 17p13.2. Encoding more than 1,200 genes, chromosome 17 comprises over 2.5% of the human genome. 2 key tumor suppressor genes are associated with chromosome 17, namely, p53 and BRCA1. Tumor suppressor p53 is necessary for maintenance of cellular genetic integrity by moderating cell fate through DNA repair versus cell death. Malfunction or loss of p53 expression is associated with malignant cell growth and Li-Fraumeni syndrome. Like p53, BRCA1 is ly involved in DNA repair, though specifically it is recognized as a genetic determinant of early onset breast cancer and predisposition to cancers of ovary, colon, prostate gland and fallopian tubes.

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.
