Function
Tumor suppressor. It blocks the growth, invasion, and metastatic properties of mammary tumors. As it does not undergo the S (stressed) to R (relaxed) conformational transition characteristic of active serpins, it exhibits no serine protease inhibitory activity (By similarity).
Alternative names
Pi5, Spi5, Spi7, Serpinb5, Serpin B5, Maspin, Peptidase inhibitor 5, PI-5

Notes
Mouse MASPIN ELISA Kit (ab238270) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of MASPIN protein in tissue extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate Mouse MASPIN with 18.2 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (Pre-coated 384 well Microplate SimpleStep ELISA® ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

- Activity summary
MASPIN also known as SERPINB5 is a non-inhibitory serine protease inhibitor with a mass of approximately 42 kDa. It functions mechanically to regulate cell adhesion migration apoptosis and angiogenesis. MASPIN localizes mainly in the cytoplasm and nucleus and expresses predominantly in epithelial cells including those in the mammary gland prostate and keratinocytes in the skin. It acts as a tumor suppressor and researchers often use immunohistochemistry (IHC) to study its expression patterns in various tissues.
- Biological function summary
MASPIN influences apoptosis and cell motility playing a critical role in tumor suppression. It does not form part of a complex but interacts directly with extracellular matrix components. MASPIN can inhibit angiogenesis by reducing the proliferation and migration of endothelial cells. Scientists have noted its role in maintaining normal cell architecture and inhibiting tumor cell invasion.
- Pathways
Researchers place MASPIN in important signaling networks impacting cancer progression and metastasis. It participates in the PI3K/AKT pathway thereby influencing cell growth and survival. MASPIN also intersects with TGF-β signaling and related proteins like SMAD which mediate growth arrest and apoptosis. By altering these pathways MASPIN helps modulate responses to cellular stress and inhibit lethal growth in cancer cells.
- Associated diseases and disorders
MASPIN often associates with breast and prostate cancers. Its expression inversely correlates with tumor progression suggesting a protective role. MASPIN's interaction with proteins like p53 highlights its contribution to tumor suppression. Abnormal MASPIN presence links to aggressive disease phenotypes making it a potential biomarker for prognostic evaluation in oncology.

Example of mouse MASPIN standard curve in Sample Diluent NS.
Background-subtracted data values (mean +/- SD) are graphed.
Sandwich ELISA - Mouse MASPIN ELISA Kit (ab238270)
Interpolated concentrations of native MASPIN in mouse skin extract and mouse small intestine extract based on a 5 μg/mL and 1,500 μg/mL extract load, respectively. The concentrations of MASPIN were measured in duplicate and interpolated from the MASPIN standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean MASPIN concentration was determined to be 1,060.3 pg/mL in mouse skin extract and 2,199.6 pg/mL in mouse small intestine extract.
