Descrizione generale
Maspin (mammary serine protease inhibitor), also known as SERPINB5 (serpin family B member 5), was first identified in 1994. It is an epithelial-specific protein that belongs to the serine protease inhibitor superfamily known as serpin. It shows major expression in human mammary epithelial cells.
Recombinant human Maspin is a 42.2kDa non-glycosylated protein containing 375 amino acid residues.

Azioni biochim/fisiol
Maspin (mammary serine protease inhibitor) functions as a tumor suppressor in various types of cancer, such as breast cancer, prostate cancer etc. Its expression in cancer is thought to be controlled by DNA methylation, and in breast cancer and glioma its expression is silenced by abnormal methylation. In tissues of pulmonary adenocarcinoma (AC) patients, the mRNA expression of maspin is significantly increased, and hence, maspin mRNA expression might have potential as a prognosis marker in AC. Study in two MIBC (muscle invasive bladder cancer) cell lines (T24 and 5637) shows that overexpression of maspin can increase cisplatin chemosensitivity. In MIBC patients receiving cisplatin based neoadjuvant chemotherapy, the expression of maspin correlates with the prognosis.

Ricostituzione
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

Maspin (mammary serine protease inhibitor) was identified in 1994 by subtractive hybridization analysis of normal mammary tissue and breast cancer cell lines. Subsequently, emerging evidence portrays maspin as a multifaceted protein, interacting with diverse group of intercellular and extracellular proteins
