Description

Mammaglobin-A Human Recombinant (Fc Chimera) produced in HEK cells is a single, glycosylated, polypeptide chain (Gly19-Phe93) containing a total of 321 amino acids, having a calculated molecular mass of 36.3kDa. The SCGB2A2 protein is fused to a 2 aa C-terminal linker, a 6 aa C-terminal His tag, a 7 aa TEV site and a 231 aa Human IgG1 fragment (Pro100-Lys330).

Product Specs

Introduction
The mammaglobin gene, initially discovered through a differential screening method aimed at identifying new breast cancer-related genes in humans, encodes a 10 kDa glycoprotein. This gene exhibits a distant relationship to a family of epithelial secretory proteins, including rat estramustine-binding protein/prostatein and human Clara cell 10 kDa protein (CC10)/uteroglobin. Mammaglobin, a mammary-specific member of the uterglobin family, is known to be overexpressed in human breast cancer. Studies suggest that mammaglobin is one of the first relatively mammary-specific and mammary-sensitive markers (85%). Its potential value in evaluating tumors of unknown primary sites, especially when used in conjunction with BRST-2 (GCDFP-15) and ER, is currently being investigated. Located on chromosome 11 at locus 11q13, SCGB2A2 (the mammaglobin gene) belongs to the secretoglobin superfamily. This group consists of small, dimeric proteins that are often secreted and glycosylated. Expressed primarily in mucosa, secretoglobins are thought to be involved in various cellular processes such as cell signaling, immune response, and chemotaxis, and may also function as transporters for steroid hormones in humans.

Physical Appearance

Sterile filtered lyophilized powder.

Formulation

SCGB2A2 was filtered (0.4 μm) and lyophilized from a 0.5 mg/ml solution in PBS buffer containing 5% (w/v) Threalose at a pH of 7.4.

Solubility

To prepare a working stock solution, it is recommended to add deionized water to achieve a concentration of approximately 0.5 mg/ml and allow the lyophilized pellet to dissolve completely. Please note that this product is not sterile. Before using it on cell culture, it is essential to filter the product through an appropriate sterile filter.

Stability

Store the lyophilized protein at -20 °C. To prevent repeated freezing and thawing cycles, it is advisable to aliquot the product after reconstitution. Once reconstituted, the protein can be stored at 4 °C for up to 5 days.

Purity
Greater than 95.0% purity as determined by SDS-PAGE analysis.

Product Science Overview

Introduction

Mammaglobin-A, also known as secretoglobin family 2A member 2 (SCGB2A2), is a protein encoded by the SCGB2A2 gene in humans . This protein is a member of the secretoglobin superfamily, which consists of small, dimeric, secreted, and sometimes glycosylated proteins . Mammaglobin-A is primarily expressed in the mammary tissue and has gained significant attention due to its potential role in breast cancer diagnosis and treatment .

Structure and Function

Mammaglobin-A is a 93-amino acid glycoprotein . It forms a heterodimer with lipophilin B, another member of the secretoglobin family . The exact function of Mammaglobin-A remains unclear, but it is believed to be involved in cell signaling, immune response, and chemotaxis . Additionally, secretoglobins, including Mammaglobin-A, may serve as transporters for steroid hormones in humans .

Clinical Significance

Mammaglobin-A expression is highly specific to mammary tissue, making it a valuable marker for identifying and detecting disseminated breast cancer cells . Its expression is frequently observed in breast epithelial cells, and it is used as a diagnostic marker for breast cancer . Moreover, Mammaglobin-A represents an attractive target for novel therapies involving adaptive T cell transfer and antitumor vaccines for breast cancer patients .

Research and Applications

Recent studies have shown that Mammaglobin-A expression is not limited to breast cancers. It has been found in tumors derived from the female genital tract and salivary glands . Immunohistochemistry analysis of a tissue microarray containing samples from various tumor types and normal tissues revealed Mammaglobin-A positivity in several tumor categories . This highlights the potential use of anti-Mammaglobin therapies in other Mammaglobin-positive tumor types .
