Mammaglobin-A precursor (2-10)

Mammaglobin-A precursor (2-10) is a synthetic peptide fragment derived from the N-terminal region of the human mammaglobin-A protein, a member of the secretoglobin family. Recognized for its tissue-specific expression, particularly in mammary epithelium, this peptide serves as a valuable tool in molecular and cellular studies targeting breast tissue markers. The sequence encompasses amino acids 2 through 10 of the precursor protein, providing a defined epitope for experimental applications. Its unique biochemical properties and relevance to breast tissue biology make it an important component for researchers investigating protein-protein interactions, antigenicity, and biomarker discovery within the context of mammaglobin-A.

Epitope mapping: Researchers utilize the 2-10 fragment of the mammaglobin-A precursor to define and characterize antibody binding sites. By incorporating this peptide into immunoassays or peptide arrays, scientists can pinpoint specific antigenic determinants recognized by monoclonal or polyclonal antibodies. This approach is essential for the development and validation of antibody-based detection methods, facilitating both the study of immune recognition and the assessment of antibody specificity for mammaglobin-A.

Antibody production: The defined sequence of this peptide fragment makes it an effective immunogen for raising targeted antibodies against mammaglobin-A. By conjugating the peptide to a suitable carrier protein, immunization protocols can generate high-affinity antibodies that selectively recognize the N-terminal epitope. These antibodies are critical reagents for downstream applications such as immunoblotting, immunohistochemistry, and ELISA, where specificity to mammaglobin-A is required for reliable detection and quantification in research samples.

Biomarker research: The peptide serves as a reference standard or positive control in studies focused on breast tissue-specific markers. Its precise sequence allows for the calibration and validation of analytical platforms designed to detect mammaglobin-A expression. In translational research, the use of this fragment supports the exploration of mammaglobin-A as a potential biomarker, enabling the assessment of assay sensitivity, selectivity, and reproducibility in the context of breast tissue analysis.

Peptide-based assay development: The fragment's well-defined nature supports its use in the design and optimization of peptide-based assays. Synthetic peptides like this are often incorporated into multiplexed detection systems, solid-phase binding assays, or competitive inhibition formats. Such applications benefit from the peptide's stability and reproducibility, which are essential for establishing robust, quantitative assays for mammaglobin-A-related research.

Protein interaction studies: The N-terminal sequence of mammaglobin-A represented by this peptide is of interest for mapping protein-protein interactions involving secretoglobins or related signaling pathways. By utilizing the fragment in binding assays or affinity purification protocols, researchers can investigate interaction partners and elucidate molecular mechanisms underpinning mammaglobin-A function. These studies contribute to a deeper understanding of the biological roles of secretoglobins in mammary tissue and related cellular processes.
