Description

(29-41)-Ubiquicidine CAS NO 216867-99-1 is a high-purity synthetic peptide fragment, representing a specific sequence of the ubiquicidin antimicrobial peptide. This compound is of significant interest for research and development in the fields of antimicrobial agents and diagnostic imaging. It serves as a critical intermediate and reference standard for scientists and manufacturers developing novel therapeutics and diagnostic probes. Target users include pharmaceutical R&D teams, biotechnology companies, and academic research institutions focused on infectious diseases and molecular imaging.

Application

• Antimicrobial Peptide (AMP) Research: Used as a reference standard and active pharmaceutical ingredient (API) intermediate in the development of novel antibiotics targeting drug-resistant bacteria.
• Molecular Imaging Probe Development: Serves as a key precursor for synthesizing radiolabeled (e.g., with 99mTc) peptides used in SPECT imaging to localize and diagnose bacterial infections.
• Biochemical Assay Standard: Employed in in vitro assays to study peptide-membrane interactions, antimicrobial mechanisms of action, and structure-activity relationships (SAR).
• Pharmaceutical Intermediate: Acts as a building block in the solid-phase or solution-phase synthesis of full-length ubiquicidin or its analogs for preclinical and clinical studies.
• Diagnostic Kit Component: Utilized in the development and calibration of diagnostic kits and reagents designed for the specific detection of microbial pathogens.

Quality Control

Our (29-41)-Ubiquicidine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including reversed-phase HPLC for purity, mass spectrometry (MS) for identity confirmation, and amino acid analysis (AAA). Certificates of Analysis (COA) detailing purity, peptide content, and residual solvent levels are provided with every shipment. We support development under cGMP guidelines for pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. This material is hygroscopic (moisture-sensitive). Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture uptake. For long-term storage, consider under an inert atmosphere.
