Description

Ribosomal Protein L21 is a key structural and functional component of the large ribosomal subunit, essential for protein biosynthesis. This high-purity protein is critical for fundamental research in molecular biology, structural studies, and the development of novel therapeutic strategies targeting ribosomal function. It is primarily utilized by research institutions, pharmaceutical R&D departments, and biotechnology companies engaged in proteomics, antibiotic mechanism studies, and ribosome assembly analysis.

Application

• Biochemical Research: Used as a standard or reagent in studies of ribosome structure, assembly, and function.
• Proteomics & Structural Biology: Essential for protein-protein interaction studies, crystallography, and cryo-electron microscopy to map ribosomal architecture.
• Antibiotic Mechanism Studies: Employed to investigate how certain antibiotics bind to and inhibit the bacterial ribosome.
• Enzyme & Protein Interaction Assays: Serves as a substrate or binding partner in in vitro assays to study translational fidelity and factors.
• Diagnostic Development: Potential use as a component in assays designed to detect ribosomal abnormalities or autoantibodies.
• Educational & Reference Material: Supplied to academic laboratories for teaching advanced concepts in molecular genetics and translation.

Quality Control

Our Ribosomal Protein L21 is produced and tested under stringent conditions to ensure the highest standards of purity and biological activity, suitable for sensitive research applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and functional data. We adhere to rigorous in-house quality protocols to guarantee batch-to-batch consistency and reliability.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. For optimal stability, aliquot into single-use quantities to avoid repeated freeze-thaw cycles.
