Description

Cuprolinic Blue is a specialized, high-purity chemical compound primarily used as a sensitive and selective staining reagent for the detection of proteins and glycoproteins in analytical biochemistry. Its core value lies in its ability to form stable, colored complexes, enabling precise quantification and visualization in various separation techniques. This product is essential for research and quality control laboratories in the biotechnology, pharmaceutical, and diagnostic industries that require reliable tools for protein analysis and characterization.

Application

• Protein Staining in Electrophoresis: Used for the sensitive detection of proteins, particularly glycoproteins, following polyacrylamide gel electrophoresis (PAGE).
• Glycoprotein Analysis: Selective staining of glycoproteins in complex biological mixtures due to its affinity for carbohydrate moieties.
• Diagnostic Reagent Formulation: A key component in the development of clinical diagnostic kits and assays for protein-based biomarkers.
• Biochemical Research: Employed in laboratory research for studying protein expression, purification, and post-translational modifications.
• Quality Control in Biopharmaceuticals: Used to analyze the purity and consistency of protein-based therapeutics during manufacturing processes.
• Histology and Cytology: Potential application as a specialized stain for microscopic examination of tissue and cell samples.
