Description

Heme C CAS NO 26598-29-8 is a specific heme derivative, a metalloporphyrin complex where the heme group is covalently attached to a protein via thioether bonds to cysteine residues. This compound is essential for its role as the prosthetic group in c-type cytochromes, which are critical for electron transfer in biological energy production. It is a vital biochemical reagent for researchers and manufacturers in the life sciences, pharmaceuticals, and diagnostic sectors, enabling studies in cellular respiration, enzyme function, and the development of bioanalytical assays.

Application

• Biochemical Research: As a critical standard and reagent in studies of mitochondrial function, electron transport chains, and cytochrome c biochemistry.
• Pharmaceutical Development: Used in the research and production of compounds targeting cellular metabolism and as a component in specialized drug delivery systems.
• Diagnostic Reagents: Serves as a key component in the formulation of clinical diagnostic kits, particularly those measuring enzymatic activities related to cellular health.
• Enzyme Cofactor Studies: Essential for in vitro reconstitution experiments to study the activity and mechanism of heme-dependent enzymes and peroxidases.
• Nutritional & Cosmetic Research: Investigated for its potential bioactive properties in specialized nutritional supplements and high-end cosmetic formulations.
• Reference Standard: Used as a high-purity calibrant in analytical laboratories for HPLC, MS, or spectroscopic quantification of heme-related compounds.

Quality Control

Our Heme C is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity suitable for research and development. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and relevant spectroscopic data. We support compliance with various research and quality standards, and specifications can be tailored upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) for long-term stability, as the compound is light-sensitive and easily oxidized. For short-term use, keep desiccated at 2-8°C. Allow the sealed container to reach room temperature before opening to minimize moisture condensation.
