Description

Polygalacturonosidase 28A From Dickeya Dadantii, Recombinant is a highly specific pectinase enzyme engineered for superior catalytic efficiency and purity. This recombinant form offers exceptional consistency and activity, making it a critical tool for the controlled degradation of polygalacturonic acid (pectin). It is essential for industries requiring precise modification of pectin structure, such as food processing, textile manufacturing, and biofuel research. The product is supplied as a lyophilized powder to ensure maximum stability and ease of handling.

Application

• Food & Beverage Processing: Used for juice clarification, viscosity reduction, and improving fruit mash pressability.
• Textile Industry: Employed in the eco-friendly retting and degumming of natural plant fibers like flax and hemp.
• Biofuel Production: Facilitates the pretreatment and saccharification of pectin-rich biomass for bioethanol production.
• Plant & Agricultural Research: A key reagent for studying plant cell wall structure, pathogen defense mechanisms, and fruit ripening processes.
• Diagnostic & Analytical Kits: Serves as a component in enzymatic assay kits for pectin quantification and quality control.
• Wastewater Treatment: Aids in the breakdown of pectinaceous waste from food processing plants.

Quality Control

Our recombinant enzyme is produced under stringent conditions to ensure batch-to-batch consistency and high specific activity. Each lot is subjected to rigorous purity and activity assays, including SDS-PAGE for protein homogeneity and enzymatic activity tests against standardized pectin substrates. Certificates of Analysis (COA) detailing purity, activity (U/mg), and other critical parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. The 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 short-term use, store at 2-8°C.
