Description

Sodium Thiosulfate Plant Cell Culture is a high-purity inorganic salt specifically processed for use in sensitive biological and biopharmaceutical applications. This compound is critical for its role as a reducing agent and sulfur source, directly impacting cell viability and protein expression in controlled culture systems. It is an essential reagent for researchers and manufacturers in the biotechnology, pharmaceutical, and advanced life science sectors who require consistent, ultra-pure components for mammalian and plant cell culture media.

Application

• Cell Culture Media Supplement: Used as a defined sulfur source and reducing agent in serum-free and chemically defined media formulations for mammalian and plant cell cultures.
• Biopharmaceutical Production: Supports the growth of cells used in the production of monoclonal antibodies, vaccines, and recombinant proteins by maintaining redox balance.
• Tissue Engineering: Incorporated into scaffolds and growth matrices to promote cell attachment and proliferation under in vitro conditions.
• Cytotoxicity Assay Neutralization: Acts as a quenching agent for chlorine-based disinfectants or certain cytotoxic compounds in cell-based assay validation.
• Photographic Fixer in Research Labs: Serves as a component in fixing solutions for histological and microbiological staining procedures.
• Analytical Chemistry Standard: Employed as a titrant in iodometric titrations for quantitative analysis within quality control laboratories.

Quality Control

Our Sodium Thiosulfate Plant Cell Culture is manufactured under strict quality systems to meet the exacting standards of life science research and GMP-aligned production. Each batch is tested to ensure it meets stringent specifications for purity, endotoxin levels, and bioburden. A comprehensive Certificate of Analysis (COA) is provided, detailing results for identity, assay, and critical impurities. We support compliance with relevant pharmacopeial guidelines (e.g., USP, EP) for ancillary materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the original container is sealed after each use to prevent absorption of atmospheric moisture which can lead to caking or degradation.
