Description			Biocompatible, antibacterial and environmentally friendly polyelectrolyte with a variety of applications including water treatment, chromatography, additives for cosmetics, textile treatment for antimicrobial activity, novel fibers for textiles, photographic papers, biodegradable films, biomedical devices, and microcapsule implants for controlled release in drug delivery. May be used as a flocculant in protein precipitation and as encapsulating agent and aqueous thickener. Forms gels with multivalent anions. Gives clear solutions that dry to strong, clear films. Source: Animal Origin Molecular Weight: Medium (190-310 kDa based on viscosity) Solubility: Soluble in dilute acidic aqueous solvents Hazy mixture results when prepared at 10mg/ml in 1M acetic acid (extensive sonication may bre required to fully suspend and dissolve the material) Insoluble in water and organic solvents. Viscosity: 200-800 cP (c=1%; 1% Acetic Acid) Deacetylation: 75-85% Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
