 AB    A sensitive and selective method for the determination of dextran
       sulfate in rat serum has been developed. The analysis is suitable for
       quantitation of the drug and for monitoring molecular mass changes
       occurring during biotransformation. Dextran sulfate is resolved from
       higher molecular mass serum components by high-performance aqueous
       size-exclusion chromatography. The method has been validated for the
       direct injection of serum. Sensitive detection is achieved by
       post-column reaction of the polyanionic drug with the dye
       1,9-dimethylmethylene blue. Components of serum which inhibit complex
       formation are separated chromatographically from dextran sulfate.
       Absorbance of the metachromatic complex is monitored at 525 nm.
