Dextro-Sang

Dextro-Sang was a small biotechnology company focused on artificial blood and oxygen-carrying blood substitute products based on dextran-hemoglobin conjugates. Patent records and secondary market reports indicate the company developed hemoglobin-dextran formulations intended as blood substitutes, with evidence suggesting a veterinary-use positioning rather than an approved human therapeutic product. Publicly available information on the company is sparse, and there is no clear evidence of an approved commercial product, active late-stage clinical pipeline, or ongoing operating business. The company appears to have been an early-stage developer of hemoglobin-based oxygen carrier technology whose visible activity is now largely limited to historical patent filings and references in market research lists.
