DETAILS

Description (English)

Other Notes
Inhibitor of haemoprotein enzymes, catalase1; Bacteriostatic in storage solutions. Avoidance of bacterial contamination during RPC-5 column chromatography of DNA fragments2; Preservation of milk samples3; Inhibits gram negative flora, hence included in culture media for the selective isolation of Streptococci and Staphylococci4.
