Scharlau Tryptic Soy Agar (TSA), Eur. Pharm.

Scharlau Tryptic Soy Agar provides a general-purpose solid medium containing peptones of animal and plant origin. TSA is also known as casein soybean digest agar, a useful name when comparing laboratory methods and purchasing specifications. The manufacturer links this medium to the Pharmacopoeial Harmonised Method and cites ISO 9308-1 and ISO 22717. Its broad culture purpose makes it relevant where a method calls for this agar rather than a selective medium. Reference 01-200-500 identifies the dehydrated TSA presentation; the sheep-blood and neutraliser-containing preparations listed elsewhere on the family page have separate article references. The selected article is supplied as 500 g of dehydrated medium in a vacuum-wrapped flask. Prepare it and perform incubation, reading and quality-control checks according to the applicable laboratory procedure and manufacturer instructions.
