Rabbit anti-Toxic Shock Syndrome Toxin polyclonal antibody for DID. Suitable for use in DID (Ouchterlony). Each laboratory should determine an optimum working titer for use in its particular application. Other applications have not been tested but use in such assays should not necessarily be excluded.Toxic Shock Syndrome Toxin (TSST) is a superantigen with a size of 22KDa produced by somewhere between 5% and 25% of Staphylococcus aureus isolates. It causes toxic shock syndrome by stimulating the release of large amounts of interleukin-1, interleukin-2 and tumour necrosis factor. In general, the toxin is not produced by bacteria growing in the blood; rather, it is produced at the local site of an infection, and then enters the blood stream.
