Antitoxin (5)


I believe the answer is:


'antitoxin' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for serum that I've seen before include "Antitoxin derived from blood" , "Blood component containing antibodies, used in immunisation" , "Part of blood; vaccine" , "Watery part of blood" , "Muser in blood" .)

I've seen this clue in The Independent, the Penny Press and the Evening Standard.
