My last cop forged material in cell (9)

I believe the answer is:

cytoplasm

'material in cell' is the definition.
(I've seen this before)

'my last cop forged' is the wordplay.
'forged' indicates an anagram.
'my'+'last'+'cop'='mylastcop'
'mylastcop' with letters rearranged gives 'CYTOPLASM'.

(Another definition for cytoplasm that I've seen is " Material in cell".)

I've seen this clue in The Times.
