[Drosophila] about Dopa decarboxylase enzyme asssay

[Fei Li]

Hi, all,

Is there anybody have protocol in hand about Dopa decarboxylase enzyme 
asssay? I can not access the full text of the paper who describe the 
assay method. The paper is :

Sherald, A.F., Sparrow, J.C. & Wright, T.R.F. (1973) A 
spectrophotometric assay for /Drosophila/ Dopa decarboxylase. /Anal. 
Biochem./ *56*, 300–305..

I believe there could be some modification 30 years late. But 
unfortunately, I did not any paper give detail procedure. Most papers on 
DDC just cited above references.

Thanks for your help.

Fei
