Protein Phosphorylation & phosphatase

[Cynthia Bolognese]

I'm looking for advice on which acid phosphatase from Sigma to purchase.  
I want to treat my protein with phosphatase to determine whether or not 
it is phosphorylated. I just want something quick that will give me a 
yes or a no. Then I can plan more detailed exps. I have a ref that uses 
acid phosphatase from Sigma, but low and behold, Sigma offers 7 
different types! What type should I order? Please email me at the 
address listed. Any advice or refs will be appreciated, thanks in 
advance!
