Line 1: 0.5% milk in PBS as a blocking buffer; 
Line 2: 0.5% BSA/PBS as a blocking buffer; 
Line 3: PBS as a blocking buffer.

Ni plate coated with 2ug/ml pka (in PBS). Well 11 & 12 wells: no coating.

1,2; 3,4; 5 wells are patient serum; 
6,7,8,9,10 wells are normal human serum; 
11 well did not add the serum, 12 wells add the same serum same as well 1.

Problem: No difference between with PKA coating or without PKA coating (well 12)

seems this time the signal is very low, next time need to put substrate for 3omin, this time 20 min.
