This is my assignment.
A pure protein was subjected to N-terminal analysis using c14-phenyl isothiocyanate,specific activity 120ci/mole.Reaction of the reagent with 2.3microgram of protein produced 12,300 cpm PTH-met and 8200 cpm PTH-val with a 90% counting efficiency.Calculate molecular weight of protein and subunit composition?
I got an answer(1.40x10e6)
I have no idea if this is rite answer.let me know if anyone can help me with this
