I waqnt to know if anyone has tried +4 C P33 for sequencing. If so, how stable is the isotope i.e. does it degrade faster than the normal P33? In other words, is there any difference between the decay chart of the +4 p33 and the normal P33? Thank you all for your replies (in advance) Fariborz Yazdani email: fari at evol.biology.mcmaster.ca
