I have a question on the nature of "radiolyis" of P-32 hybridiazation
probes. When people talk about probes breaking down due to radiolysis, is
that occuring because of
1) decay of the incorporated P-32 to S-32 results in breakage of the
phosphodiester bond in some way
2) the action of the emitted beta particals in the sample results in
fragmentation of the probe
3) a combination of the above two processes.
I'm mostly curious (but also have a more practical matter in mind about a
failed hybridization) and haven't really found the answer anywhere else.
