UV safe TAE ?

[Rico Laage]

dear colleagues

I read in an add about UV safe TAE-buffer for DNA-gels, they said, that by 
adding UV-protective chemicals to their buffer they could increase their 
cloning efficiency about  200X  !!!!
I can`t believe this number but I would like to know if anybody out there ever 
tried this buffer or has any suggestions about it-
What chemicals are used for UV-protection (e.g. in sunblockers) ?
