The original buffer is 7% SDS- 1% BSA -0.25 M sodium phosphate pH 7.2
The reagents I use are as follows: SDS Bio Rad 161 0302, BSA Sigma A-7906,
di-sodium phosphate from Fluka 71643. The reference is PNAS (1984) :81,
The buffer is stable at RT. Blots can be washed either in 50 mM sodium phosphate
-1% SDS or in SSC solutions after hybridizations. For DIG and biotin blots
I use Boehringer blocking reagent instead of BSA.
