I would like to know if 1,2% gel is good for running the genomic DNA. Can you help me?

In past I have seen that gDNA runs well on 0,8 gel (home made gel agarose) but with precast gel I haven't had the possibility of choosing the right percent of agarose.

Maria Sotirios Kaponi

Dear Vincenzo,

Dynabeads M-280 or M-270 (invitrogen, Dynal) suggest the following binding and wash buffer (B&W):

2x concentrated:

10 mM Tris-HCl (pH 7.5), 1 mM EDTA, 2M NaCl, (optional) 0.1%Tween 20.

Adding an equal volume of biotinylated DNA or RNA gives an 1x binding buffer with a concentration of 1 M NaCl.

Hoping this is a good suggestion,

Maria
