1*buffer, 40 mM Tris-HCl (pH 8.0), 2.5mM (max-10) MgSO4, 1mM (max-10) CaCl2

Dear Yu deshui,

Thanks for your kind reply ...

Is this buffer is a collection of all these chemicals (so I have to prepare myself) or there is a commercially available buffer that merges these chemicals.. If the later is ok., please let me know the commercial name and details if available

Thanks in advance

Thermo Fisher is ok. AM8170G, Ambion ® DNase I (am2222, am2224) and recombinant DNase I (am2235) enzyme attached buffers.
