Agencourt RNAdvance Blood kit

[bethedelblute]

Hi, I'm using a blood RNA kit from Agencourt that uses 2 binding buffers, the first to bind to the magnetic beads and a second to rebind after the DNase reaction. My problem is that the second buffer, called Bind 2 in the kit, is supposed to be kept at 4 degrees but I (stupidly!) left it out for about 2 days at room temperature. Can I still use this buffer or is there no way around buying a new expensive bottle of this solution?

Thanks!!
