The PureLink Expi Endotoxin-Free Buffer Set provides the same buffers included in the PureLink Expi Endotoxin-Free plasmid purification kits, made available separately here for those applications that would benefit from additional buffers. The Buffer Set includes all buffers and endotoxin-free components needed to enable 30 Maxi, 4 Mega, or 2 Giga PureLink Expi Endotoxin-Free plasmid purifications. Specifically, the buffer set includes RNAse A, resuspension buffer (R3), lysis buffer (L7), precipitation buffer (N3), equilibration buffer (EQ1), wash buffer (W8), elution buffer (E4), TE buffer (TE), endotoxin removal buffer, lysis indicator, and endotoxin-free water.
