$0.35. Together these enzymes will remove left over primers, ssDNA and will inactivate excess dNTPs by dephosphorylation. Solid phase extraction (SPE) is a sample preparation technique often used by chromatographers prior to analysis. The software first divides the input sequence into approximately equal-temperature (Equi-T m) or equal-length fragments (Equi-space) using markers based on the user-specified melting temperature.The positions of the markers are iteratively shifted to globally minimize the deviation in melting temperature among the fragments (T m Equilibrate).
