TE buffer. TE buffer is a commonly used buffer solution in molecular biology, especially in procedures involving DNA, cDNA or RNA. TE is derived from its components: Tris, a common pH buffer, and EDTA, a molecule that chelates cations like Mg2+. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.
The TR is the time between consecutive 90 degree RF pulse. The TE is the time between the initial 90 degree RF pulse and the echo. The TR, matrix size and NEX are the only parameters that affect scan time. Increasing any one of these parameters increases the minimum scan time.
