Inhloso:

I-4- hydroxyethyl piperazine i-ethyl sulfonic acid iyi-buffer yezinto eziphilayo; Ukusabela kokuhlukaniswa nokuhlaziywa kwe-buffer yengxenye ye-RNA, i-buffer, i-hybridization buffer kusengaphambili; Isetshenziselwa ukumaka i-RNA ne-T4RNA ligase 3'-terminal; Isetshenziswa kwikhithi yokuxilonga ye-biochemical, ikhithi yokukhipha i-DNA/RNA kanye nama-PCR diagnostic kits. Kumaseli angathelelekile asebenza. Luhlobo lwe-buffer ye-hydrogen ion, lungalawula ububanzi benani le-pH le-constant isikhathi eside. Sebenzisa ukuhlushwa kokugcina kwe-10-50 tendency ye-L, i-general culture medium equkethe i-20 tendency LHEPES buffering capacity ingafinyelelwa.
