  • ADPRibosylationFactor

    ADP-ribosylation factors (ARFs) are 20-kDa guanine nucleotide-binding proteins, members of the Ras GTPase superfamily that were initially recognized and purified because of their ability to stimulate the ADP-ribosyltransferase activity of the cholera toxin A subunit. We now know that they are critical components of several different vesicular trafficking pathways in all eukaryotic cells and activators of specific pho......閱讀全文

    Rf值-(retention-factor)

    Rf值?(retention?factor)對于確定的固定相,混合物樣品中不同的化合物在層析板上爬升的速度不同,這是由于它們對于固定相的吸附能力不同,對于洗脫劑的溶解能力也不同。改變不同的洗脫溶劑,或用不同溶劑配成混合洗脫劑,化合物的分離效果可自行調節。組分在板上的分離情況一般用比移值(Rf)的大小
