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......阅读全文

Rf值-(retention-factor)

Rf值 (retention factor)对于确定的固定相,混合物样品中不同的化合物在层析板上爬升的速度不同,这是由于它们对于固定相的吸附能力不同,对于洗脱剂的溶解能力也不同。改变不同的洗脱溶剂,或用不同溶剂配成混合洗脱剂,化合物的分离效果可自行调节。组分在板上的分离情况一般用比移值(Rf)的大小
