用Bligh和Dyer抽提法从细胞和缓冲液中分离出人中性粒细胞经酵母多糖或钙离子载体刺激后合成的血小板活化因子(PAF)。对提取物进行磷脂类的TLC分离,然后进行反相HPLC进行分子种类分离。测量所有馏分的放射性、生物活性和快原子轰击质谱。虽然放射性示踪剂PAF可以分离成三种分子种类,但PAF生物活性洗脱为单一组分,其特征在于1-O-十六烷基-2-乙酰基-甘油-3-磷酸胆碱。PAF的分子物种的异质性,在响应刺激的缺乏意味着更高程度的控制生物合成比以前怀疑。
Platelet activating factor (PAF)★synthesized by human neutrophils challenged by opsonized zymosan or calcium ionophore was isolated from cells and buffer using Bligh and Dyer extraction following the addition of tracer amounts of tritiated-PAF. The extract was subjected to TLC separation of phospholipid classes, followed by reverse phase HPLC for molecular species separation. All fractions were measured for radioactivity, biological activity and fast atom bombardment mass spectrometry. While the radioactive tracer PAF could be separated into three molecular species, PAF biological activity eluted as a single component which was characterized as 1-O-hexadecyl-2-acetyl-glycero-3-phosphocholine. The lack of molecular species heterogeneity of PAF produced in response to stimuli implies a higher degree of control of biosynthesis than previously suspected.
