Abstract
A one-step immunospecific affinity chromatographic method for purification of mouse alpha-fetoprotein (AFP) directly from amniotic fluid is described. The procedure employed a rabbit anti-AFP immunoglobulin-G entrapped in a polyacrylamide gel matrix prepared as a gel slurry. The presence of impurities could not be demonstrated in the eluted fraction and the recovery of AFP was approximately 26%. Sufficient quantities of AFP were readily purified for raising antibodies and for purity studies.
摘要
本文描述了一种直接从羊水纯化小鼠甲胎蛋白（AFP）的一步免疫特异性亲和色谱法。该方法采用包埋于聚丙烯酰胺凝胶基质（制成凝胶悬液）中的兔抗AFP免疫球蛋白G。洗脱组分中未检测到杂质，AFP的回收率约为26%。可轻松纯化出足够量的AFP用于制备抗体和纯度研究。
