采用磁性聚丙烯酰胺颗粒包埋活性炭的地高辛放射免疫分析。

Clin Chim Acta. 1978 Jun 15;86(3):353-6. doi: 10.1016/0009-8981(78)90393-5.

Charcoal and magnetisable ferric oxide were entrapped in a polyacrylamide gel and, after lyophilisation and micronisation, empolyed for the uptake of free antigen in a radioimmunoassay for digoxin. The results obtained were similar to those using a conventional charcoal separation method.

将活性炭和可磁化的三氧化二铁包埋于聚丙烯酰胺凝胶中，冻干并微粉化后，用于地高辛放射免疫分析中游离抗原的摄取。所获得的结果与使用传统活性炭分离方法的结果相似。
