Abstract
The phyletic distribution of Sm antigen in eukaryotes has been investigated by means of immuno-chemical techniques. This nuclear antigen, which is an acidic glycoprotein of about 7S with DNA binding ability, is present in all organisms examined. Such evidence suggests a very slow evolutionary rate for at least the antigenic determinant(s) of the Sm antigen.
摘要
通过免疫化学技术研究了Sm抗原在真核生物中的系统分布。这种核抗原是一种约7S的酸性糖蛋白，具有DNA结合能力，在所检测的所有生物体中都存在。这些证据表明，至少Sm抗原的抗原决定簇的进化速率非常缓慢。
