In this work electrophoretic mobility as well as molecular weight of dental plaque proteins were examined. Three types of electrophoresis and three procedures for molecular weight estimation were applied. The results showed that the electrophoretic mobility of some protein fractions present in plaque corresponded to the mobility of human serum albumin, albumin, alpha 1, alpha 2, beta and gamma globulins. The molecular weight of these proteins was estimated as to be 65,000 to 900,000 daltons approximatively. Electrophoretic mobility and molecular weight of dental plaque proteins were similar to the physicochemical properties of human serum albumins, alpha 1 anti-tripsin, transferin, some of the components of complement system, to secretory IgG and to some categories of lipoproteins, all of which we have identified immunochemically in human dental plaque samples.
在这项研究中，对牙菌斑蛋白质的电泳迁移率和分子量进行了检测。应用了三种类型的电泳和三种分子量估计方法。结果表明，菌斑中存在的一些蛋白质组分的电泳迁移率与人血清白蛋白、白蛋白、α1、α2、β和γ球蛋白的迁移率相对应。这些蛋白质的分子量估计约为65,000至900,000道尔顿。牙菌斑蛋白质的电泳迁移率和分子量与人血清白蛋白、α1抗胰蛋白酶、转铁蛋白、补体系统的一些成分、分泌型IgG以及某些类别的脂蛋白的物理化学性质相似，所有这些我们都已在人类牙菌斑样本中通过免疫化学方法鉴定出来。
