A ubiquitous nonimmunoglobulin molecule that binds p-azobenzenearsonate (ABA) has been detected in the cytoplasm of several murine cell lines, including T cell hybridomas as well as in normal liver and spleen. Similar to many recently described antigen-specific T cell factors, this ABA-binding protein has a 62,000 mol wt, and, when analyzed by direct binding, the molecule reacts with several different rabbit anti-idiotypic antisera specific to the ABA system. The presence of this antigen-specific, "idiotype positive" molecule in many different cells indicates that it is not an important immunoregulatory molecule.
在几种小鼠细胞系的细胞质中,包括T细胞杂交瘤以及正常肝脏和脾脏中,检测到一种能结合对氨基苯砷酸(ABA)的普遍存在的非免疫球蛋白分子。与许多最近描述的抗原特异性T细胞因子相似,这种ABA结合蛋白的分子量为62,000道尔顿,通过直接结合分析,该分子能与几种针对ABA系统的不同兔抗独特型抗血清发生反应。这种抗原特异性的“独特型阳性”分子在许多不同细胞中的存在表明它不是一种重要的免疫调节分子。
