本文报导了用一种特异性抗脑α_2糖蛋白的抗血清(抗NSA_3抗血清)以免疫萤光技术研究各种神经系统肿瘤.存在于正常脑组织的脑α_2糖蛋白曾于1972年被作者用双向免疫扩散技术在星形细胞瘤中发现(4/12).1978年作者发现此种被命名为NSA_3的神经特异性抗原与正常的、新生物的或反应性间质所具有糖蛋白有抗原的同一性.但是作者发现它具有一种仅能用免疫萤光技术测出的神经特异性抗原决定
This article reports the use of a specific anti-brain alpha 2 glycoprotein antiserum (anti-NSA 3 antiserum) to immunofluoresce study various neurological tumors. Brain alpha 2 glycoproteins present in normal brain tissue were used in 1972. Discovered in astrocytoma using a bidirectional immunodiffusion technique (4/12). In 1978, the authors discovered that this nerve-specific antigen named NSA_3 had a glycoprotein with normal, neobiological or reactive mesenchyme. The identity of the antigen. But the authors found that it has a nerve-specific antigen that can only be measured by immunofluorescence.
