1975年以来许多学者都认为成熟的T淋巴细胞多具有在酸性环境能水介α-醋酸萘脂的非特异性脂酶。这类酶又特称为酸性α-醋酸萘脂酶(acid α-naphthyl acetate esterase ANAE)。大多数B淋巴细胞则为ANAE阴性。故ANAE可作为T淋巴细胞的标志。一些人注意到淋巴细胞的ANAE反应产物呈两种形态:或为一个到数个孤立
Since 1975, many scholars believe that mature T lymphocytes are more non-specific lipase capable of hydrolysing α-acetate naphthol in acidic environment. This type of enzyme is also called acid alpha-naphthyl acetate esterase ANAE. Most B lymphocytes are ANAE negative. Therefore, ANAE can be used as a sign of T lymphocytes. Some people noticed that the lymphocyte ANAE reaction product appeared in two forms: one or several isolated
