Abstract

Monoclonal antibodies J5, VIL-A1, and BA-3, known to react with the common acute lymphoblastic leukemia antigen (CALLA) were found to specifically stain normal human polymorphonuclear neutrophils (PMN). The antigen detected on PMN had a molecular weight (95,000-110,000 mol wt) close to that of CALLA (95,000-100,000 mol wt) and thus these surface membrane antigens are likely related, if not identical. The fluorescent staining intensity of PMN is comparable to that of CALLA-positive leukemic cells and the presence of PMN in patient samples could potentially produce false-positive results in diagnosis.

摘要

已知可与常见急性淋巴细胞白血病抗原(CALLA)发生反应的单克隆抗体J5、VIL-A1和BA-3,被发现可特异性地对正常人多形核中性粒细胞(PMN)进行染色。在PMN上检测到的抗原分子量(95,000 - 110,000道尔顿)与CALLA的分子量(95,000 - 100,000道尔顿)相近,因此,即使这些表面膜抗原不完全相同,它们也可能相关。PMN的荧光染色强度与CALLA阳性白血病细胞的染色强度相当,患者样本中PMN的存在可能会在诊断中产生假阳性结果。
