Cross-reactivity of commercial anti-human IgA and IgG reagents used in sandwich ELISA assays.

Dilutions: 1∶1 = 4 microg/mL; 1∶10 = 400 ng/mL; 1∶102 = 40 ng/mL; 1∶103 = 4 ng/mL; 1∶104 = 400 pg/mL; 1∶105 = 40 pg/mL. Response variability was also reported in the Table.Results are expressed in OD values.稀释比例：1∶1 对应 4 微克/毫升（μg/mL）；1∶10 对应 400 纳克/毫升（ng/mL）；1∶10² 对应 40 纳克/毫升（ng/mL）；1∶10³ 对应 4 纳克/毫升（ng/mL）；1∶10⁴ 对应 400 皮克/毫升（pg/mL）；1∶10⁵ 对应 40 皮克/毫升（pg/mL）。响应变异性亦于表格中予以记载。结果以光密度（Optical Density，OD）值表示。
