ObjectivesImmunofluorescence assay (IFA) has been the standard method for antinuclear antibodies (ANA). To simplify and standardize the ANA test, generic ANA solid phase enzyme immunoassay has been promoted. The objective of the present work has been to study the relationship with IFA and the ...
ANA 的 IFA 阳性表明存在针对各种核抗原(DNA、组蛋白、非组蛋白、核抗原等)或细胞质抗原的自身抗体 7,8。应通过检测抗 ENA、抗 dsDNA 和抗 CENP-B 自身抗体进一步研究 ANA 的显着高滴度阳性。 ANA 和抗 ENA、抗 dsDNA 和/或抗 CENP 的一项或多项特异性检测呈阳性高度提示系统性自身免疫性疾病:系统性红斑...
Autoimmune IFA Products ANA Test Systems AESKU.BION - ANA Test SystemsAntinuclear antibodies (ANAs) are a group of autoantibodies characterized by specificity for numerous antigenic determinants of cell nuclei. ANAs have been proven to be very useful as disease markers, primarily for diagnostic ...
Assays for anti-nuclear antibodies (ANA) have been introduced in the second half of the previous century, first on rodent tissue as substrate and next on the human laryngeal epidermoid carcinoma HEp-2 cell line [1]. The HEp-2 indirect immunofluorescence assay (IFA) has appeared of added value...
The PolyTiter immunofluorescent titration system (PolyTiter system), an attachment for conventional fluorescent microscopes, facilitates immunofluorescent antinuclear antibody (IFA-ANA) testing by using calibrated light attenuation to determine the semiquantitative endpoint dilution or titer of ANA-positive spe...
Detection of Antinuclear Antibodies in Canine Serum by Immunoperoxidase in MDCK and Indirect Immunofluorescence in HEp2 Cells Antinuclear antibodies are found in animals suffering from Systemic Lupus Erythematosus (SLE) and some other diseases, their presence in the blood is deter...

Autoimmune Diseasecomputer-assistedinterpretationThe assessment of antinuclear antibodies (ANA) by indirect immunofluorescence (IFA) allows detection of >50 characteristic autoantibodies, making it a highly sensitive method and screening test. The semiquantitative method is based on the identification of ...
The antinuclear antibody (ANA) test has high sensitivity in diagnosing and classifying systemic lupus erythematosus (SLE).#To describe the immunological pattern of SLE patients through investigating specific antinuclear autoantibodies by enzyme dot immunoassay and studying their frequency in both positive ...
