Nucleolar staining pattern of ANAs. Until around 1975, when HEp-2 cells were introduced, animal tissue was used as the standard substrate for immunofluorescence. [11] HEp-2 cells are currently one of the most common substrates for ANA detection by immunofluorescence. [54]

Immunofluorescence pattern of SS-A and SS-B antibodies. Produced using serum from a patient on HEp-20-10 cells with a FITC conjugate. Anti-SSA autoantibodies (anti–Sjögren's-syndrome-related antigen A autoantibodies, also called anti-Ro, or similar names including anti-SSA/Ro, anti-Ro/SSA, anti–SS-A/Ro, and anti-Ro/SS-A) are a type of anti-nuclear autoantibodies that are associated with ...
HEp-2 cells provide a greater ability to differentiate patterns of ANA than animal sections, due to the large nuclei and high mitotic rate of the cell line. Upon incubation with serum containing anti-dsDNA antibodies and fluorescent labelled secondary antibodies, homogeneous staining of interphase nuclei and condensed chromosomal staining of ...
The ANA tests for the presence or absence of autoantibodies, while the ENA panel evaluates which proteins in the cell nucleus the autoantibodies recognize. The ENA panel helps diagnosis, distinguish between, and monitor the progression of autoimmune diseases and is performed with a simple blood draw.

Immunofluorescence staining pattern of anti-centromere antibodies on HEp-20-10 cells. Anti-centromere antibodies (ACAs; often styled solid, anticentromere) are autoantibodies specific to centromere and kinetochore function.
Nucleolar protein 56 is a protein that in humans is encoded by the NOP56 gene. [5] [6] Nop56p is a yeast nucleolar protein that is part of a complex with the nucleolar proteins Nop58p and fibrillarin. Nop56p is required for assembly of the 60S ribosomal subunit and is involved in pre-rRNA processing. The protein encoded by this gene is similar ...
