ICAP
AC-11 - Smooth nuclear envelope
Previous Nomenclature nuclear rim, nuclear membrane, membranous
Description Homogeneous staining of the nucleus with greater intensity at its outer rim and no staining at the metaphase and anaphase chromatin plates. There is a peculiar accentuation of the fluorescence at the points where adjacent cells touch each other. e.g. anti-lamin B.
Antigen Association lamins A,B,C, or lamin-associated proteins

About Clinical Relevance & List of Abbreviations

The AC-11 pattern is infrequently found in routine autoantibody testing and has been described in autoimmune-cytopenias, autoimmune liver diseases, linear scleroderma, APS, and SARD; current information on clinical associations is based mainly on case reports and small cohorts (58–60)

Antigens recognized include lamins (A, B, C) and LAP-2; specific immunoassays for these autoantibodies are currently not commercially available (58–60)
