Anti-fibrillarin autoantibodies are useful for the diagnosis and prognosis of systemic sclerosis (SSc). Anti-fibrillarin produces a clumpy nucleolar pattern in indirect immunofluorescence assay on HEp-2 cells (HEp-2 IFA). Here we develop and validate a reliable cell-based anti-fibrillarin assay (Fibrillarin/CBA) for use in clinical diagnostic laboratories. https://www.diegojavierfares.com/quick-sale-Mariya-B-Lawn-Festival-Collection-Vol-3-Nx-Shree-Fabs-Lawn-Cotton-Pakistani-Readymade-Suits-Supplier-India-p30452-top-buy/
