Antinuclear antibody. In immunofluorescence, the level of autoantibodies is reported as a titre. This is the highest dilution of the serum at which autoantibodies are still detectable. Positive autoantibody titres at a dilution equal to or greater than 1: 160 are usually considered as clinically significant.Name: Smith extractable nuclear AbRibonucleoprotein extractable nuclear IgG Ab [Titer in Serum by Immunoassay System: Ser.

An extractable nuclear antigen (ENA) panel detects the presence of autoantibodies in the blood that react with proteins in the cell nucleus. These proteins are known as extractable because they can be removed from cell nuclei using saline and represent six main proteins (Ro, La, Sm, RNP, Scl70 and Jo1).

Ribonucleoprotein antibodies: frequency and clinical significance in systemic lupus erythematosus, scleroderma, and Testing for autoantibodies to extractable nuclear antigens (ENAs) provides a cogent example. Interpretation of the clinical significance and role of these antibodies in the diagnosis and management of CTDs is based on information gained by using gelbased techniques, such as double immunodiffusion (DID) and (CIEP) ( 11 ). ribonucleoprotein extractable nuclear ab serum quantitative AntiENA (Antibodies to Extractable Nuclear Antigens) AntiLa AntiRibonuclear Protein AntiRNP AntiRo AntiSjogren's Syndrome AntiSm (Smith) AntiSmith (SM) Antigen AntiSSA (AntiSjogren's Syndrome A) AntiSSB (AntiSjogren's Syndrome B) AntiU(1)RNP Antibodies to Extractable Nuclear

Nov 21, 2014 Description. AntiRNP antibodies are directed against the U1 particle of an extractable nuclear antigen (ENA) named ribonucleoprotein, [ which is made up of a complex of proteins and a small nuclear RNA named U1. [ Ribonucleoprotein is part of the splicosome and also includes Smith (Sm) antigen, which is the target of the antiSmith antibody and is frequently positive in SLE. ribonucleoprotein extractable nuclear ab serum quantitative Ribonucleoprotein Antibody. The Sm and nuclear ribonucleoprotein (RNP) antigens are a particulate complex composed of small nuclear RNAs (URNAs) and proteins. This complex has also been referred to as extractable nuclear antigens (ENA), since it is soluble in saline. Autoantibodies to these antigens occur in systemic lupus erythematosis (Background Information) Extractable nuclear antigen (ENA) antibodies are a group of autoantibodies that target proteins in a cells nucleus. Antibodies, or soluble immunoglobulins, are bodily defense proteins that protect against foreign invaders, such as bacteria, viruses, and other microorganisms. Extractable Nuclear Antigen Antibodies (RNP, Smith, SSA 52, SSA 60, and SSB) Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube.
