Structural features of Fab fragments of rheumatoid factor IgM-RF in solution

Crystallography Reports, 2008
The structural features of the Fab fragments of monoclonal (Waldenstrom’s disease) immunoglobulin M (IgM) and rheumatoid immunoglobulin M (IgM-RF) were studied by a complex of methods, including small-angle X-ray scattering (SAXS), electron spin resonance (ESR), and mass spectrometry (MS).

Anti-CCP antibodies have more diagnostic impact than rheumatoid factor (RF) in a population tested for RF

Clinical Rheumatology, 2007
To compare the diagnostic powers of rheumatoid factor (RF) and anti-cyclic citrullinated peptide (CCP) in a population selected for its high statistical relevance, over a 6-month period, an informed consent to test for anti-CCP was obtained from 1,025 consecutive patients for whom RF was ordered at a University laboratory.

Relationship between alcohol consumption and rheumatoid factor (RF) with alcohol-induced facial flushing response

Alcohol, 2020
This study investigated the relationship between alcohol consumption with alcohol-induced facial flushing response and rheumatoid factor (RF) in adult men. The cohort comprised 1675 men who underwent a general medical check-up between July 2016 and June 2017, including 355 non-drinkers, 498 flushers, and 822 non-flushers.

Quantitative Analysis of Precursors Frequency of Rheumatoid Factor (RF) Producing Human B Cells

Scandinavian Journal of Rheumatology, 1988
Recently, a new culture system has been devised which leads to activation, proliferation and differentiation into antibody secreting cells of at least 90% of human peripheral blood B-lymphocytes. The system uses mutant EL-4 thymoma cells of mouse origin for B cell activation and T cell/macrophage supernatant as source of cytokines (L.

Prevalence of IgE rheumatoid factor (IgE RF) in mixed cryoglobulinemia and rheumatoid arthritis.

Clinical and experimental rheumatology, 1987
IgE RF was measured by ELISA assay using aggregated IgG as a solid phase immunosorbent and alkaline phosphatase-conjugated Fc epsilon-specific monoclonal and polyclonal antibodies as indicators. The presence of IgE RF was defined in this assay as binding of the conjugate greater than 2.33 SD above the mean for control sera (N = 27).

Solution structures of human immunoglobulins IgG and IgM and rheumatoid factor IgM-RF

Crystallography Reports, 2003
The low-resolution structures of human immunoglobulins M (IgM) and G (IgG) and the rheumatoid factor (IgM-RF) in solution were determined from synchrotron-radiation small-angle X-ray scattering by the method of dummy atom modeling (bead models). The structural models of IgM determined on the assumption that the molecule has a fivefold symmetry axis are

A population study of rheumatoid factor in Iceland. A 5-year follow-up of 50 women with rheumatoid factor (RF).

Annals of clinical research, 1976
The subject of this paper is a 5-year follow-up of 50 women found with Rose-Waaler Titre greater than or equal 1 : 10 or with a Acryl Fixation Titre greater than or equal 1 : 10 in a general health survey conducted in the Reykjavik area in 1968-1969. The average annual incidence of RA was 2.3 percent. Of four women who died during the follow-up period,

Antiimmunoglobulins of rheumatoid factor (RF) type in prediction of melanoma patients.

Neoplasma, 1987
It was found out the titer of antiimmunoglobulins of the rheumatoid factor (RF) type in the sera of melanoma patients can be used in prediction of the development of the patients' status. High titers of antiimmunoglobulins of the RF type, determined by the latex-fixation test (LFT), indicate an unfavorable prognosis in patients with clinical ...

Probing of the rheumatoid factor (RF) V gene repertoire in rheumatoid arthritis (RA) by hybridoma clones.

Clinical and experimental rheumatology, 1991
Twenty human monoclonal antibodies with rheumatoid factor (RF) specificity were produced from fusions using B lymphocytes derived from the synovial tissue of two patients with rheumatoid arthritis (RA) and one with the polyarticular form of juvenile rheumatoid arthritis (JRA) (1). All the 20 monoclonal antibodies were IgM.
