    • Long double-stranded DNA molecules were separated in microfabricated hexagonal arrays in less than 1 min, several orders of magnitude faster than by using conventional technology. DNA samples were first concentrated at the entrance to the array in a thin band by entropic focusing. They were then separated by pulsed field electrophoresis. T4 (168.9 kbp) and λ (48.5 kbp) DNAs could be resolved into two clearly separated bands in ∼10 s in these experiments. This corresponds to a mass resolution of 6% in 11 min in a 1-cm-long array.

  • Antibody response to the human stress protein BiP in rheumatoid arthritis
  • 2004
  • Ingår i: Rheumatology. - : Oxford University Press. - 1462-0324 .- 1462-0332 .- 1460-2172. ; 43:10, s. 1283-1287

    • Objectives. The human stress protein BiP (immunoglobulin binding protein) has been implicated in the pathogenesis of rheumatoid arthritis (RA) since BiP was found to stimulate synovial T-cell proliferation and anti-BiP antibodies are present in the serum of RA patients. The aim of this study was the development of a rapid and reproducible enzyme-linked immunosorbent assay (ELISA) to determine the specificity and sensitivity of anti-BiP antibodies in RA.Methods. An ELISA was developed that detected antibodies to BiP. The prevalence of anti-BiP antibodies was determined in sera from patients with early and established RA, sera antedating the onset of RA and sera from patients with other inflammatory and autoimmune diseases and healthy controls.Results. We have confirmed the increased prevalence of antibodies to BiP in the sera of a large cohort of patients with established RA (specificity 71% and sensitivity 73%) and early RA (specificity 65% and sensitivity 66%). In pre-disease sera, median 2.5 yr (interquartile range 1.1–4.7) before symptoms of joint disease, the sensitivity for anti-BiP antibodies was 45% and the specificity was 65% for the development of RA.Conclusion. Antibodies to BiP are found in the sera of patients with RA and in sera antedating the onset of RA.
