| 摘要 |
Provided herein are antibodies for determining the concentration of anti-dsDNA and anti-chromatin antibodies in biological samples. In some embodiments, the presently described antibodies are single chain antibodies (e.g., scFv) that specifically bind double-stranded DNA (dsDNA) and chromatin. In some embodiments, the presently described antibodies are chimeric, and specifically bind double-stranded DNA (dsDNA) and chromatin. Such antibodies are referred to as chimeric anti-dsDNA/chromatin antibodies. Ln some embodiments, at least part of the constant region of the chimeric antibody is derived from a human antibody, e.g., a part of the constant region specifically recognized by a secondary antibody, Protein A, Protein G, or Protein A/G. In some embodiments, the constant region is derived from a human antibody. |
