Research Fields

Incidence of genomic aberrations Multiple Myeloma (MM) and Monoclonal Gammopathy of Undetermined Significance (MGUS). Analysis by fluorescence in-situ hybridization (FISH) with comprehensive probe sets for detection of genetic imbalances involving chromosome bands 1p22, 1q21, 6q21, 8p11, 9q34, 11q25, 13q14, 17p13 and 22q11 as well as for detection of myeloma-specific translocations.

Development of automated high-resolution genotyping through microarray based matrix-CGH.

Evaluation of genomic aberrations as prognostic markers within multicenter treatment trials of the German Multiple Myeloma Study Group (DSMM)

Development of plasma cell tissue arrays for protein analyzes using immunohisto-chemistry


  • Isolation of tumor cells by ficoll gradient and immunomagnetic cell sorting
  • Fluorescence in-situ hybridization (FISH), also in combination with immunostaining
  • DNA and RNA preparation of cells and tissues
  • DNA sequencing, sequence analysis cloning and preparation of various vector systems (plasmids, cosmids, BAC, PAC, YAC)
  • Metaphase-based and array-based comparative genomic hybridization (CGH)
