Probe specification

  • IGK, 2p11.2, Red
  • IGK, 2p11.2, Green

The IGK product consists of a 301kb probe, labelled in red, covering a part of the distal IGK Variable region and a green probe, covering a 606kb region telomeric to the Joining segments and the Constant segment of IGK. The green probe extends from a position that is telomeric to the D2S2216 marker and continues to a position that is centromeric to the D2S2510 marker.


Probe information

Recurrent rearrangements involving the IGK (immunoglobulin kappa locus) gene at 2p11.2, with a wide range of partner genes, are seen in lymphomas and haematological malignancies.

A large number of B-cell malignancies harbour translocations involving the immunoglobulin (IG) loci. The majority of cases will show rearrangements involving the IGH gene; however, variant translocations have been described in 5-10% of B-cell neoplasms which involve either the immunoglobulin kappa (IGK) light chain locus at 2p11.2 or the immunoglobulin lambda (IGL) light chain locus at 22q111,2.

Variant translocations involving the IG light chain loci are seen in Burkitt lymphoma and multiple myeloma, with the presence of a t(2;8)(p12;q24) MYC-IGK, or t(8;22)(q24;q11) MYC-IGL3,5. In diffuse large B-cell lymphoma (DLBCL), translocations may involve the BCL6 gene via t(2;3)(p12;q27) or t(3;22)(q27;q11) translocations, or the BCL2 gene via t(2;18)(p12;q21) or t(18;22)(q21;q11) translocations6.

Sample and slide preparation

1. Sample & Slide Prep Dark Blue
  • Spot the cell sample onto a glass microscope slide. Allow to dry.
  • Immerse the slide in 2x Saline Sodium Citrate (SSC) for 2 minutes at room temperature (RT) without agitation.
  • Dehydrate in an ethanol series (70%, 85% and 100%), each for 2 minutes at RT.
  • Allow to dry.
