Immunogenetics and Antibody Detection

Genotyping of immune response genes and characterisation of antibodies to self and non-self

Discuss your project

Human Leukocyte Antigen (HLA) is not the only immune response gene for which variants have been identified, and where variants can impact the immune response either directly or through sensitisation to non-self (allogeneic) variants.

Killer Cell Immunoglobulin-Like Receptor (KIR)

KIR genetics is complex: different KIR genes may or may not be present, giving rise to genetic diversity.  Like HLA, polymorphic variants of the KIR genes also exist; different alleles may exhibit functional differences.

We perform PCR-RSSO presence/absence testing for the following Killer Cell Immunoglobulin-Like Receptor (KIR) genes:

Activating KIR genes

  • KIR2DS1, KIR2DS2, KIR2DS3, KIR2DS5, KIR3DS1, KIR2DS4*

Inhibitory KIR genes

  • KIR2DL1, KIR2DL2, KIR2DL3, KIR2DL4, KIR2DL5*, KIR3DL1, KIR3DL2, KIR3DL3

Pseudogenes

  • KIR2DP1, KIR3DP1

* Including non-expressed null alleles

Antibody Detection

We use Luminex xMAP® technology to detect antibodies (presence/absence testing) and are able to further characterise antigen specificity as required.

We use the most comprehensive antigen panels available.

Our assays are able to detect and characterise human IgG antibodies directed against:

  • HLA Class I (HLA-A, HLA-B, HLA-C) and Class II (HLA-DRB1, HLA-DRB3, HLA-DRB4, HLA-DRB5, HLA-DQA1, HLA-DQB1, HLA-DPA1 and HLA-DPB1).
  • Human Neutrophil Antigens (HNA):  HNA-1a, HNA-1b, HNA-1c, HNA-2, HNA-3a, HNA-3b, HNA-4a, HNA-5a and HNA-5b.
  • MHC Class I Related Chain A (MICA).
  • A variety of putative autoantibodies.

Whether you require antibody detection and specification in the sera of research subjects or the supernatant of cell lines, our team are happy to provide advice when planning your study or interpreting your results.
