X-linked hypogammaglobulinaemia (XLA) belongs to the primary immunodeficiencies (PID). Affected patients do not generate mature B cells and develop serious and even fatal infections if not treated. XLA is very rare (1:100,000 in male newborn). Detection of low or even missing Kappa-deleting Recombination Excision Circles (KRECs) is an indication for the presence of XLA.

1 Vial purple cap 96 reactions KREC (lyophilized)
1 Vial black cap Positive Control (32,000 copies, lyophilized)

Additional Reagents required

LightCycler® Multiplex DNA Master
or LightCycler® 480 Probes Master

An about 100 bp long fragment generated from Kappa-deleting Recombination Excision Circles is amplified with specific primers and detected with a LC610 labeled hydrolysis probe.

This assay must be combined with an extraction control, for example MSTN 66-0905-96, Cat. No. 07 225 253 001 (660 label) or 58-0905-96, Cat No. 07 559 968 001 (580 label). This assay can be combined with TREC 53-0621-96, Cat. No. 07 093 861 001(FAM label).

Specification
This assay detects 10 genome equivalent copies or less per reaction (plasmid DNA dilution).

Sample Material and Extraction
Typical specimen are newborn blood. See ModularDx Document Extraction Protocols.
