From the re-emerging role of HLA-DQ in transplantation medicine to the growing attention in autoimmune conditions and disease susceptibility

We provide a matrix of highly representative HLA-DQ alleles that help to drive novel research to prevent transplant rejection and to contribute to more insight into CD4+ T cell responses. Learn more about HLA.

Frequently Asked Questions

What is the molecular weight of a sHLA Class II molecule?

Soluble HLA Class II glycosylated protein complexes are 61 kDa in size consisting of a 27 kDa beta chain and a 26 kDa alpha chain with a small size peptide (15 to 24mer) in the groove.

What is a DQ matrix?

Because of the high polymorphism associated with DQ molecules, we have formulated a combinatorial matrix consisting of a selection of alpha (DQA1) and beta (DQB1) chains. The DQ matrix consists of 13 DQA molecules that pair with 17 DQB molecules resulting in a combinatorial matrix of 221 possible combinations.

What does a sHLA Class II molecule look like?

Structurally, sHLA Class II proteins are heterodimeric glycoproteins consisting of an alpha chain, a beta chain and an endogenously loaded peptide they present forming a trimeric complex.
