From investigating HLA-antibody interactions in transplantation to antigen-specific CD8+ cytotoxic T cells in disease states

We provide a suite of highly representative, functionally intact HLA-B alleles with broad population coverage known as the most diverse genetic markers used by the body to accept or reject transplants. Learn more about HLA.

Frequently Asked Questions

How does a sHLA Class I molecule look like?

Structurally, sHLA Class I proteins consist of a heavy chain, a light chain (b2m) and the peptide they present forming a trimeric complex. Various sHLA alleles have an added purification tag (VLDL) at the carboxy end of the α3 domain.

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

Soluble HLA Class I glycosylated protein complexes are 47 kDa in size consisting of a 33 kDa heavy chain, an 11 kDa beta-2-microglobulin light chain and a small size peptide (8 to 11mer) in the groove.

Can I freeze sHLA molecules?

We do not recommend freezing sHLA molecules as loss of activity up to 20% can occur during a freeze-thaw cycle.
