Frequently Asked Questions

What is a leucine zipper?

The leucine zipper is a common three-dimensional structural motif inserted into sHLA class II proteins that have enhanced binding capabilities displaying an alpha helix with periodic repetition of leucine residues that facilitate dimerization of the alpha and beta chain within sHLA molecules.

What is a preferable antibody to be used with sHLA DR?

We recommend the usage of the DR antibody L243 as it recognizes all sHLA-DR molecules in our catalog.

What is the difference between HLA class I and II?

HLA Class I glycoproteins are present on the surface of all nucleated cells. Class II glycoproteins are only present on specialized antigen-presenting cells (APCs), including macrophages that engulf foreign particles such as bacteria, dendritic cells that present antigens to T cells, and B cells that produce antibodies.
