HLA Protein Shop

Now available: soluble recombinant class I and class II Human Leukocyte Antigens (HLA) from imusyn.

Our HLAs are produced in mammalian cell cultures as recombinant, truncated, soluble antigens, either in complex with β2-microglobulin (HLA class I) or as zipper-stabilized heterodimers (HLA class II). As part of our quality control, all HLA are analyzed for purity by gel electrophoresis, concentration is determined by ELISA (0.5 mg/ml) and their functionality is verified with a specific antiserum.

All proteins are for research use only (RUO).

Applications include but are not limited to: HLA sandwich ELISA, HLA direct ELISA, use as HLA control in various assays, HLA blocking assays, HLA neutralization assays, HLA competition assays, HLA bead ELISA, and in vitro B cell stimulation.
