The STR profile of these cell lines match that of its parental cell line - ECACC catalog number 86012804.
This product is a panel of eleven (11) genetically modified cell lines targeting MHC Class I HLA molecules in an A549 lung carcinoma parental cell line background. The full HLA panel consists of a Beta-2 microglobulin (β2M) knockout cell line and an additional ten (10) monoallelic HLA expression cell lines.
CompoZr® Zinc Finger Nuclease (ZFN) technology was used to generate the β2M knockout cell line, which does not express endogenous cell surface MHC Class I HLA molecules (HLA-A or HLA-B) as measured by fluorescence-activated cell sorting (FACS).
MISSION® lentivirus was used to generate the ten (10) monoallelic HLA cell lines, which express individual HLA-A or HLA-B subtypes on the cell surface via a β2M:HLA fusion protein as described in Nature Biotechnology 35, 765-772, (2017) and as demonstrated via FACS analysis.
Derived from a 58 year old Caucasian male. The cells can synthesise lecithin utilising the cytidine diphosphocholine pathway. Occasional cells may also contain inclusion bodies although they are not known to carry any human pathogen.
Unlike wild type A549 cells, which express multiple HLA subtypes, the A549 HLA panel cell lines express individual MHC Class I HLA subtypes. These monoallelic HLA cell lines can be used to study peptide binding and presentation in the context of individual HLA subtypes. The panel can also be used to develop cell-based assays to evaluate candidate cancer immunotherapies and identify tumor-specific neoantigens.
