used to analyze the cell surface expression of HLA-A2 and HLA-A, HLA-B,
and HLA-C: PE-conjugated antihuman HLA-A2 (clone BB7.2, BioLegend
343306 San Diego, CA), PE-conjugated antihuman HLA-A, HAL-B, and HLA-C
(clone W6/32, BioLegend 311406, San Diego, CA), and Human TruStain
FcX block (BioLegend B247182, San Diego, CA).
The data were
acquired using a BDLSR Fortessa flow cytometer. Flow cytometric analysis
of renal cell carcinoma and bladder tumor-derived organoids was performed
using a BD Accuri 6 plus (BD Biosciences) and analyzed with FlowJo
software (Tree Star, Ashland, OR).
