Amplification of HLA class
II and flanking region genes. Genomic DNA of CTL (lane 1) and My-La
(lane 2), cDNA of CTL (lane 3) and My-La (lane 4) and non-template
DNA (lane 5) were amplified with pairs of primers that were derived
from the indicated genes Tap2 (calculated sizes: 2197 and 345 bp
for genomic DNA and cDNA, respectively), HLA-DQα (763
and 351 bp for genomic DNA and cDNA, respectively), HLA-DRB1 (1728
bp for genomic DNA), HLA-DRα (165 bp
for cDNA) and Notch4 (329 and 209 bp for genomic DNA and cDNA, respectively).
Amplification of genomic DNA and cDNA with primers from HLA-DRα (calculated size: 904 bp) and HLA-DRB1
(250 bp), respectively, were not shown but confirmed the shown results.
The PCR products were electrophoretically separated on a 1.5% agarose
gel and stained with ethidium bromide. M, 100 bp ladder size marker.
