Fig 2. HEK293T cells are heterozygous for CCR5 delta32 mutation.
(A) The CCR5 PCR products from Jurkat, MAD-MB-231 and HEK293T cells were resolved in 3% agarose gel. Upper, middle and lower bands are indicated. “NC” stands for no template negative control. (B) Sequencing chromatograms from the middle, lower, and upper bands (two directions) are showed.
