Figure 1
Expression of MITF isoforms and beta-tryptase genes in HMC-1 cells and hMC. Total RNA was extracted from HMC-1, hMC and 293 cells as a tryptase-negative cell line. The transcripts of MITF isoforms (A) and tryptase beta1 and beta 2 (B) were analyzed by RT-PCR. PCR products were electrophoresed in 1% agarose gel.
