Expression of mRNA transcripts encoding trkA, trkB, and trkC genes in the HMC-1 mast cell line, the K-562 chronic myelogenous leukemia cell line, and fetal monkey brain tissue. The cDNA was synthesized from total RNA by reverse transcriptase and amplified by PCR using two degenerate oligonucleotide primers A and B. The identity of the PCR products was confirmed by Southern blot analysis using 32P-labeled human trkA, monkey trkB, and monkey trkC probes.
