IL-13Rα1 expression by HL cell lines.
The cDNA was prepared from HL cell lines (KM-H2, HD-LM2, L1236, L540Cy, and L428) and amplified by PCR using IL-13Rα1–specific oligonucleotides, followed by agarose gel electrophoresis. The presence of the 430-bp PCR product indicates IL-13Rα1 gene expression in all 5 HL cell lines examined. Negative control (−): H20; positive control (+): cDNA from BL-31 cells. MW = 100-bp ladder.
