PCR analysis of CD23 expression in SMS-SB and other B-lymphoid cell lines. Total cellular RNA was prepared from a range of B-lymphoid and keratinocyte cell lines, and from SMS-SB cultured either in PFHMII or in serum-containing medium. Total cellular RNA was used as template for RT-PCR using the primers indicated and the products were separated by agarose gel electrophoresis and probed with a [32P]-labeled insert from the plasmid pCDL SRα296CD23. Hybridization was visualized by autoradiography.
