Figure 1From: Multigene family isoform profiling from blood cell lineagesKir family isoform profiling strategy. 1) Alignment of Kir channel isoform nucleic acid sequences revealed regions of high sequence similarity. Two conserved motifs, G(Y/F)G and ILE, in the pore and C terminal domains respectively, were selected and Kir isoforms cloned. 2) Poly A+ RNA was isolated from a single cell type and 3) degenerate (dg) PCR performed with sub-family centred primers. Degenerate PCR products were radio end-labelled, recovered free of unincorporated nucleotides and cleaved with frequent-cutting restriction enzyme (ScrF I) and resolved by agarose gel electrophoresis.Back to article page
