we have used the polymerase chain reaction ( pcr ) with primers against the s5 and s6 regions of voltage-gated k+ channels to identify 8 different specific amplification products using poly ( a ) + rna isolated from islets of langerhans from obese hyperglycemic ( ob/ob ) mice and from the two insulin-producing cell lines hit t15 and rinm5f .
