Hi Netters, I am looking for a clone of PIG ribosomal DNA ( 18s, 28s or both) to be used as an internal standard in my RNase protection assays. All I need is about 100 base pairs of ribosomal DNA. I would appreciate if anyone can send me a few molecules of a clone. Thanks in advance for your assistance. O.P.Perera University of Florida OPP at ICBR.IFAS.UFL.EDU
