TI - A Total Extract Dot Blot Hybridization Procedure for mRNA Quantitation in Small Samples of Tissues or Cultured Cells KW - RECOMBINANT DNA TECHNOLOGY KW - MRNA KW - RNA: DNA: GENE EXPRESSION N2 - A simple method for the estimation of specific mRNA concentrations in small tissue samples (as little as 1 mg)or cultured cells (lower limit IO5 cells)is described. Guanidine hydrochloride extracts of whole cells or tissues are applied directly onto nitrocellulose and hybridized with the appropriate nick-translated probe. Loading according to DNA content allows expression ofthe result as concentration per cell. Hybridizing with a ribosomal RNA probe allows expression of results relative to rRNA and estimation of the RNA/DNA ratio in the sample. We describe the application of this procedure to the measurement of ceruloplasmin mRNA in tissues and cultured hepatocytes UR - https://drive.google.com/file/d/1gwe3XIwUi-aNhBUWf2KiNkhVlGc3pnG_/view?usp=drivesdk ER -
