The invention provides methods for isolating cell-type specific mRNAs by selectively isolating ribosomes or proteins that bind mRNA in a cell type specific manner, and, thereby, the mRNA bound to the ribosomes or proteins that bind mRNA. Ribosomes, which are riboprotein complexes, bind mRNA that is being actively translated in cells. According to the methods of the invention, cells are engineered to express a molecularly tagged ribosomal protein or protein that binds mRNA by introducing into the cell a nucleic acid comprising a nucleotide sequence encoding a ribosomal protein or protein that binds mRNA fused to a nucleotide sequence encoding a peptide tag. The tagged ribosome or mRNA binding protein can then be isolated, along with the mRNA bound to the tagged ribosome or mRNA binding protein, and the mRNA isolated and further used for gene expression analysis. The methods of the invention facilitate the analysis and quantification of gene expression in the selected cell type present within a heterogeneous cell mixture, without the need to isolate the cells of that cell type as a preliminary step.

A detachable, heat resistant, flexible button protector protects against button degradation during laundering, dry-cleaning or hot ironing operations. The protector has an enclosure for forming a cavity surrounding at least one button. A slit in the side of the enclosure accommodates insertion of the button into the cavity. Button degradation is prevented by sealing the enclosure to minimize penetration of cleaning fluids during insertion and residence of the button within the cavity. The protector shields the button from corrosive laundering and dry-cleaning chemicals, while allowing entry of chemicals that wash the fabric on which the button is sewn. It is strong enough to withstand compressive force and shock impact produced by laundering machinery. Chipping and chemical degradation of buttons is virtually eliminated. Laundering, dry-cleaning and ironing operations are carried out economically in an efficient, reliable manner.
