The present invention pertains to a method to isolate, separate, enrich or amplify a targeted nucleotide polymer such as mRNA through selective reverse transcription of the targeted polymer into cDNA from a sample comprising of chemically identical or similar polynucleotide polymers such as rRNA. The enrichment of the targeted nucleic acid such as mRNA is accomplished by blocking the reverse transcription of undesired rRNA while allowing unrestricted reverse transcription of the targeted polymer. The invention also embodies that the cleavage of the non-targeted nucleic acid such as rRNA bound to an oligonucleotide through enzymatic activity (RNase H). The invention further embodies methods and kits to accomplish the utility of the invention through the following steps 1) 3′ tailing of chemically identical or similar nucleotide polymers in a sample that includes bacterial mRNA 2) a 3′ tail capable of binding to a oligo-dN primer 3) at least one oligonucleotide capable of preventing the extension of oligo-dN bound to at least one non-targeted nucleotide polymers by a DNA polymerase such as a reverse transcriptase without restricting conversion of bacterial mRNA into cDNA 4) where the non-targeted molecule is prevented as a template for cDNA synthesis by enzymatic cleavage (RNase H) of template (rRNA)-oligonucleotide hybrid 5) where the reverse transcriptase is physically blocked by the oligonucleotide bound to the non-targeted nucleic acids such as rRNA 5) purification of the selectively transcribed cDNA. In further embodiments of the present invention, methods and composition to enable the study of bacterial transcriptomics-an analysis of genes expressed by a bacterial infection of a host, an isolated bacterial culture or a bacterial community, such as recovered from soil, intestine, mouth, biofilm, water etc are also included for use in DNA-chip or sequencing analyses.

The present invention is directed towards an apparatus and method for disinfecting biological samples, including semen and the like, and for removing a biological sample pellet from surrounding media while reducing the risk of recontamination of the pellet with said media. An insert receptacle includes a receiving cylinder having a drain in a floor which allows the fluids to decant slowly down the side of a tube. The insert receptacle further includes an aspiration channel which allows an aspiration device, such as a modified micro-pipette, to be utilized for extracting a sample pellet from the bottom of the tube. Utilizing the novel apparatus, a method for reducing pathogens in a biological sample includes decanting the biological sample through the receiving cylinder and into a tube where it passes through a multi-layer gradient including an enzyme suitable for removal of at least one pathogen from the biological sample. Centrifuging of the insert receptacle, tube, and sample, isolates a sample pellet of the biological sample from the surrounding at least one pathogen. After the sample pellet is isolated it is aspirated via the aspiration device without re-contaminating the sample pellet through contact with the surrounding at least one pathogen.

Disclosed is a method for processing porcine cornea using an aqueous NaCl solution and an aqueous trypsin/EDTA solution to decellularize enucleated porcine cornea. The porcine cornea processed by the method causes neither inflammation nor immune rejection. The porcine corneal stroma decellularized by the method can be recellularized together with host keratocytes after transplantation.

wherein a plasma concentration of the 5-HT₃ receptor antagonist in a therapeutically effective range is provided for period of time from an onset time to 12 hours or more after the composition is removed.

A method for preparing the decellularized matrix using the phospholipase includes the following steps: pretreating the standby tissue and organ; putting the standby tissue and organ into the solution containing the phospholipase; preparing the decellularized matrix in the control condition; washing the prepared decellularized matrix.

The present invention is directed to a method and apparatus for disinfection of biological samples, including semen and the like. In a first aspect of the present invention, a method for reducing pathogens in a biological sample includes passing the biological sample through a gradient including an enzyme suitable for removal of at least one pathogen from the sample. In an additional aspect of the present invention, an apparatus for removing pathogens from a biological sample includes a container including a gradient having at least one layer that is suitable for having the biological sample pass through the layer, the at least one layer including an enzyme suitable for removing at least one pathogen from the biological sample.

A method of secretory expression of lysostaphin in Escherichia coli at high level, which comprises constructing a expression vector by cloning a sequence encoding a signal peptide which is suitable for secretory expression in Escherichia coli before part or whole gene sequence which encodes mature lysostaphin, and ligating the cloned sequence with a promoter; and transforming Escherichia coli with the expression vector, culturing and fermenting, and then isolating lysostaphin from the supernatant of the fermentation broth. The advantage of secretory expression is that the expression product can exist in the medium in an active form, and thus does not need the process for renaturation of the inclusion body; it is more easily to purify from the supernatant of the fermentation broth with high rate of recovery; and there is less contamination from the host's proteins.
