Abstract: This invention relates to the identification of modified cytosine residues, such as 5-methylcytosine (5mC), 5-hydroxymethylcytosine (5hmC) and 5-formylcytosine (5fC) to be distinguished from cytosine (C) in a sample nucleotide sequence. Methods may comprise oxidizing or reducing a first portion of polynucleotides which comprise the sample nucleotide sequence; treating the oxidized or reduced first portion and a second portion of polynucleotides with bisulfite; sequencing the polynucleotides in the first and second portions of the population following steps ii) and iii) to produce first and second nucleotide sequences, respectively and; identifying the residue in the first and second nucleotide sequences which corresponds to a cytosine residue in the sample nucleotide sequence. These methods may be useful, for example in the analysis of genomic DNA and/or of RNA.

Abstract: Methods and apparatuses relating to large scale FET arrays for analyte detection and measurement are provided. ChemFET (e.g., ISFET) arrays may be fabricated using conventional CMOS processing techniques based on improved FET pixel and array designs that increase measurement sensitivity and accuracy, and at the same time facilitate significantly small pixel sizes and dense arrays. Improved array control techniques provide for rapid data acquisition from large and dense arrays. Such arrays may be employed to detect a presence and/or concentration changes of various analyte types in a wide variety of chemical and/or biological processes.
Abstract: The present invention relates to the combination of organic acid salts with at least one active ingredient of plant origin, preferably essential oils, partially protected with vegetable fats and/or oils, which prevent these active ingredients from being digested by stomach enzymes during the digestive process. The sodium salts of short-chain acids, preferably salts of butyric, acid are preferred. The preferred essential oils are ginger, piperine, oregano, garlic, thymol, carvacrol, cinnamaldehyde and/or any combinations thereof. The combination of organic acid salts and the essential oils protected with vegetable fats and/or oils, are used as powerful promoters or stimulants for animal growth, as organic bactericides against pathogenic bacteria present in said animals and as modulators of immune response thereof.
Abstract: In a first aspect, the invention relates to the use of a UV-polymerizable composition as an embedding medium for biological samples.
