    摘要： The invention is directed to a method for obtaining a nucleic acid library of a sample comprising polynucleotides comprising the steps a. multiplying the polynucleotides by a polymerase b. fragmenting the multiplied polynucleotides by creating nicks c. coupling an oligonucleotide sequence to the nicks to create the target library wherein step a) is performed by providing A, T, G, C and U nucleotides wherein the molar ratio of T and U is between 200:1 and 5:1 and step b) is performed by excision of the U nucleotides. characterized in that after step b), the nicks are provided with a polymerase exhibiting 5′ #3′ exonuclease activity, thereby filling in the 3′ recessing ends and removing the 5′ overhangs of the nicks.

    摘要： The invention is directed to a peristaltic pump (10), comprising: a flexible membrane (1) forming a at least one bladder (2) against a support, wherein each bladder is provided with one input orifice (4) which admits a fluid to the bladder (2) and one outlet orifice (5) which releases the fluid from the bladder (2); and at least one roller bearing (6) is configured to rotate about an axis (7) and to apply a compressive force against the at least one bladder (2). The peristaltic pump may be in fluid communication with a tapered jet (11).
