摘要:
We disclose a PS4 variant polypeptide derivable from a parent polypeptide, the parent polypeptide having non-maltogenic exoamylase activity, which PS4 variant polypeptide comprises one or more of the following substitutions: G69P, A141P, G223A, A268P, G313P, S399P and G400P, with reference to the position numbering of a Pseudomonas saccharophilia exoamylase sequence shown as SEQ ID NO: 1. Such PS4 variant polypeptides may be used as exo-amylases, particularly as non-maltogenic exoamylases. Combinations of such PS4 variant polypeptides together with Novamyl are disclosed.

摘要:
The present invention relates to a method, a chip, a device, and a system for collection of biological particles. The method makes use of electrostatic attraction of biological particles to charged electrodes and preferably operates with gaseous samples. The method, chip, device, and system are e.g. useful for collecting pathogenic biological particles, such as bacterial spores and vira, from air samples and allow for subsequent analysis of the collected biological particles.
摘要:
The present invention relates to a method, a chip, a device, and a system for detection of biological particles. The method of the invention typically comprises collecting the biological particles from a gaseous sample, contacting the biological particles with a first liquid reagent, extracting biological material from the collected biological particles, and analyzing the biological material for the presence of a target nucleic acid sequence.
摘要:
The present invention relates to a method, a chip, a device and a system for extraction of biological material form biological cells. The invention involves exposing the biological particles to an alternating electric field in a sample chamber and may also involve subsequent analysis of the biological material after the extraction.
摘要:
The present invention provides genes encoding variants of metallo-endopeptidases that have been engineered to be resistant to prolonged boiling while having maintained their enzymatic performance at much lower temperatures. In addition, thermal stability of the metallo-endopeptidases is highly dependent on calcium at concentrations in the mM range. The invention further provides active metallo-endopeptidases variants whose stability depending on calcium concentration can be changed so as to provide metallo-endopeptidases that are calcium dependent or independent. The invention also provides genes that encode boiling-resistant metallo-endopetidases whose stability depending on calcium concentration can be changed. The invention also provides vectors and cells comprising these genes and proteases produced through these genes, vectors and/or cells. In particular variants with the above described properties are provided of thermolysin-like proteases such as produced by Bacillus stearothermophilus (TLP-ste) and Bacillus thermoproteolyticus (thermolysine). Boiling-resistant and calcium independent or dependent metallo-endopeptidases can be applied in several industrial processes, for instance in the preparation of the artificial sweetener aspartame, but also in the leather industry, in breweries and in the production of protein hydrolysates.
摘要:
The present invention relates to a method, a kit and a system for sensitive detection of a target nucleic acid molecule. The target nucleic acid molecule may e.g. be specific for a certain microorganism, e.g. a pathogenic microorganism such as B. anthracis. The methods and kits relate to so-called nested PCR and especially improvements, which renders the nested PCR technique better suited for automated analysis.
