    摘要： Methods of creating libraries of biological polymers are provided. The construction of a library employs a probability matrix for a reference sequence, and a constraint vector for which is applied to the probability matrix to produce a substitution scheme. The substitution scheme is then used to generate a library comprising substitutions recommended by the substitution scheme. The library members, or host cells comprising and/or expressing them, can be screened for desired changes in a property of interest in the biological polymers in the library.

    摘要： Novel protease variants derived from the DNA sequences of naturally-occurring or recombinant non-human proteases are disclosed. The variant proteases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant protease to generate the substitution of a plurality of amino acid residues in the amino acid sequence of a precursor protease. Protease variants are provided that contain substitutions of the amino acids at one or more residue positions so that the substitution alters the charge at that position to make the charge more negative or less positive compared to a precursor protease and thus the protease variant is more effective in a low detergent concentration system than a precursor protease. Also provided are protease variants containing substitutions of the amino acids at one or more residue positions so that the substitution alters the charge at that position to make the charge more positive or less negative compared to a precursor protease and thus the protease variant is more effective in a high detergent concentration system than a precursor protease.Protease variants are provided that contain substitutions of the amino acids at one or more residue positions so that the substitution alters the charge at that position to make the charge more negative or less positive compared to a precursor protease and thus the protease variant is more effective in a medium detergent concentration system than a precursor protease. Also provided are protease variants containing substitutions of the amino acids at one or more residue positions so that the substitution alters the charge at that position to make the charge more positive or less negative compared to a precursor protease and thus the protease variant is more effective in a medium detergent concentration system than a precursor protease.Further provided is a method of producing a protease variant that is more effective in a low detergent concentration system, medium detergent concentration system and high detergent concentration system than a precursor protease.

    摘要： A method for holding samples for analysis and an apparatus thereof includes a testing plate with a pair of opposing surfaces and a plurality of holes. Each of the holes extends from one of the opposing surfaces to the other one of the opposing surfaces. The holes are arranged in groups, where each group has at least two rows and two columns of holes. The groups are arranged in sets, where each set has at least two rows and two columns of groups. To analyze samples, at least one of the opposing surfaces of the testing plate is immersed in a solution to be analyzed. A portion of the solution enters openings for each of the holes in the immersed opposing surface. Once the holes are filled with solution, the testing plate is removed and is held above a supporting surface. Surface tension holds the solution in each of the holes. The solution in one or more of the holes is then analyzed and the solution in one of these holes is identified for further study. The location of the identified solution is marked based upon its location within a particular set and group of holes.

    摘要： A method is provided for screening microorganisms having a selectable characteristic comprising: (a) providing a growth chamber capable of forming a plurality of discrete compartments, said compartments comprising a barrier which inhibits the diffusion of metabolites or nutrients between said compartments within said growth chamber; (b) preparing a growth medium which, by its lack of or addition of one or more metabolites or nutrients, preferentially facilitates growth of microorganisms exhibiting said selectable characteristic from microorganisms which do not exhibit said selectable characteristic; (c) inoculating said growth medium with a plurality of microorganisms, a portion of which comprise said selectable characteristic; (d) placing said inoculated growth medium into said growth chamber so as to randomly disperse said microorganisms among discrete compartments in said growth chamber; and (e) incubating said growth chamber for a suitable time and under suitable conditions to obtain a detectable disparity of growth between microorganisms having said selectable characteristic and microorganisms lacking said selectable characteristic.
