摘要:
The present invention relates to a method of sterilizing a chromatography column which is packed with a separation matrix, which method comprises passing a super-heated aqueous liquid through the packing of the column to obtain at least one substantially sterile packed chromatography column. The method may also comprise a preceding heating. In the most advantageous embodiment, the superheated aqueous liquid is passed in a substantially uniform flow through the packing of the column, resulting in a sterility of the packed column.
摘要:
This application describes apparatus and methods using ultrasound transmitted through a chromatography column bed to determine the status of materials in the bed space, particularly during chromatography runs. Detected conditions include the profile of a band of eluting material - to see whether it is satisfactory - the arrival of a band of material at the column output, the fitness for use of the bed packing, the passage of different mobile phases e.g . salt fronts, and other conditions. Aspects claimed include control processors and corresponding programmed products.
摘要:
Apparatus and methods for separating different polynucleotide populations in a mixture are provided, wherein different polynucleotides or polynucleotide populations are captured on different solid support. After hybridization, polynucleotides are selectively released from a selected support by altering a physical property of that support. The released polynucleotides can be eluted from a common flow path and isolated.
摘要:
In certain embodiments, the invention provides a method of purifying a protein of interest from a mixture which comprises the protein of interest and one or more contaminants, said method comprising: a) subjecting the mixture to a first chromatography matrix, wherein the protein of interest binds to the first chromatography matrix; b) contacting the first chromatography matrix with a first wash solution which has a pH of at least 9.0, and does not comprise arginine or an arginine derivative; and c) eluting the protein of interest from the first chromatography matrix into an elution solution.
