Embodiment

[0016] Select acrylamide and / or methacrylamide with a weight concentration of 3.0-6.5% and methacrylic acid with a weight concentration of 0.1-0.4% as functional monomers, and a cross-linking agent N, N`-sub Methyl bisacrylamide or piperazine bisacrylamide were co-dissolved in 10 mM phosphate buffer solution (pH 4.5-7.5). Nitrogen gas is passed through to remove dissolved oxygen therein, and then template protein molecule lysozyme, cytochrome C or bovine serum albumin with a weight concentration of 0.15-0.55% is added. Place it at 0-4°C for 2-5 minutes, add initiator ammonium persulfate with a weight concentration of 0.08-0.2% and an accelerator N, N, N`, N`-tetramethylethane with a weight concentration of 0.1-0.15% diamine. After mixing evenly, quickly inject it into the liquid chromatography column, and place it at -5~-20°C for 1~12 hours.

[0017] The weight concentrations of the above substances are their final concentrations in the buffer solution.

[0018] For the pre...

Abstract

The invention relates to a method for preparing a protein molecular engram block polymer. Functional monomers, crosslinking agents and model protein molecules in proper proportions stand for 2 to 5 minutes at the temperature ranging from 0 to 4 DEG C, and a certain amount of evocating agents and rate accelerating materials are orderly added later. The mixture is put under the environment whose temperature ranges from minus 5 DEG C to minus 20 DEG C after being rapidly injected into a liquid chromatogram column jacket and polyreaction is completed within 1 to 12 hours. The model protein molecules are eluted by dodecyl sodium sulfate whose weight concentration is 10 percent and acetic acid solution whose volume concentration is 10 percent, namely, a macroporous protein molecular engram monolithic column can be prepared. The invention has the advantages as follows: the preparation method is simple and reliable, and the obtained protein molecular engram monolithic column has stronger template molecule recognition property. The technique provides a novel preparation method for developing protein molecular engram monolithic column.

Description

technical field [0001] The invention relates to the preparation of a liquid chromatography column, in particular to a preparation method of a novel protein molecularly imprinted monolithic column. Background technique [0002] Molecular imprinting (molecular imprinting) is a polymer synthesis technology developed in recent years based on the molecular recognition mechanism, which is selective for specific molecules (template molecules or imprinted molecules). Often described as a technique for creating artificial "locks" that recognize "molecular keys". For example, in non-covalent molecular imprinting, the target molecule is usually used as a template, and the molecule is assembled with a polymerizable functional monomer through hydrogen bonding, electrostatic interaction, hydrophobic interaction, etc., and a polymerization reaction occurs in a crosslinking agent. After the reaction, the imprinted molecules are removed to form holes in the polymer with precisely arranged f...
