Embodiment 1

[0107] 1. Preparation of allophycocyanin

[0108] Cell disruption

[0109] Weigh Spirulina platensis into a beaker, wash it twice with distilled water, add a phosphate buffer with a pH of 5.8 and a concentration of 0.005 mol / L, and stir evenly. In an ice bath (0°C), 1800W ultrasonically broken for 30 minutes, the broken algae liquid is placed in a pre-cooled high-speed refrigerated centrifuge, and centrifuged at 8000 revolutions per minute (rpm) at 0°C for 60 minutes. The precipitate is removed and collected. Clear liquid

[0110] Salting out

[0111] Add solid ammonium sulfate to the supernatant to reach 25% saturation, let it stand at 0°C for 10 hours, and centrifuge at 6000 revolutions per minute (rpm) at 0°C for 60 minutes, and discard the precipitate. Continue to add solid ammonium sulfate to the supernatant to 80% saturation, let stand at low temperature (0°C) for 10 hours, and centrifuge at 6000 revolutions per minute (rpm) at 0°C for 60 minutes. Discard the supernatant and...

[0133] 1. Preparation of allophycocyanin

[0134] Cell disruption

[0135] Weigh Spirulina platensis into a beaker, wash it twice with distilled water, add a phosphate buffer with a pH of 6.8 and a concentration of 0.005 mol / L, and stir evenly. In an ice bath (0°C), 1800W ultrasonically crushed for 40 minutes, the crushed algae solution was placed in a pre-cooled high-speed refrigerated centrifuge, centrifuged at 8000 revolutions per minute (rpm) at 2°C for 45 minutes, the precipitate was removed and collected. Clear liquid

[0136] Salting out

[0137] Add solid ammonium sulfate to the supernatant to reach 25% saturation, let it stand for 12 hours at a temperature of 2°C, centrifuge at 8000 revolutions per minute (rpm) at 2°C for 40 minutes, and discard the precipitate. Continue to add solid ammonium sulfate to the supernatant to 80% saturation, let stand at low temperature (2°C) for 10 hours, centrifuge at 8000 revolutions per minute (rpm) at 2°C for 45 minutes, discard the supe...

Abstract

The present invention relates to a protein, crystal preparation process and its product, in particular, it relates to an allophycocyanin which is extracted from algae under the general condition and can emit strong fluorescence, and can convert it into crystal form. It can be extensively used in the fields of scientific research, medicine, detection and telecommunication, etc.

Description

Technical field [0001] The present invention relates to a protein and crystal manufacturing process and products, in particular to allophycocyanin that is extracted from algae under normal conditions and can emit strong fluorescence and converts it into a crystal form, and it is used in scientific research, medical treatment, etc. Applications in the fields of detection, information and telecommunications. Background technique [0002] As early as the beginning of the last century, foreign countries have reported the existence of red, violet and blue proteins with strong fluorescence in cyanobacteria and red algae. In 1910, Kylin named these pigment proteins "Phycochromo-proteins" for the first time. This kind of light-harvesting pigment protein, which appears in large quantities in red algae, blue-green algae and cryptophyte, is the phycobiliprotein (PBP) that needs to be developed urgently. It mainly includes phycoerythrin (Phycoerythrin, PE) and phycocyanin. (Phycocyanin, PC),...
