Abstract: A novel dry down buffer is provided for use in drying a plurality of fluorescent dye conjugates on a substrate for use in flow cytometry. The aqueous buffer comprises a water-soluble monomer; a protein stabilizer; a carbohydrate stabilizer; and a zwitterionic surfactant. When mixed with a multi-color panel comprising fluorescent polymer dye conjugates, dried on a substrate, and reconstituted with a biological sample, the buffer provides decreased aggregation of fluorescent polymer dye conjugates, and decreased non-specific binding of monocytes and granulocytes, when compared to use of a buffer without the water-soluble monomer or zwitterionic surfactant.

Abstract: A usual ink composition can be expected to improve ink viscosity to a certain degree, but when used for a glycol ether-based ink recently required, an increase in viscosity in preparing the ink cannot be suppressed. In addition, there is unknown a copper phthalocyanine pigment composition which can satisfy both such an improvement in ink viscosity and resolubility as printability which is important for the glycol ether-based ink. In this situation, a problem to be solved by the present invention is to provide a copper phthalocyanine pigment composition having low viscosity and excellent resolubility in a glycol ether-based ink. It was found that when a copper phthalocyanine pigment is combined with a specified copper phthalocyanine acid derivative, a pigment composition having significantly low viscosity when formed into a glycol ether-based ink, and good familiarity with the ink can be produced, leading to the achievement of the present invention.

Abstract: The invention relates to a method for preparing high-stability liquid blueberry anthocyanins, belonging to the field of food processing. A method for preparing high-stability liquid blueberry anthocyanins comprises the following process steps: adding graphene oxide and chitosan to an MES buffer solution at room temperature, mixing homogeneously and adding EDC and NHS sequentially, reacting to obtain a first solution; adding dry blueberry anthocyanin powder in the first solution, adjusting pH to 4.5 to 5.0 and mixing homogeneously to obtain a second solution, and treating the second solution at 350 to 420 MPa and 2 to 4° C. to obtain the product. The method for increasing the stability of blueberry anthocyanins provided by the present invention uses dry blueberry anthocyanin powder as a raw material and adds graphene oxide combined with chitosan compound as an anthocyanin stabilizer, thereby increasing the stability of blueberry anthocyanins during processing and production.
