GeneQuant Spectrophotometer is an RNA/DNA calculator tool that measures absorbance at 230, 260, 280, 320, 546, 562, 595 and 600 nm. It can determine the concentration and purity of nucleic acids after PCR amplification, calculate annealing temperatures for primers prior to PCR upon entry of the oligonucleotide sequence and concentration and the total buffer molarity, measure Optical Density 600 for bacterial cell culture solutions, and it may be used for protein determination using the Bradford, Biuret, and BCA protein assays.
A rapid detection of probiotic activity reagent device and equipment
The present application relates to the field of probiotic activity detection, in particular to a reagent device for rapid detection of probiotic activity and equipment, comprising a shaking cup and a shaking device; the reagent device further comprises: a separation ring coaxially arranged in the shaking cup along the axis of the shaking cup, the diameter of the separation ring is the same as the diameter of the shaking cup, and the separation ring is made of a deformable material; a sampling device arranged at the upper part of the shaking cup; a storage cup arranged in a straight line with the shaking cup, and a plurality of storage cups are used to store reagents and probiotic samples respectively; a first linear driver for driving the sampling device to reciprocate along the arrangement direction of the storage cup; and an ultraviolet spectrophotometer arranged on one side of the storage cup and located on the moving path of the sampling device. The present application avoids the scattering and shielding interference of foam on the light path, and improves the reliability of the data.

A method for detecting the content of biomarker GSH based on TMB colorimetry
This invention belongs to the field of biochemical detection technology and discloses a method for detecting the content of the biomarker GSH based on TMB colorimetric method. The specific technical solution is as follows: Step 1: Hydrogen-bonded organic framework is synthesized by hydrothermal method, and the transition metal Fe is introduced for modification to obtain HOF-Fe material; Step 2: Acetic acid-sodium acetate solution is used as background solution, TMB solution and H2O2 solution are added respectively, and finally HOF-Fe is added to react. The peroxidase-like activity of the material is measured by ultraviolet spectrophotometer; Step 3: Glutathione solution of different concentrations is added to the above reaction system to quantitatively detect glutathione. This method constructs a high-performance colorimetric sensor by preparing a novel HOF-Fe nanozyme, which can realize rapid, high-sensitivity and high-specificity detection of glutathione, and can be widely used in the determination of glutathione content in actual samples.
