    Abstract: A method for removing an N-terminal truncated variant and an abnormal variant in recombinant human nerve growth factor (rhNGF) is provided. An rhNGF raw material loaded on a cation-exchange material is washed with a washing liquid to obtain a washed raw material from which an N-terminal truncated variant and an abnormal variant have been removed, where the washing liquid has higher electrical conductivity than the rhNGF raw material. Cation-exchange chromatography (CEC) elution is then performed on the washed raw material with an elution buffer having higher electrical conductivity than the washing liquid. A purified rhNGF product is obtained from the eluate.

  • Patent number: 10837278
    Abstract: A device and a method for evaluating a gas-water two-phase flow fracture conductivity of a fractured shale. The device includes a seepage system, an injection system, a data collecting and processing system and a three-axis shale core holder, wherein the seepage system is subjected to two stages including a water injection stage and a gas flooding stage. When using the device, firstly the initial permeability and initial mass of the shale sample are determined; the water influx test is performed by injecting water to the shale sample until flow rate of the water discharged from the shale core is stable, then the water injection is ended. After the drying device is installed, the shale sample is subjected to gas flooding, and the aqueous fracturing fluid discharged by the gas flooding is collected until the flow meter determines that the gas volume is stable, and then the gas flooding is ended.
