The present invention provides a GFAP, NFL and UCH-L1 combined detection kit, comprising: an acridinium ester labeled antibody working solution and a magnetic bead coated antibody working solution; the acridinium ester labeled antibody working solution contains acridinium ester labeled GFAP, NFL and UCH-L1 antibodies, and the magnetic bead coated antibody working solution contains magnetic bead coated GFAP, NFL and UCH-L1 antibodies. By screening the components and the content of each component of the acridinium ester labeled working solution and the magnetic bead labeled working solution, a stable working environment can be provided for the acridinium ester labeled GFAP, NFL and UCH-L1 antibodies and the magnetic beads labeled with the GFAP, NFL and UCH-L1 antibodies, and specific recognition and detection of GFAP, NFL and UCH-L1 are achieved, thereby realizing the triple detection of GFAP, NFL and UCH-L1 for early diagnosis of patients with brain trauma.

This invention relates to the field of preparation technology of terephthalic acid dicamphor sulfonate organic amine salt, and particularly to a method for synthesizing terephthalic acid dicamphor sulfonate organic amine salt, comprising the following steps: neutralizing camphor sulfonic acid with an organic amine compound in a solvent to generate camphor sulfonate organic amine salt; and condensing camphor sulfonate organic amine salt with terephthalaldehyde under the catalysis of a non-metallic organic alkaline catalyst to obtain terephthalic acid dicamphor sulfonate organic amine salt. The method employs an organic amine neutralization and non-metallic organic alkaline catalytic system, avoiding the introduction of metal ions throughout the process. The product is terephthalic acid dicamphor sulfonate organic amine salt, and no subsequent ion exchange treatment is required, resulting in higher product safety, making it particularly suitable for high-end applications such as sunscreen cosmetics.

The present invention relates to the field of biodegradable materials, particularly to a lactide production method, which comprises: (1) carrying out a condensation polymerization reaction on lactic acid in a condensation polymerization reaction kettle in the presence of rare earth steel to obtain a lactic acid oligomer with a polymerization degree of less than 10; and (2) carrying out a depolymerization reaction on the lactic acid oligomer in a depolymerization reaction kettle in the presence of rare earth steel to obtain a product containing lactide. According to the method provided by the invention, the yield of the high-gloss pure lactide can be improved, the chemical purity of the product can be guaranteed, and the purification difficulty is reduced.
