The invention discloses a composite water-soluble immunologic adjuvant and a preparation method thereof. The composite water-soluble immunologic adjuvant is prepared from the following components in parts by weight: 18-22 parts of phosphate buffer salt solution dry powder, 1-3 parts of sodium ascorbate, 8-12 parts of beta-glucan, 4-8 parts of xanthan gum and carrageenan mixture, 8-14 parts of plant extract, 2-5 parts of plant polysaccharide and 1930-1960 parts of ultrapure water. According to the adjuvant, the problem that a specific antibody is generated for the adjuvant is effectively avoided, the detection rate of positive clone is remarkably increased, and the possibility of obtaining a high-quality paired antibody is increased. The mixing process of the adjuvant and the water-soluble antigen is simple and does not need emulsification. The native conformation of the antigen is retained, and the generation of antibodies aiming at conformation-dependent epitopes is facilitated. Compared with traditional Freund's adjuvants and incomplete Freund's adjuvants, the composite water-soluble adjuvant has the advantages that the use amount of antigens is small, the immune cycle is shortened, efficient immune response and antibody generation can be quickly stimulated, and the composite water-soluble adjuvant has remarkable competitive advantages.

The invention provides a hidden attack sample data labeling method, and belongs to the field of artificial intelligence and data security. The method comprises the following steps: firstly, carrying out an attack data labeling process: executing by an attacker, presetting an immune agent by the attacker, effectively interfering a target agent by wrongly written characters generated by the immune agent on the premise of keeping the overall fluency and readability of a text, and meanwhile, ensuring that the target agent is harmless to the own agent; and then carrying out an immune agent detection process. According to the method, interference information such as wrongly written characters and similar characters can be accurately inserted on the basis of ensuring the readability of a text through an intelligent algorithm, so that the purpose of directional attack on a target agent is achieved, and meanwhile, adverse effects on an own agent are effectively avoided; according to the method, hidden labeling of the attack sample can be realized, pollution attack on the target intelligent agent is realized, the influence on the own intelligent agent is avoided, and the method is widely applied to the aspects of poisoning training data, attacking the intelligent agent and the like.

The invention discloses a galactan with immune adjuvant activity and a preparation method and application thereof.

The invention belongs to the field of biological medicine, and relates to application of dendritic polypeptide in preparation of a training immune agent. The technical problem to be solved by the invention is to stimulate and regulate an immune system by using a training immune agent so as to improve the resistance of a body to diseases. According to the scheme for solving the technical problem, the application of the dendritic DP7 polypeptide serving as a training immune agent to activate organism immunity is provided. The new application of the dendritic DP7 polypeptide can activate specific cells of the spleen to generate rapid immune response aiming at subsequent disease molecules, improves the resistance and treatment effect of the organism on diseases, is expected to bring important breakthrough to the fields of disease treatment and immune regulation, and improves the living quality and treatment effect of patients. Meanwhile, the invention also provides a powerful immunological research tool and method for researchers in related fields, and has a good application prospect.

The invention relates to the technical field of medical instruments, and discloses glioma postoperative immune combined oncolytic virus implantation equipment which comprises a release pipeline, the left side face of the release pipeline is communicated with an immune preparation storage bin, and the right side face of the release pipeline is communicated with an oncolytic virus storage bin.
