Abstract

The invention provides a preparation method of refined poly zic and application, which are characterized in that polyinosinic acid and poly zic acid are purified via a chemical method, are merged into poly zic liquor after being refined respectively, and the poly zic liquor is ultra-filtered, concentrated and added with auxiliaries, so that the refined poly zic is prepared. The refined poly zic can effectively increase an anticancer effect.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to the preparation method and application of refined polymyocytes. Background technique [0002] Polyinosin is an interferon inducer. It produces interferon under the induction of cells in the body, which has a similar effect to interferon, so it has broad-spectrum anti-virus and immune regulation functions. Adjuvant therapy for viral infectious diseases and tumors. [0003] At present, researches on using polymyocytes as vaccine adjuvants have been carried out in China. Among them, the Chinese patent has published the patent number 93105862.7, the name is: polymyocyte complex immune adjuvant and the vaccine containing the adjuvant and the patent number is 200810011586.6, The name is: Freeze-dried vaccine and its dilution solution respectively packaged vaccine product and preparation method of the dilution solution. [0004] There are also articles titled PICA Adjuvant and PI...
