The recombinant adenovirus freeze-dried preparation disclosed by said invention is the preparation which is obtained after the aqueous solution prepared by using recombinant adenovirus: protective agent (volume ratio)=1:(0.8-1.2) is frozen and dried. The above-mentioned protective agent contains animal glue, sugar, inorganic salt and amino acid culture balanced salt whose pH value is 7.2-8.0. Said recombinant adenovirus freeze-dried preparation is safe, and high in effect and good in stability.
Description
Technical field:
The invention belongs to biological preparation and preparation field, be specifically related to recombinant adenovirus lyophilized formulations and preparation method.
Background technology:
Along with going deep into gradually of gene therapy research, the development of advancing by leaps and bounds has been arranged as its basic viral vector research.Adopt the gene transfer technique treatment human diseases of viral vector not only to study, and entered into clinical experimental stage in the chamber of experimentizing.Adenovirus is pathogenic little and do not induce canceration to the people because of it, and host cell is wide, breeding titre height, and struck capacity is big, and becomes the focus of viral vector research in recent years.Even if but the liquid recombinant adenovirus toxin preparation that contains stabilizing agent is also comparatively responsive to temperature, bring big difficulty for transportation, preservation, this has limited its application clinically to a great extent.Up to the present, Shang Weiyou can be in the lyophilizing recombinant adenovirus toxin preparation listing of 4-8 ℃ of long preservation.
Summary of the invention:
Technical problem to be solved by this invention is to solve existing recombinant adenovirus stability of formulation, provides a kind of safe, efficient, good stability, effect duration long lyophilization recombinant adenovirus toxin preparation.
Recombinant adenovirus lyophilized formulations disclosed by the invention is to be recombinant adenovirus by volume ratio: protective agent=1: the preparation that the aqueous solution that (0.8-1.2) is mixed with obtains after lyophilization, wherein to comprise animal glue, sugar, inorganic salt and pH be that 7.2-8.0 aminoacid is cultivated balanced salt to protective agent.
Recombinant adenovirus of the present invention is meant genetic engineering modified adenovirus.
Animal glue of the present invention is selected from gelatin, osseocolla or hide glue etc.;
Described sugar is selected from one or more in sucrose, mannitol, trehalose, lactose, the maltose;
Described inorganic salt is selected from one or more in sodium chloride, potassium chloride, potassium dihydrogen phosphate, sodium hydrogen phosphate, calcium chloride, the magnesium chloride;
Described aminoacid culture medium balanced salt is selected from commercially available basic aminoacid culture medium (Dulbecco ' s Modified Eagle Medium, be called for short D-MEM) balanced salt.
The animal glue and the sugar that adopt in the lyophilized formulations protective agent of the present invention can play the support effect, if add the heat stability that trehalose can improve the live virus preparation; The inorganic salt that adopts is for the pH value of regulating preparation and wait and ooze a little, to satisfy physiological adaption requirement and safety of medicine, stable, effective requirement; The pH value that adopts is that the aminoacid culture medium balanced salt of 7.2-8.0 is a cosolvent, to increase the dissolubility of adenovirus, enhanced stability.
In protective agent of the present invention, also can add other compositions: cosolvent such as carbamide, monosodium glutamate etc.; Antioxidant synergist such as L-cysteine etc.; With further raising stability of formulation.
The preferred final weight volume of protective agent each component of the present invention (w/v) concentration is animal glue 0.5-2.0%, sugar 1.5~21.5%, and inorganic salt 0.1~12%, aminoacid is cultivated balanced salt 0.5~2%.
Protective agent of the present invention is preferably filled a prescription and is consisted of (w/v) sucrose 1.5-5.5%; mannitol 4.5-10.5%; gelatin 0.5-2.0%; L-cysteine 0.03-0.15%; trehalose 1.5-5.5%; potassium chloride 0.1-0.3%; potassium dihydrogen phosphate 0.1-0.3%; pH value is basic aminoacid culture medium (D-MEM) balanced salt 0.5~2% of 7.2-8.0; sodium chloride 3.5~8.5%, sodium hydrogen phosphate 1.2~2.9%, carbamide 0.4~1.2%; monosodium glutamate 0.4~1.2%, all the other are the pure water of resistivity=18.2M Ω/cm.
Another technical problem to be solved by this invention is to provide the preparation method of above-mentioned recombinant adenovirus lyophilized formulations.
The preparation of recombinant adenovirus lyophilized formulations disclosed by the invention comprises the following steps:
By above-mentioned protective agent prescription, take by weighing each component, add pure water to prescribed volume and fully dissolve, standby; Again recombinant adenovirus is pressed interior gland-containing virus amount 1.0 * 10
12The concentration of granule number/ml is with 1: (0.8-1.2) join in above-mentioned protectant solution; fill; preparation is put into freeze drying box; pre-freeze is to-30 ℃--40 ℃, kept evacuation 3-5 hour; distillation; dry again, make formulation temperature by 0 ℃-35 ℃, promptly make lyophilization recombinant adenovirus toxin preparation.
Recombinant adenovirus lyophilized formulations with prescription of the present invention and method prepare detects evidence through infection titer, and preparation has kept the original activity of recombinant adenovirus; And have good stability through 30 months stability test proof.Compared with prior art, technology of the present invention is reasonable, safety and good stability, and effect duration is long, provides good prospects for application for adopting recombinant adenovirus as the clinical experiment of the gene therapy of carrier.
