Abstract
The present invention relates to a method for preparing tumor vaccine. Petroleum wax is taken for embedding cancer tissue slices, a single-cell suspension solution is prepared. After the cancer tissue slices are washed by a buffer solution, trypsin is added to be placed or put in a microwave oven for treatment, and the cancer tissue slices can be treated by garlicin or an aloe extracting solution. After the cancer tissue slices are washed by the buffer solution, an immunological adjuvant is added, and an aldehyde fixing agent is added. The present invention has the advantages of easy antigen source, simple and convenient preparation method, low cost, wide application, thorough tumor vaccine inactivation, high safety and obvious curative effect.
Description
The invention belongs to the antitumor immune technical field, relate in particular to a kind of method of utilizing the paraffin embedding cancerous tissue to prepare tumor vaccine.
Use the tumour-specific active immunity treatment of tumor vaccine active immunity, for new approach has been opened up in the treatment of malignant tumor with excitating organism internal specific antineoplastic immune power.Because the complexity of tumor antigen, the research of allosome tumor vaccine does not make great progress as yet, and the autologous tumor vaccine then becomes one of research focus in current this area.In the prior art, the preparation of autologous tumor vaccine all is to adopt the cancerous cell of fresh cancerous tissue and work as antigenic source.For example Chinese patent application discloses the method that the fresh cancerous tissue of a kind of usefulness prepares tumor vaccine for No. 93112060.8.But,, can't in treatment, be used widely as the tumor vaccine in antigen source with fresh cancerous tissue, because be difficult to obtain the fresh tumor tissues of patient this moment from body to postoperative recurrence, transfer patient owing to be subjected to the restriction of preservation condition and holding time.If want the above-mentioned tumor vaccine of long preservation, it must be placed cryogenic conditions for a long time, this can cause the aldehydes polymerization, the antigen aldehyde radicalization, thus cover antigen, reduce tumor vaccine effectiveness greatly.In addition, adopt fresh tumor tissues to prepare tumor vaccine,, be difficult to sometimes the thorough deactivation of cancerous cell owing to be subjected to the condition effect such as time, temperature of the effectiveness of Drug resistance, deactivation medicine of cancerous cell and deactivation operation.
Purpose of the present invention will overcome the deficiency of above-mentioned prior art exactly, the tumor vaccine preparation method of provide a kind of antigen to originate easily, preparation method is easy, with low cost, be widely used, the tumor vaccine deactivation is thorough, safe in utilization, evident in efficacy.
The object of the present invention is achieved like this: a kind of method for preparing tumour vaccinum is characterized in that taking the following step:
(1) gets the section of paraffin embedding cancerous tissue,, make single cell suspension through dewaxing, aquation, digestion process;
(2) wash with buffer;
(3) add trypsin and put 3 minutes, or put into microwave oven and handled 10 minutes;
(4) wash with buffer;
(5) add immunological adjuvant;
(6) add aldehyde fixative.
Purpose of the present invention can also realize like this: a kind of method for preparing tumour vaccinum is characterized in that taking the following step:
(1) gets the section of paraffin embedding cancerous tissue,, make single cell suspension through dewaxing, aquation, digestion process;
(2) wash with buffer;
(3) hatched 20～30 minutes with garlicin or Aloe extraction solution;
(4) wash with buffer;
(5) add immunological adjuvant;
(6) add aldehyde fixative.
In order to realize purpose of the present invention better, the used adjuvant of above-mentioned each method is bacillus calmette-guerin vaccine or PPD.
Tumor vaccine preparation method of the present invention, the antigen source is easy, and the patient generally is long-term conventional the file from paraffin body embedding cancerous tissue at its operation hospital pathology department, and the cancerous tissue of depositing is enough to the expense of satisfied preparation tumor vaccine; Preparation method is easy, grasps easily; With low cost, do not need special equipment, be convenient to the less hospital application of basic unit's scale; Can be used for all postoperative tumor patients,, be not subjected to time restriction with using with system; Because the antigen source is the paraffin embedding cancerous tissue, so deactivation is definitely thorough, safe and reliable; The tumor vaccine of preparation has significantly anticancer and metastasis effect, energy excitating organism specificity antineoplastic cellular immunization and humoral immunization, and curative effect is remarkable especially.
Describe embodiments of the invention below in detail.
Example 1.
Get the thick paraffin embedding cancerous tissue section of 50 μ m, immersed in the dimethylbenzene 12 hours, change in the dehydrated alcohol 12 hours then over to, immerse 95% ethanol more successively, 75% ethanol, in the PBS liquid each 30 minutes (in 75% ethanol, taking out the back) by strict sterile working, placing temperature then is 37 ℃ 0.14% collagenase 30 minutes, reuse 100 order nickel screens filter, make single cell suspension, then with PBS liquid washing 3 times, the trypsin of adding 1% was put 3 minutes or was put into microwave oven and handled 10 minutes, and reuse PBS liquid washing 3 times adds bacillus calmette-guerin vaccine or PPD, add dialdehyde or 0.03% formaldehyde, the packing of peace bottle at last of 0.025% penta again.
Example 2.
Get the thick paraffin embedding cancerous tissue section of 50 μ m, immersed in the dimethylbenzene 12 hours, change in the dehydrated alcohol 12 hours then over to, immerse 95% ethanol more successively, 75% ethanol, in the PBS liquid each 30 minutes (in 75% ethanol, taking out the back) by strict sterile working, placing temperature then is 37 ℃ 0.14% collagenase 30 minutes, reuse 100 order nickel screens filter, make single cell suspension, then with PBS liquid washing 3 times, the trypsin of adding 1% was put 3 minutes or was put into microwave oven and handled 10 minutes, reuse PBS liquid washing 3 times, hatched under 37 ℃ 20～30 minutes with 0.5～3% garlicin or Aloe extraction solution then, reuse PBS liquid washing 3 times adds bacillus calmette-guerin vaccine or PPD, add 0.025% glutaraldehyde or 0.03% formaldehyde again, at last the packing of peace bottle.
