Abstract
The invention discloses a large-scale manufacturing method of high-precision T (containing fixed medium and carbon source) culture matrices and belongs to the technical field of plant biology. The large-scale manufacturing method comprises the following steps: firstly calculating the demand quantity of 11 elements contained in the matrices after amplifying by 1000 times and the demand quantity of CuSO4.5H2O in the very small demand quantity after amplifying by 10000 times; accurately weighing medicines; sequentially mixing and sealing the 11 elements according to the demand quantity; dissolving CuSO4.5H2O in 1L of distilled water for later use; and respectively unsealing according to needs. The matrices after amplifying, prepared by the method, have the characteristics of high precision, convenience in operation, high speed, simple application and small errors between different batches and in the same batch, and can be applied to plant tissue culture and other biotechnical applications.
Description
Technical field
The invention discloses the scale preparation method of a kind of high accuracy T (containing mounting medium and carbon source) culture matrix, belong to plant biotechnology field.Be more particularly one include accurate calculating, accurate weighing, first few after how mix, seal, mother liquor preparation separately, six steps such as use of breaking seal, to acquisition different batches and batch between the minimum culture matrix of error, minimizing experimental error method.
Background technology
Plant tissue culture technique or cultivation technique without soil need preparation medium mother liquor usually, and namely preparation expands certain multiple, liquid containing all kinds reagent.But, because mother liquor contains dissimilar reagent, be usually divided into the large class of macroelement, trace element, molysite and organic element four, and the multiple that four large classes expand is different, causes medicine service property (quality) inconsistent, easily occurs the error of calculation first; Second the producer of medicine, quality are inconsistent, even if to calculate, weigh consistent, also can affect result of the test; Three due to mother liquor be liquid condition, at the end of spring and the beginning of summer season, because the temperature rises and humidity increases, extremely easily cause mother liquor bacterial infection, mould, cause the phenomenon presenting different colours in mother liquor or occur precipitation, waste raw material; Comparatively big error can be there is to the difference of the cognition of container scale (especially trace element), instrument precision in four fundamental rules because of weighing person.
In view of the above-mentioned shortcoming of mother liquor; with the mother liquor medium of routine; usually there will be the failed phenomenon that maybe cannot repeat of the result of the test caused because of factors such as weighing person, medicine, seasons; have impact on the process using Plant Tissue Breeding or cultivation technique without soil to carry out test greatly, hit the confidence of experimenter.
Summary of the invention
A kind of scale preparation method of high accuracy T (containing mounting medium and carbon source) culture matrix; it is characterized in that, include in described method accurate calculating, accurate weighing, first few after how mix, seal, prepared by independent mother liquor, six steps such as use of breaking seal.
Method according to claim 1, is characterized in that, six described step concrete operations are as follows:
1. accurately calculate: 11 kinds of elements contained by T minimal medium are expanded 1000 times, i.e. Sodium Molybdate Dihydrate 0.25g, boric acid 10g, four water manganese sulphate 25g, iron edetate 36.5g, potassium dihydrogen phosphate 170g, epsom salt 370g, calcium chloride dihydrate 440g, ammonium nitrate 1650g, potassium nitrate 1900g, agar powder 5000g, sucrose 10000g; 1 kind of cupric sulfate pentahydrate expands 10000 times, i.e. 0.25g;
2. accurate weighing: according to the result precise of 1. middle calculating, especially with the cupric sulfate pentahydrate of ten thousand/balance precise 0.25g;
3. how to mix after first few: mix according to few priority of carrying out of amount more, namely according to Sodium Molybdate Dihydrate, boric acid, four water manganese sulphates, iron edetate, potassium dihydrogen phosphate, epsom salt, calcium chloride dihydrate, ammonium nitrate, potassium nitrate, agar powder, the order of sucrose mixes, and amounts to 19601.75g;
4. seal: the requirement of mixed solid matrix according to 250g every bottle is sub-packed in plastic containers, and seals;
5. mother liquor preparation separately: cupric sulfate pentahydrate weighs 0.25g, is dissolved in 1L distilled water, is mixed with 10000 times of mother liquors;
6. to break seal use: as required, add the above-mentioned solid matrix 19.6g of precise in every 1L distilled water, heating adds the independent mother liquor of 100 μ L cupric sulfate pentahydrates after it dissolves completely, and then adds reagent needed for other.
Beneficial effect of the present invention: the scale preparation method of this high precision culture matrix has following characteristics, i.e. without the error of calculation between the matrix of different batches; Because 11 kinds of reagent all expand 1000 times, a kind of reagent expands 10000 times, and the weighing error between the matrix of different batches is minimum, and precision is high; In theory, due to the usage amount (calculating with each 1L) that solid matrix is 1000 times at every turn, namely the above-mentioned formula of 1000L can be prepared, liquid mother liquor only needs 100 μ L at every turn, and batch inside there will not be the human error caused because using the reagent of different manufacturers, different times; Solid matrix after expansion is that every 250g is sealed in plastic containers, can avoid because the impact of the extraneous factor such as weather, temperature, moisture causes occurring the common precipitation of liquid mother liquor, the phenomenon such as mouldy, and fluid matrix is only the mixing of two kinds of elements.After expanding 10000 times, precision is high; Above-mentioned plurality of advantages is all the follow-up test carried out for matrix with this medium, obtains result of the test accurately and lays the foundation.。
