The cleavage culture solution comprises a composition for processing and cultivating oosperms, a bactericide, a selectively added indicator and selectively added human serum albumin. Various indexes of the cleavage culture solution disclosed by the invention achieve the standard of an in vitro culture solution, the cleavage culture solution is safe to use, strong guarantee is provided for an assisted reproduction technology, and whether the culture solution goes bad or not is easily judged by adding the indicator, therefore, the cleavage culture solution is safe and convenient to use.
Description
Technical field
The present invention relates to human assistance reproductive technology, relate in particular to a kind of spilting of an egg nutrient solution and preparation method thereof.
Background technology
Spilting of an egg nutrient solution is cultivated and is widely used in tube-test baby techniques the division of zygote.The object of spilting of an egg nutrient solution is: one is to provide the nutrition of development of fertilized ova; The 2nd, for the growth of zygote provides necessary environment.The purposes of spilting of an egg nutrient solution: laboratory or clinical zygote first day to the cultivation of three days to people under carbon dioxide environment.
At present, the spilting of an egg nutrient solution dependence on import finished product in China's auxiliary procreation technology, the quality of the validity of the high and solution of cost can not well show, if still continue to use after nutrient solution is rotten, will cause irreversible result to experiment or clinical manipulation.
Summary of the invention
The standard that the object of the present invention is to provide a kind of indices to reach vitro culture liquid used safely, be easy to the spilting of an egg nutrient solution that judges that whether nutrient solution is rotten, for auxiliary procreation technology provides strong guarantee.
Spilting of an egg nutrient solution of the present invention, comprises zygote is processed to composition, the sterilant of cultivating.
Described sterilant is gentamicin, concentration 9.5-10.5mg/L.
In described composition, comprise sodium-chlor 90.25-99.75mmol/L, Repone K 2.375-2.625 mmol/L, magnesium sulfate 0.38-0.42mmol/L, glucose 0.19-0.21mmol/L, calcium chloride 0.19-0.21 mmol/L, ethylenediamine tetraacetic acid (EDTA) 0.012-0.014mmol/L, Sodium.alpha.-hydroxypropionate 1.4176-1.5669g/L, Sodium.alpha.-ketopropionate 0.19-0.21mmol/L, sodium bicarbonate 23.75-26.25mmol/L, Dipeptiven 0.95-1.05mmol/L, taurine 0.38-0.42mmol/L, 4-hydroxyethyl piperazine ethanesulfonic acid HEPES 2.375-2.625mmol/L, non-essential amino acid 0.95-1.05%(v/v), gentamicin 9.5-10.5mg/L.
Described non-essential amino acid is one or several in ALANINE, altheine, L-Aspartic acid, Pidolidone, glycine, L-PROLINE, Serine.
The solvent of spilting of an egg nutrient solution adopts ultrapure water.
In spilting of an egg nutrient solution, contain human serum albumin 9.5-10.5%, v/v, can add or the front interpolation of packing in use.
In described spilting of an egg nutrient solution, can also selectivity add indicator phenol red, concentration 4.75-5.25mg/L.
The pH=7.20-7.40 of spilting of an egg nutrient solution of the present invention, osmotic pressure 260-290mOsm/Kg.
The preparation method of spilting of an egg nutrient solution of the present invention, comprises step below:
(1) preparation of basal liquid
A, elder generation proportionally weigh each component, and separated;
B, first load weighted component (except sterilant, selectivity add indicator, sodium bicarbonate, human serum albumin) is dissolved in ultrapure water, in dissolution process, follows liquid after first solid, NaHCO
3the principle finally adding;
C, to adding in step b gained solution load weighted sterilant, selectivity to add indicator and NaHCO
3;
D, the basal liquid that configures is placed to 37 ℃, 5.5% CO
2balance 6-12 hour in incubator, this step is used for regulating PH within the scope of 7.20-7.40.
(2) stoste of spilting of an egg nutrient solution preparation
A, the basal liquid of spilting of an egg nutrient solution is utilized under Bechtop to the membrane filtration degerming of 0.2 μ m, obtain filtrate A;
B, in filtrate A, add human serum albumin, shake or be uniformly mixed, obtain the stoste of spilting of an egg nutrient solution; Or omit this step, the stoste using filtrate A as spilting of an egg nutrient solution, adds human serum albumin as required voluntarily when doctor uses.
(3) processing of spilting of an egg nutrient solution stoste
Under gnotobasis, the stoste of spilting of an egg nutrient solution is carried out to coating-dividing sealing, obtain commercially available spilting of an egg nutrient solution, placed in refrigerator or freezer and preserve.
(4) spilting of an egg nutrient solution detects
Get the spilting of an egg nutrient solution minute installing and detect, test item is that pH value, osmotic pressure, cytotoxicity, intracutaneous stimulation, sensitization, aseptic, pyrogen, bacterial endotoxin, external mouse embryo test to judge that whether spilting of an egg nutrient solution is qualified.
The invention has the beneficial effects as follows, 1, the raw material of spilting of an egg nutrient solution of the present invention is all materials of verified its security, in preparation process, its solvent adopts ultrapure water, and (TOC) is ultralow for the total organic carbon of ultrapure water, has avoided too much affecting because of impurity the result of mensuration.2, use the usually growth of anti-bacteria of antibiosis, if gentamicin is the microbiotic of a kind of wide spectrum, Heat stability is good, in spilting of an egg nutrient solution, add the effectively growth of anti-bacteria of gentamicin.3, the domestic nutrient solution for tube-test baby techniques that also there is no moulding, this formula and preparation method provide strong assurance for domestic tube-test baby techniques, the not clear factor of having avoided external product to bring because of long-distance transport, blending process is simple to operate rationally simultaneously, detect tightly, can provide fresh nutrient solution for reproductive center or scientific research institutions.4, in spilting of an egg nutrient solution, selectivity adds indicator phenol red, phenol red when pH changes colour-change obvious, pH is at 7.20-7.40, in scope, phenol red solution is that pink is to orange red, it when pH value is less than 6.8, is yellow, it when pH value is greater than 8.4, is redness, variable color is obvious, the pH7.20-7.40 of spilting of an egg nutrient solution solution within the scope of this is that pink is to orange red, when spilting of an egg nutrient solution color is not inconsistent therewith, illustrate that this spilting of an egg nutrient solution is rotten, can not be for experiment or clinical, thus avoided using rotten spilting of an egg nutrient solution and the risk that produces.If do not contained phenol red indicator, solution is transparent, limpid, can guarantee before the deadline aseptic and normally use, and needs special concern product stock, transport condition and validity period.
Embodiment
The present invention is described further by the following examples.
One, spilting of an egg nutrient solution formula and preparation method

4 vitro culture
Employing micro drop method is cultivated, and the mouse embryo of collecting is divided into a positive controls, a negative control group and a trial-product group at random, is placed in Balanced nutrient solution, in 37 ℃, and 5% CO
2, in the incubator of saturated humidity, cultivate.Every group of mouse embryo number is no less than 50.
5 test-results
The external cultivation respectively after 96 hours of 1-cell stage recorded blastaea quantity.
Observation index: blastaea morphologic observation.
Acceptable value:
1) the Blastocyst formation rate of positive controls by statistics Epidemiological Analysis significantly lower than negative control group;
2) Blastocyst formation rate >=80 % of negative control group.
