Description
Technical field
The present invention relates to field of biotechnology, and in particular to a kind of side using immobilization horse antibody extraction purification lipase
Method.
Background technique
Lipase, that is, Lipase, it be catalyzed natural substrate grease hydrolysis, generate fatty acid, glycerol and
Monoglyceride or diester.Lipase basic composition unit is only amino acid, usually only a polypeptide chain.Its catalytic activity is only
Only it is decided by its protein structure.Lipase is a kind of enzyme with a variety of catalytic capabilities, can be catalyzed triglyceride and
Hydrolysis, alcoholysis, esterification, the reaction of transesterification and esters reverse reaction of some other water-insoluble esters, in addition to this go back table
Reveal the activity of some other enzyme, such as phosphatidase, lysophospholipase, cholesterol esterase, acylpetide hydrolase activity.Lipase is not
With active the characteristics of playing dependent on reaction system, such as promote ester hydrolysis in oil-water interfaces, and can be with enzymatic in organic phase
Synthesis and transesterification.
Lipase widely exists in animals and plants and microorganism.What fatty enzyme was more is the kind of oil crops in plant
Son, such as castor bean, rapeseed, when oilseed germination, lipase can cooperate with to play a role with other enzymes is catalytically decomposed oil
Lipid material generates carbohydrate, provides nutriment and energy necessary to seed roots;Animal body include lipase it is more be
The pancreas and adipose tissue of higher mammal contain a small amount of lipase, for supplementing pancreatic lipase to fat digestion in intestinal juice
Deficiency, in the gastric juice of carnivore contain a small amount of tributyrinase.In animal body, each quasi-lipase, which controls, disappears
Change, absorb, fat is rebuild and the processes such as lipoprotein metabolism;Lipase content more horn of plenty in bacterium, fungi and yeast.Due to
Microbe species are more, breeding is fast, Yi Fasheng hereditary variation, have action pH more wider array of than animals and plants, operative temperature range and
Substratspezifitaet, and microbe-derived lipase is typically all the ectoenzyme of secretory, main fermentative microorganism has black song
Mould, Candida etc. is suitable for industrialized production and obtains high-purity sample, therefore microbial lipase is technical tallow
The important sources of fat enzyme.However, the microbial fermentation and extraction purification technology of existing lipase are still immature, product exists
Purity is low, if foreign protein is more, to obtain the product of purity is high, the problems such as but bringing complex process at high cost.
Summary of the invention
For the defects in the prior art, the present invention provides a kind of side using immobilization horse antibody extraction purification lipase
Method can effectively remove impurity, gained lipase purity is high, matter to utilize antigen-antibody specific bond extraction purification lipase
It measures, high income, it can also be purified when lipase concentration is lower, and production cost is low.
To achieve the above object, the present invention provides a kind of method using immobilization horse antibody extraction purification lipase,
Comprising steps of S1: using the pseudomonad of yielding lipase to ferment for fermenting microbe, obtain fermentation liquid;S2: by fermentation liquid from
The heart collects supernatant, obtains lipase crude enzyme liquid;S3: by immobilization horse antibody column on lipase crude enzyme liquid, cleaning solution is used later
Column is washed, then the disodium hydrogen phosphate used-citrate buffer solution elution, collects eluent, obtain lipase after purification;S4:
Polyethylene glycol is added in lipase after purification, precipitates lipase;It is centrifuged later, collects precipitating;It will be lyophilized after precipitating dialysis
It is dry, obtain lipase.It should be noted that after collecting lipase precipitating, the phosphoric acid buffer for the 0.1M for being preferably 7.2 with pH value
Liquid is dialysed, then is lyophilized.
S1 specifically includes step: the single bacterium colony of the pseudomonad of yielding lipase being placed in shake flask culture, in 20-30
DEG C, cultivate 16-20h under the conditions of 200-300rpm, be then transferred in fermentation culture by 10% inoculum concentration, 20-29 DEG C,
60-70h is cultivated under the conditions of 200-300rpm, obtains the fermentation liquid.
It preferably, include: yeast extract 5g, peptone 5g, vegetable oil 10g, surplus in every liter of shake flask culture in S1
For water;PH value is 7.0.
Preferably, in S1, include: yeast extract 10g in every liter of fermentation culture, peptone 5g, NaCl 0.5g, plant
Object oil 10g, surplus are water;PH value is 7.0.
In S2, centrifugation is to be centrifuged 14-16min under the conditions of 4 DEG C, 10000-11000g using high speed freezing centrifuge.
In S3, the preparation method of immobilization horse antibody column carries out 10-16 comprising steps of horse is immunized every two weeks primary altogether
Immune, each 2mL in week, dosage are respectively the Freund's complete adjuvant that 3-21mg lipase adds equivalent, multiple spot subcutaneous inoculation,
ELISA detection antibody titer collects antiserum after being greater than 1:10000;Antiserum is centrifuged off cell component and other precipitatings
Object uses proteinA or proteinG affinity column to be purified into polyclonal antibody after collecting supernatant;By polyclonal antibody
It is connect with the Sepharose2B of activation or Sepharose4B, obtains immobilization horse antibody column.
Preferably, in S3, the weight of horse is 210-370 kilograms, and the age of horse is 2-12 years old, and the kind of horse is Mongolian horse.
In S3, disodium hydrogen phosphate-potassium phosphate buffer that cleaning solution is the 0.1M that pH value is 7.2;Eluent is
0.1M disodium hydrogen phosphate-citrate buffer solution pH value is 3.
It further include that pH value is used to clean column to neutrality for disodium hydrogen phosphate-potassium phosphate buffer of 8 1M in S3
Step.Preferably, the buffer can be used to adjust eluent to pH value as 7.0.Explanation need to be used, this can make affinity column
Recycling, and keep lipase active.
In S4, centrifugation is to be centrifuged 5-10min under the conditions of 4 DEG C, 3000-5000g.
Technical solution provided by the invention, with following the utility model has the advantages that (1) is provided by the invention anti-using immobilization horse
The method of body extraction purification lipase can effectively remove impurity using antigen-antibody specific bond extraction purification lipase, special
Anisotropic strong, gained lipase is with high purity, high-quality, high income, activity height, can also carry out to it when lipase concentration is lower
Purification, it is high-efficient;It is monitored by antibody titer, selects high titre to resist for making affinity column more, lipase is effectively ensured
Yield and purity;(2) method provided by the invention using immobilization horse antibody extraction purification lipase, simple production process,
Production cost is low;Be easy to get polyclonal antibody, immune affinity chromatographic column can Reusability, discharge of wastewater and ring can be effectively reduced
Border pollution, is a kind of efficient lipase extracting method.
