Abstract
A process for purifying insuline includes such steps as salting out, sodium salt crystallizing, zinc salt recrystallizing, and collecting dried insuline crystal powder. Its advantages are short period and high output rate.
Description
Technical field
The invention relates to the purification process of Regular Insulin, the crystallization method of the Regular Insulin of more specifically saying so is used to prepare high purity insulin.
Background technology
At present, known insulin production mostly adopts zinc crystallization technology, and its technical process is: the thing lysate of saltouing → remove acid albumin → filtrations → zinc precipitation → dissolving → and except that basonuclin → filtration → crystallization → collection drying.Its shortcoming is that product yield is low, operation steps is many, production cycle is long, the supplementary product onsumption height, in the technology simultaneously output need again recovery article about 15%, in particular for high purity insulin production, obviously its technology is unreasonable, Chinese patent publication number CN1077203A invention disclosed patent application " a kind of crystallizing process of insulin sodium salt ", its technology is: the thing lysate → filtration → crystallization of saltouing → drying collection → insulin sodium salt crystal powder.This technology is compared with zinc crystallization technology, and operation is few, and is with short production cycle, only improves 3-5% but the shortcoming that exists is the yield of tiring.
Summary of the invention
The objective of the invention is, a kind of purification process of Regular Insulin is provided, this method not only makes Regular Insulin purity height, stable yield, and overcome the CN1077203A patent application yield shortcoming on the low side of tiring.
Technical scheme of the present invention is: its purification process is: Regular Insulin saltout thing → sodium salt crystal → recrystallization → collection dry the insulin crystals powder; The method of sodium salt crystal is:
The Regular Insulin thing of saltouing becomes the lysate (W/V) of 20-30% with the 0.1N diluted hydrochloric acid dissolution; With the 10N sodium hydroxide solution this lysate is transferred about PH7, added 0.5-2/
10The sodium chloride solution of 30% concentration of amount stirs; Mend with the 5N sodium hydroxide solution again and transfer to PH7.5-8.5, stirring at room crystallization 8-10 hour.Leave standstill again, crystallization is avaled fully after, inhale and to remove supernatant liquor, with centrifugal or filtering method collection crystallization; Cold sodium chloride solution with concentration 2-10% is washed crystallization 1-2 time, gets the wet crystallization of insulin sodium salt.The method of recrystallization is:
The wet crystallization of insulin sodium salt is analysed dried by 26-30%, calculate cumulative volume by the 0.5-2% densitometer; Add solid citric acid 1-1.5 gram by every gram dry product, be dissolved in water into about 1/3 amount of cumulative volume again; Leave standstill 10-15 hour after-filtration and get clear filtrate the cold house; Adding concentration by 1-1.5 gram dry product in filtrate is 20% zinc acetate solution 1-2ml, cold acetone 16-20ml, be diluted to cumulative volume with cold water again after, transfer PH6.0-6.5 with 4N ammoniacal liquor, stir at a slow speed more than 5 hours, change the cold house over to and leave standstill crystallization is avaled fully.The collection drying means is:
Suction goes supernatant liquor to collect crystallization with centrifugal method, and with cold distilled water washing 1-2 time, acetone, ether dewater, do siccative vacuum-drying with Vanadium Pentoxide in FLAKES then, promptly get the insulin crystals powder again.
Term " Regular Insulin saltout thing " is that present technique field professional is known.
Described cold house is meant centigradetemperature 5-10 ℃.
Advantage of the present invention is: overcome the shortcoming of simple zinc crystallization or simple sodium salt crystal, insulin crystals yield and purity are improved, the yield of tiring improves 10-15%.
