Description
Technical field:
The present invention relates to the method that a kind of people of extraction urinates lutropin.
Background technology:
It is that molecular weight is 29Kda, contains three sugar chains by the hypophysis excretory, by the non-covalent heterodimer glycoprotein that is combined into of two different subunits of α, β that the people urinates lutropin.The people is kept in the existence of sugar chain, and to urinate the lutropin biological value essential, and the variation of its terminal sialic acid content has formed different electric charge isomer.The α subunit that the people urinates lutropin has identical amino-acid sequence with Urofollitropin, thyrotropin, chorionic gonadotrophin, and the difference of β subunit has caused different biological activitys separately.
Prove after deliberation, developed country has 15～20% Mr. and Mrs not give birth to approximately, cause and do not give birth to multiple reason, the common cause of atocia is to cause ovulatory dysfunction because gonad-stimulating hormone lacks, the common cause of male sterility be sperm degenerate or quantity very little.It is all very important to the reproductive function of masculinity and femininity that the people urinates lutropin, for the male sex, it is spermatogeny and ripe necessary that the people urinates lutropin, for the women, it is that follicle maturity, egg cell division, ovulation, corpus luteum generate and keep the essential gonadotropin of progesterone secretion luteal phase that the people urinates lutropin.
Therefore, the people urinates lutropin and has therapeutic value, can be used for the treatment of the people and urinate a series of diseases that the lutropin shortage causes.And at present the people to urinate lutropin be to play a role by fixed proportion with Urofollitropin in the postmenopause urine promoted gonadofrophin preparation, clinical application has been caused very big restriction.
Summary of the invention:
The objective of the invention is to provide a kind of people of extraction to urinate the method for lutropin, urinate from postmenopause urine promoted gonadofrophin or people and extract highly purified people the lutropin crude product and urinate lutropin, to be used for clinical treatment.
The present invention is achieved in that urinating the lutropin crude product with postmenopause urine promoted gonadofrophin that extracts from postmenopausal women's urine of suitably tiring or people is starting raw material, wherein postmenopause urine promoted gonadofrophin or the people biological value of urinating the lutropin crude product does not wait from every milligram 1 international unit to 300 international unit, adopt suitable ion exchange layer analysis method, comprise anionic exchange medium chromatography or cation exchange medium chromatography, both can use wherein a kind of chromatography method, can use simultaneously by two kinds of chromatography methods again, and the front and back order can be exchanged, starting raw material postmenopause urine promoted gonadofrophin or people are urinated the lutropin crude product carry out preliminary purification, the anion-exchange chromatography medium, active group is diethylamino ethyl (DEAE), diethyl quaternary amine (Q), diethyl hydroxypropyl quaternary amine (QAE) etc., carrier is to be (Sepharose), dextran (Sephadex) and Mierocrystalline cellulose (Cellulose) etc., to select Q-Sepharose for use is excellent, to cation-exchange chromatography, the active group of chromatography media is sulfonic group (S), sulfonic acid propyl group (SP), carboxymethyl (CM) etc., carrier is agarose (Sepharose), dextran (Sephadex) and Mierocrystalline cellulose (Cellulose) etc., select for use headed by the SP-Sepharose, chromatography condition, ionic strength is 0.01M～0.5MNaCl or KCl, adopt 0～1M NaCl or KCl linear gradient elution, fraction collection or stepwise elution, collection or merging contain the people and urinate the lutropin active part, anion-exchange chromatography pH is controlled at 4.0～10.0, pH is at 3.8～pH7.5 in cation-exchange chromatography control, collect liquid and can or use acetone with lyophilize, organic solvent deposit methods such as ethanol obtain to be suitable for being further purified the dry-matter of usefulness, also can be with method concentrating and desalinatings such as ultrafiltration, be directly used in subsequent technique, with the ethanol sedimentation method is excellent, the alcoholic acid final concentration is 70～90% during precipitation, with 80% is excellent, dry-matter or concentrated solution with acquisition in above-mentioned are raw material, carrying out hydrophobic chromatography is further purified, chromatography media is Phenyl Sepharose or OctylSepharose or Butyl Sepharose, it is excellent selecting Phenyl Sepharose for use, adsorption conditions is pH4-8, and solution contains 0.5-2M NaCl or (NH
