  1. The hwtx - i gene was chemically synthesized according to its known cdna sequence, the gene was inserted into vector ppic9k which contained aoxj promotor and the sequence of a secreting signal peptide - a - factor, the cloning ppic9k / hwtx - i was constructed and confirmed by two - step pcr and dna sequence analysis, then it was transformed into host strain gs115, a his + muts cell line was screened and multicopy transformants were screened by various g418 concentrations, the multicopy transformant was named gh1. gh1 was cultivated in flasks. after 6 days of induction by 0. 5 % methanol, the supernatant was checked by 16. 5 % tricine - sds page, which showed there was a band in the position of 3. 5 - 6. 1kd, then it was isolated and desalted by ultrofiltration followed by ion exchange of cm column, after reverse phase hplc of ci8 and vacuum drying, the purified rhwtx - 1 was obtained which was proved to be correct recombinant hwtx - i by tricine sds - page, maldi - tof mass spectrometry, amino acid composition analysis, the n - terminal amino acid sequence and its biological activity, the final field of the purified rhwtx - i was about 80mg / l, accounting for 23. 6 % of it total secretory proteins

    將帶有hwtx -基因的ppic9k經blgii線性化后，轉化酵母宿主菌gs115原生質體后經篩選陽性克隆並經表型鑒定為his ~ + mut ~ s酵母菌，進一步用遺傳毒素g418篩選多拷貝的轉化菌株，命名為gh1 ；將gh1甲醇酵母菌用0 . 5的甲醇誘導表達，發酵上清經90飽和度的（ nh _ 4 ） _ 2so _ 4沉澱， yw - 3 （ mwc03000 ）的超濾膜超濾，再經cm陽離子交換， c _ （ 18 ）反相hplc純化得到分子量為4kd左右的組分，其中4289 . 05的組分經質譜鑒定，氨基酸組成分析和序列測定為正確的表達產物，生物學活性表明其活性為天然毒素活性70 % ，表達量為80mg / l 。
  2. The ade + transformants were selected and fermented in flasks with 20ml bmmy medium, then, induced by 0. 5 % methanol. the expression protein was analyzed by sds - page after five days of induction. sds - page analysis revealed that the high - level expression recombinant strains of pmad16 / pmet a b / abp2304 and pmad16 / pmet a a / abp780 had specific bands at 75kd and 55kd separately, account for 30 % and 10 % of the total protein separately, which were purified using probond resin purification system, and obtained 15mg at levels above 0. 75g / l and 7mg expression protein at levels above 0. 35g / l separately once purification, the purity is both above 90 %

    篩選ade +表型轉化子， 20mlbmmy搖瓶培養，用0 . 5甲醇誘導表達5天後， sds - page檢測結果表明：選出的重組高效表達菌株pmad16 pmet b abp2304和pmad16 pmet a abp780都存在明顯的表達特異條帶，分子量分別為75kd和55kd ，分別占其總蛋白的30和10 ，經過probondresin鎳親和層析柱都得到了純化，其純度都在90以上，一次純化分別可得到大約15mg和7mg表達蛋白，推知表達量分別高達0 . 75g l和0 . 35g l以上。
  3. Crumbs of nails were isolated from onychomycosis suffers, koh was chosen to be solvent, nail fungi were examined by microscopy, cultured in sabourud, purified by method of concentration grads and method of exsecting cusp of mycelia. finally, sixteen purified strains were ready

    從甲病患者病甲中分離出甲碎屑，選用koh為浮載劑，直接鏡檢，採用沙堡氏培養基對它們進行分離培養，濃度梯度法和切取菌絲尖端生長法對菌種進行純化，得到純化后的菌株16株。
