  4. The isolation and purification of dnaase in the earthworm the earthworm dnaase was purified from the tissue extract of earthworm by denaturing the protein with low ph buffer, high temperature, ammonium sulfate precipitation, deae - cellulose ( de52 ) chromatography and ultra - filter membrane

    雙胸蚓組織中dna酶的分離純化雙胸蚓組織粗提取液經過選擇性酸變性、選擇性熱變性、硫酸按分段鹽析、 deae一纖維素（ de52 ）柱層析、超濾膜分級分離后得到一個電泳純的dna酶。
  5. But the whole level of serum titer in combined vaccine group was higher than others. igg was extracted by salting out with ammonium sulfate and purified by ion exchange chromatography with deae cellulose

    對分離到的血清用飽和硫酸銨鹽析法提取igg ，並用deae纖維素離子交換層析法對提取的igg進行純化。
  6. To isolate and purify dnaase in the earthworm first, the tissue extract of earthworm was prepared by dissolving the earthworm with sucrose and denaturing the protein with low ph buffer. then dnaase was purified by denaturing the protein with higher temperature. the following steps were ammonium sulfate precipitation, deae - cellulose ( de52 ) chromatography and filtration by ultra - filter membrane

    雙胸蚓組織中dna酶的分離純化採用蔗糖溶解雙胸蚓，並選擇性酸變性制備雙胸蚓組織粗提取液，再經選擇性熱變性、硫酸銨分段鹽析、 deae ?纖維素（ de52 ）柱層析及超濾膜分級分離對雙胸蚓組織中dna酶進行分離純化。
  7. The enzyme was purified from cell extract by ammonium sulfate fractionation ( 30 % - 80 % saturation ) and consecutive column chromatography using deae - cellulose and sephadex g - 100. the sod activity for purified enzyme could reach 4966 iu / mg proteins, and the molecular weight of the sod was about 20 kda which determined by sds - page electrophoresis. when the non - denaturing polyacrylamide gel stained with substrate for sod in the present of 0. 2mmol / l kcn or 0. 5 mmol / l h2o2, the active band was still showed at the same position, which indicated the sod could not be inhibited by the treatments with kcn or h2o2 and it was the mn sod
