  • activity : n. 1. 活動;活躍;動作;活動力;能動性。2. 活性;放射性。3. 機能,功能。4. 〈美國〉機構。5. 〈pl. 〉 活動范圍。
  1. The cell extract aliquots were added by ammonium sulfate with 30 %, 40 %, 50 %, 60 %, 70 %, 80 % and 90 % saturation, separately. the activities of sod for the re - suspensions were detected after dialysis and centrifugation. it was found sod activity could be detected after the precipitation by ammonium sulfates with 30 % saturation or above, and the highest sod activity could be obtained by precipitation of ammonium sulfate with 80 % saturation

    Maltophilia276菌株細胞提取物中分別加入飽和度為30 、 40 、 50 、 60 、 70 , 、 80和90的硫酸銨,經過透析、離心、重新懸浮后檢測sod的活性發現:當硫酸銨的飽和度為30時,其活性可檢測出sod活性,當硫酸銨的飽和度為80時,檢測出的sod活性最大。
  2. For a - early f type ms stars, stellar chromospheric activity decrease with stellar rotation period, but increase with rossby number ; for m type ms stars, stellar chromospheric activity increase with stellar rotation period and rossby number, and stellar chromospheric activity reach saturation at large color index ; for the ms stars between mid - f to m type, stellar chromospheric activity decrease with stellar rotation period and rossby number

    A ?早f型主序恆星的自轉周期和恆星對流區的隨色指數的分佈明顯地影響著這些恆星的色球活動行為。而m型主序星的色球活動水平基本上隨自轉參量的增大呈上升趨勢,並且m型主序星的色球活動水平在色指數較大時趨于飽和。
  3. 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

    通過sds一聚丙烯酸胺凝膠電泳可知該sod酶的分子量約為20kda .在非變性聚丙烯酞胺凝膠( pagb )電泳后,在凝膠son顯色反應液中加入0 . 2耐01 / lkcn或0 . 5inmol / lh202 ,凝膠sod顯色反應后在原來的sod酶部位仍然含有sod活性帶,這表明利用kcn和h20 :處理並不能抑制500的活性,該sod屬于mn一sod 。
