  • gradient : adj. 1. 傾斜的。2. 【動物；動物學】步行的，能步行的。n. 1. 〈英國〉（道路的）傾斜度，坡度，坡路。2. 【物理學】梯度，陡度，（溫度、氣壓等的）變化率，梯度變化曲線。
  • centrifugation : n. 離心（分離）。
  1. Purification : density gradient centrifugation ( sucrose & cscl )

    分離:密度梯度離心法（蔗糖&氯化銫）
  2. Density gradient centrifugation

    密度梯度離心
  3. In the first trial, combination of enzymatic digestion was used to prepare suspensions of spermatogenic cells from adult mouse testis, and then a modified discontinuous percoll gradient centrifugation method ( 15 %, 22 %, 30 %, 40 %, 50 %, 60 % ) was introduced to isolate spermatids from the cellular suspensions. the content of spermatids in each isolated fraction by percoll method was determined by morphology ( wright - giemsa stain ) and flow cytometry analysis, and the viability of spermatogenic cells was assessed by using eosin y exclusion test

    在第一部分試驗中，首先利用連續3次組合酶消化成年小鼠睪丸制備睪丸細胞懸液，然後經6層非連續percoll梯度離心法（ 15 、 22 、 30 、 40 、 50和60 ）分離，通過形態學和流式細胞術鑒定南京醫科大學碩士學位論文各個percoll組分中精子細胞的含量，並以伊紅y排斥試驗測定細胞的存活率。
  4. Methods using different techniques of collagenase digestion and discontinued density gradient centrifugation, the adult swine and rat islets were prepared

    方法採用不同的膠原酶消化法及不連續密度梯度純化法。
  5. Methods : gradient centrifugation and differential adherence were employed to isolate type pneumocytes from the lungs in the rats, proliferative activities were compared in the cultued cells from the young, adult and aged rats

    方法：應用梯度離心和貼壁培養分離大鼠肺泡型細胞，比較幼年、中年和老年大鼠培養肺泡型細胞的增殖能力。
  6. The fetal liver stem cells were isolated by collagenase digestion, gravity sedimentation and density gradient centrifugation, identified by immunocytochemistry and evaluated by flow cytometry for their proliferation condition

    採用膠原酶消化、重力沉降及密度梯度離心方法分離人胎肝幹細胞，通過免疫細胞化學方法對其進行初步鑒定，以及應用流式細胞儀等對其生長狀況進行評估。
  7. In the second trial, this modified discontinuous percoll gradient centrifugation method was introduced to isolate spermatids from the semen of fifteen male infertile patients. then the effect was identified by wright - giemsa stain, flow cytometry analysis, immunocytochemistry and fluorescence in situ hybridization ( fish ). similary, the 22 % percoll fraction contained mostly haploid cells [ ( 91. 85 ? 5. 18 ) % ] ( p < 0. 005 ) and the mean density in this fraction was ( 1. 010 ? 0. 786 ) x 105 / ml

    C法，對15例各種類型不育患者的精液細胞進行分離，並利用瑞姬染色法、流式細胞術、免疫細胞化學和熒光原位雜交oisffi等方法，從細胞形態特徵、 dna倍體、細胞表面標i己與分化抗原，以及原位雜交信號的數目和位置結合細胞核特有的形態等方面加以鑒定。
  8. So a lagre populations of relatively purified spermatids can be isolated from mouse testis by enzymatic digestion combined with discontinuous percoll gradient centrifugation method

    因此採用組合酶消化結合非連續percoll梯度離。 g法，可有效地從小鼠睪丸中分離到較多較純的存活精子細胞。
