查询词典 limpet

Methods PIWIL polypeptide was synthesized and conjugated to Keyhole limpet hemocyanin as an immunogen. Then PIWIL-KLH conjugations were injected into rabbits subcutaneously to produce polyclonal antibodies.

合成特异性PIWIL多肽，以马来酰胺活化匙孔血蓝蛋白作为载体构建多肽免疫原，通过致敏大白兔，制备兔抗人PIWIL多克隆抗体，用亲和层析法纯化抗体。

Methods ①Human peptides of CYP450 enzymes and their proteinic sequence were analyzed by means of bioinformatics, and certain sequences were chosen and synthesized according to four indexes (Hydrophilicity Plot, Flexible Regions, Antigenic Index and Surface Probability Plot) after homology analysis by software Blast. The synthesized peptides were conjugated to keyhole limpet hemocyanin to increase antigenicity.

①利用生物信息学方法分析CYP1A2、CYP3A4及CYP4A11蛋白的序列，利用DNAstar软件中蛋白质的亲水性结构、柔韧区、抗原指数及表面概率结构指标选择多肽序列，应用Blast软件对所选序列进行同源性分析并合成多肽，与载体蛋白钥孔戚血蓝素偶联，免疫大耳白兔制备抗CYP1A2、3A4及4A11抗体。

To prepare the phosphorylated PRAS40 (Ser183) antibody, We chosen 10-amino acid including Ser183 as antigen peptide through antigenicity and hydrophobicity analysis, hinged on keyhole limpet hemocyanin, and used the KLH-peptide to immunize rabbits. After antibody serum titer detection by enzyme linked immunosorbent assay, the antibody was purified with rProtein A sepharose fast flow and dephosphorylated antigen membrane. The antibody titrate reached 1:10 000 after purification and its special property was enhanced with absorption treatment of dephosphorylated antigen membrane. In addition, we used rabbit anti-PRAS40 antibody and the phosphorylated PRAS40 (Ser183) antibody to detect PRAS40 expression in several cell lines, including the normal cells HL7702, HEK293, tumor cells HepG2, A549 and S180. There were no quite difference among these cells; otherwise, we observed the decreased phosphorylation level of Ser183 after amino acid withdrawal treatment.

为了制备PRAS40(Ser183)磷酸化多克隆抗体，本实验通过蛋白疏水性抗原性分析设计多肽抗原，用其免疫家兔获得抗血清， ELISA检测其效价为1：10 000； Western blotting法检测发现，通过rProtein A Sepharose亲和层析纯化并经非磷酸化的抗原条吸附处理后的抗体可以明显提高磷酸化抗体的特异性；用PRAS40抗体及PRAS40(Ser183)磷酸化抗体对正常细胞HL7702、HEK293及肿瘤细胞HepG2、A549、S180的检测显示：磷酸化的Ser183在不同细胞中表达差异不显著，而在经细胞饥饿处理的HEK293细胞中却明显观察到了S183磷酸化水平随氨基酸含量降低而减弱的现象。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
