The nuclei and nucleoli were extracted and purified and the sclerotia were induced from fuligo septica phaneroplasmodium, and then they were observed under tem 從煤絨菌顯型原質(zhì)團中提純細胞核、核仁,誘導(dǎo)原質(zhì)團形成菌核,并在透射電鏡下觀察。
After the produre of extracting and purifying immunogen, the production of monoclonal antibodies was carried out . three balb / c mice, 6-week old, were used for immunization 首先選擇六周齡的balb/c小鼠三只,按照免疫方案進行尾靜脈和皮下的注射。
The first part of our experiment is to extract and purify the total rna from the human liver tissue in the condition without rnase and to identify its integrity and purity 本研究第一部分包括肝組織中總rna的分離提??;rt-pcr擴增出血管抑素基因。首先,采集術(shù)后新鮮肝組織,并于無rnase的條件下分離純化總rna。
The recombinant was screened by pcr, cleaved by bamhi, bglll to determine the director, and then was named pci-cea . after growing in large scale, plasmids were extracted and purified and quantified . 2 pciil2的構(gòu)建:用oligo軟件設(shè)計弓物,在上、下游引物的5’端加上xhol和sail酶切位點,以便于與載體連接。
However, depending on the differences among e . coli strains, and the procedures used to extract and purify endotoxin that serves as standard for these measurements, some differences might occur in the specific activity 然而,依靠大腸桿菌張力的不同,用這些測量法的標準,過程中曾經(jīng)析取和凈化內(nèi)毒素,一些不同的力量存在比活性。
In this section i extract and purify out one concept : the function of this kind of newspaper is not merely give the magnanimity message to readers but to escort information receivers to contact with the information that they need 在應(yīng)對策略中,提煉出一個觀點:廠‘一播電子見j一仗節(jié)日表是信腳、的信窟、,其功能是作信啟、的向?qū)?,而并不是僅僅展示海量信息。
1 . isolation, purification and characterization of lipovitellin from the ovary of female eriocheir sinensis broodstock lipovitellin was extracted and purified using gel chromatography and electrophoresis procedures from ovaries of chinese mitten-handed crab . one kind of lipovitellin was obtained 一、中華絨鰲蟹卵黃磷蛋白的分離、純化與鑒定目前在判定蝦蟹卵巢成熟和卵質(zhì)時,大多采用性腺指數(shù)、蛋白質(zhì)和脂類的組成與含量等生化指標,尚不夠全面。
A eukaryotic expression vector pcdna3.1-cptl was constructed by insert cp77 gene into the vector pcdna3.1 which is used in nucleic acid immunization . the vector was immuned the balb / c mice by the method intramuscular injection after extracted and purified in great deal . immu-nological reaction was induced by the expression of cptl after the vector entered into the mice body 本研究通過限制酶將cpti基因片段從載體pbluel3上切下,插入真核表達載體pcdna3.1,構(gòu)建了用于核酸免疫的真核表達載體pcdna3.1-cpti;質(zhì)粒大量提取和純化后,通過肌肉注射的方法免疫balbc小鼠,基因表達產(chǎn)物刺激小鼠機體產(chǎn)生免疫反應(yīng),從而獲得了抗cpti蛋白的抗體。
