瓊脂素
英文
agaroidin-
Various overlay mediums, such as agar, starch gel, methyl cellulose and tragacanth are used.
常用的覆蓋培養基有：瓊脂、澱粉凝膠甲基纖維素和黃蓍膠等。The seedlings were then growing on the medium for 20 days. the primary results show that the tolerable concentration of kanamycin to the tested seedlings is up to 15ug / ml and the suggested concentration for selection of resistant plant is 25ug / ml
為篩選卡那黴素抗性的轉基因植株，還進行了甘藍型油菜卡那黴素敏感性實驗。將正常甘藍型油菜種子表面消毒后，接種于不同濃度卡那黴素ms瓊脂培養基上，光照培養、篩選。A method for preparation of antithrombin ( at - ) concentrated from human plasma ' s fraction has been described. after preliminary treatment of plasma with the cold ethanol, the isolation of at - iii from the precipitate was performed by affinity chromatography on heparin - sepharose cl - 6b ; desalted by dialysis and concentrated
從人體血漿中提取較高純度的抗凝血酶（ at - ）的，通過低溫乙醇處理血漿，得到的沉澱經肝素-瓊脂糖兩次親和層析，並透析、濃縮獲得at -的初品。Bap performed more important function than kt in differentiation of tall fescue embryogenic calli, but better results could be achieved with combination of 2mg / l bap and 0. 5mg / l kt. at this cytokinin level, 0. 5mg / l naa was recommended to obtain the highest callus regeneration frequency. plant regeneration could be evidently boosted when embryogenic calli were pre - differentiated on high - osmoticum medium with 60g / l sucrose, and / or when the pre - differentiated compact calli were differentiated on differentiation medium solidified with l0g / l agar
高羊茅胚性愈傷組織分化時， bap的作用要比kt大，但2mg lbap與0 . 5mg lkt配合可獲得更佳的效果；在該細胞分裂素水平下，生長素naa用0 . 5mg l ，愈傷組織再生率最高；胚性愈傷組織先在含60g l蔗糖的分化培養基上高滲預分化，以及經高滲預分化后的緻密愈傷組織在瓊脂濃度為10g l的分化培養基上分化，能明顯促進愈傷組織的植株再生；在分化培養基中添加脯氨酸導致愈傷組織再生率下降，但同時有減少白化苗再生的趨勢。In order to investigate the role of mannose receptor ( mr ) of human sperm, the zona free hamster eggs were pre - incubated with purified mr ( pmr ) isolated from motile human sperm by mannose - agarose gel affinity chromatography. the ultrastuctural alteration and cortical granule exocytosis of the eggs were then observed by transmissian electron microscope and tritc - lca immunofluorescence microscope, respectively. the mice were immunized with pmr and the antiserum was raised. after capacitation and induction of the acrosome reaction, the human spermatozoa and oocytes were incubated with the antiserum. then the sperm penetration assay was undertaken
為了進一步探討人精於mr在精卵融合中的作用，本文採用改良后的甘露糖-瓊脂糖凝膠親和層析法分離純化人精子mr ，並將提純的人精子甘露糖受體（ purifiedmannosereceptor ， pmr ）作用於去透明帶的金黃地鼠卵母細胞，運用透射電子顯微鏡技術和羅丹明偶聯的兵豆凝集素（ tritc - lca ）免疫熒光標記技術觀察pmr對卵子的影響。Test method for agar diffusion cell culture screening for cytotoxicity
瓊脂擴散細胞培養屏蔽細胞毒素的試驗方法Main works and their important results are showed as following. firstly, the cdna encoding bullfrog gh is amplified by use of the total rna, extracted from adult bullfrog ' s pituitary, as the template, pi ( 5 ' - cggatcc atg gct tca ggg tta ggc ) and p2 ( 5 ' - cgaattc tta aaa ggt gca gtt gct ) as the primer pair and one particular cdna product, 660bp, was obtained after the rt - pcr - the product was purified by using dna agarose gel extraction method. after the purified cdna and pmd18 - t vector were ligated at 16 over night, the ligation products were transformed into e. coli strain dh5a and then the transformants were screened by clone pcr method
首先，以成體牛蛙的腦垂體總rna為模板，進行rt ? pcr擴增得到約660bp的特異性pcr產物帶，切下瓊脂糖凝膠中的特異產物帶進行cdna膠回收，將cdna與pmd18 ? t載體進行t ? a克隆連接並轉化到dh5 e . coli后，進行菌落pcr 、質粒酶切鑒定，篩選出陽性菌株，測序結果經blast分析，與已報道的牛蛙生長激素基因高度同源，證實此陽性克隆為牛蛙生長激素基因轉化子，命名為pbfgh 。The phenomenon of vitrification phenomenon is a big obstruction in the propagantion of carnation by tissue culture, the effective way to decrease the vitrification phenomenon is to increase the concentration of sucrose and agar in the medium, to use strong luminosity of 10000 - 20000 lx, and to decrease the concentration of hormone
摘要香石竹試管苗玻璃化現象給試管苗的應用帶來困難，採用強光照10000 - 20000lx ，在培養基中提高蔗糖和瓊脂濃度，降低激素用量，對克服香石竹試管苗玻璃化有明顯效果。分享友人
